shiver ran down her spine.
     No one spoke for a while, neither Momo nor any of the men in grey. Then
a flat, expressionless voice broke the silence.
     'I see,' it said. 'So this is Momo, the girl who thought she could defy
us. Just look at her now, the miserable creature!'
     These  words  were  followed by  a  dry, rattling  sound  that  vaguely
resembled a chorus of mocking laughter.
     'Careful!' hissed another grey voice. 'You know  how dangerous  she can
be. It's no use trying to deceive her.'
     Momo pricked up her ears at this.
     'Very  well,'  said  the  first  voice  from  the  darkness beyond  the
headlights, 'let's try the truth for a change.'
     Another long silence fell. Momo sensed that the men in grey were afraid
to tell the truth - so afraid that it imposed a tremendous  strain on  them.
She heard what sounded like a gasp of exertion from a thousand throats.
     At long  last, one of the disembodied  voices  began to  speak. It came
from  a different direction, but it was just as flat  and expressionless  as
the others.
     'All right, let's be blunt. You're  all on your own, little girl.  Your
friends are  out of  reach,  so you've no  one to share  your time  with. We
planned it that way. You see how powerful we are. There's no point in trying
to  resist us. What  do they amount to,  all these lonely hours  of yours? A
curse and a burden, nothing more. You're completely cut off from the rest of
mankind.'
     200
     Momo listened and said nothing.
     'Sooner or later,' the voice droned on, 'you won't be able to endure it
any longer. Tomorrow, next week,  next year -it's  all  the same  to us.  We
shall simply bide our  time because we know that  in due  course you'll come
crawling to us and say: I'll do  anything, anything  at all,  as long as you
relieve me of my burden. But perhaps  you've already reached that stage? You
only have to say.' Momo shook her head.
     "So you won't let us help you?' the  voice pursued coldly. Momo felt an
icy breeze envelop her from all sides at once, but she gritted her teeth and
shook her head again.
     'She knows what time is,' whispered another voice.
     'That proves  she really was  with  a  Certain Person,' the first voice
replied, also in a whisper. Aloud, it asked, 'Do you know Professor ®£ ?'
     Momo nodded.
     'You actually paid him a visit?'
     She nodded again.
     'So you know about the hour-lilies?'
     She nodded a third time. Oh yes, how well she knew!
     There was another longish silence. When the voice began to speak again,
it came from another direction.
     'You love your friends, don't you?'
     Another nod.
     'And you'd like to set them free?'
     Yet another nod.
     'You could, if only you would.'
     Momo  was shivering with cold in  every limb. She drew the  jacket more
tightly around her.
     'It  wouldn't take much  to save them. You help  us and we'll help you.
That's only fair, isn't it?'
     The  voice was coming  from yet another direction. Momo stared intently
at its source.
     'The thing is, we'd like to make Professor Hora's
     201
     acquaintance  but we don't  Know where he lives. All we want is for you
to show us the way. That's right, Momo, listen carefully,  so you know we're
being  honest with you and mean what we say. In return, we'll give you  back
your friends and let you all lead the carefree, happy-go-lucky life you used
to enjoy so much. If that isn't a worthwhile offer, what is?'
     Momo opened her mouth for the  first time.  It  was quite an effort  to
speak at all, her lips felt so numb.
     'What do you want with Professor Hora?' she asked.
     'I told you, we want to make his acquaintance,' the voice said sharply,
and the air grew even colder. 'That's all you need to know.'
     Momo said nothing, just waited.
     'I don't understand you,' said  the  voice. 'Think of yourself and your
friends.  Why  worry about  Professor  Hora? He's  old enough to look  after
himself.  Besides,  if he's sensible and  cooperates nicely, we won't harm a
hair of his head. If not, we have ways of making him.'
     Momo's lips were blue with cold. 'Making him do what?' she asked.
     The  voice  sounded  suddenly  shrill  and  strained. 'We're  tired  of
collecting people's time by the  hour, minute and second. We want  all of it
right away, and Hora's got to hand it over!'
     Horrified, Momo stared into the darkness beyond the ring of headlights.
'What  about  the people it belongs to?' she asked.  'What  will  happen  to
them?'
     'People?' The  voice  rose to a  scream and  broke. 'People  have  been
obsolete for years. They've made  the world a  place where  there's  no room
left for their own kind. We shall rule the world!'
     By now the cold was so  intense that Momo could barely  move her  lips,
let alone speak.
     'Never fear, though, little Momo,' the voice went on, abruptly becoming
gentle and  almost coaxing, 'that naturally won't  apply  to  you  and  your
friends. You'll be the last and
     202
     only people  on earth to  play games  and tell stories. As long as  you
stop meddling in our business, we'll leave you in peace. Is it a deal?'
     '  The voice fell silent. A moment later, it  took up the thread from a
different quarter.  'You  know we've  told  you  the  truth.  We'll keep our
promise, you can rely on that. And now, take us to Professor Hora.'
     Momo tried to speak, almost fainting with cold.  Finally, after several
attempts, she said, 'Even if I could, I wouldn't.'
     'What  do you mean, if  you could?' the* voice  said  menac-ingly.  'Of
course you can. You paid him a visit, so you must know the way.'
     'I'd never find it again,' Momo whispered. 'I've tried. Only Cassiopeia
knows it.'
     'Who's Cassiopeia?'
     The professor's tortoise.'
     'Where is it now?'
     Momo, barely conscious, murmured, "She . . . she came back with me, but
... I lost her.'
     As  if from a  long  way off,  a chorus of agitated voices  came to her
ears.
     'Issue  a general alert!' she heard.  'We've got to find that tortoise.
Check every  tortoise  you come across. That animal's got to be found at all
costs!'
     The voices  died away.  Silence fell. Momo slowly regained her  senses.
She  was  standing  by  herself in the  middle of  the  square. Nothing  was
stirring but  a chill gust  of  wind that  seemed to  issue from some great,
empty void: a wind as grey as ashes.
        EIGHTEEN
     The Pursuit
     Momo didn't know how  much  time had  passed. The  church  clock chimed
occasionally, but she scarcely heard it.  Her frozen limbs took ages to thaw
out. She felt numb and incapable of making decisions.
     How could she go home to the amphitheatre and climb into bed, now  that
there was no hope left  for herself and her friends? How could she, when she
knew that  things would never  come  right  again?  She  was  worried  about
Cassiopeia, too.  What  if the men in grey found her? She began to  reproach
herself bitterly for having mentioned  the tortoise at all, but  she'd  been
too dazed to think straight.
     'Anyway,' she reflected,  trying to console  herself,  'Cassiopeia  may
have found her way  back to Professor ®£  long ago.  Yes, I hope she  isn't
still looking for me. It would be better for both of us.'
     At that moment something nudged her  bare  foot. Momo gave  a start and
looked down.
     There  was Cassiopeia,  as large as  life, and she could dimly see some
words on the animal's shell: 'HERE I AM AGAIN,' they said.
     Without a second  thought, Momo  grabbed  the tortoise  and  stuffed it
under her jacket. Then she  straightened  up and peered  in  all directions,
fearful that some men in grey might still be lurking in the shadows, but all
was quiet.
     Cassiopeia  kicked  and  struggled fiercely in  an  effort  to  escape.
Holding her tight, Momo peeped inside the jacket and whispered, 'Please keep
still!'
     204
     'WHY  ALL  THE FUSS?' demanded Cassiopeia. 'You mustn't be seen!'  Momo
hissed. The  next words to appear on the tortoise's shell were, 'AREN'T  YOU
GLAD?'
     'Of  course,' Momo said with a catch  in  her voice. 'Of course  I  am.
You've no  idea!'  And she kissed  Cassiopeia on the nose, several  times in
quick succession.
     Cassiopeia responded with two rather pink words. 'STEADY ON,'they read.
     Momo smiled. 'Have you been looking for me all this time?' 'OF COURSE.'
     'But how did you happen to find me here and now?' 'I KNEW I WOULD,' was
the laconic  reply.  Had Cassiopeia spent all those weeks  looking  for  her
although she knew she wouldn't find  her? If  so,  she  needn't  really have
bothered  to  look  at  all.  This  was yet another  of  Cassiopeia's little
mysteries. They  made Memo's head spin if she thought  about them  too hard,
and besides, this was scarcely the moment to puzzle over such problems.
     Momo gave the tortoise  a whispered account of what  had happened since
last they met. 'What should we do now?' she concluded.
     Cassiopeia had  been listening  attentively. 'GO TO HORA,'  she spelled
out.
     'Now?' Momo exclaimed, aghast. 'But they're looking for you everywhere.
This is the only place they don't happen to be. Wouldn't it be wiser to stay
here?'
     But all the tortoise's shell said was, 'WE'RE GOING ANYWAY.'
     'We'll run right into  them,' Momo protested.  'WON'T MEET A SOUL,' was
Cassiopeia's response. If Cassiopeia was sure, that settled it. Momo put her
down. Then, remembering  their  first long, arduous  trek, she suddenly felt
too exhausted to repeat it all over again.
     205
     'You go  on alone, Cassiopeia,' she said wearily. 'I'm too tired. Go on
alone, and give the professor my love.'
     Cassiopeia's shell lit up again. 'IT'S NOT FAR,' Momo was astonished to
read.  It  dawned  on  her,  as  she  looked  around,  that  this shabby and
desolate-looking neighbourhood  might  be  the one that  led to the district
with the white houses and the strange shadows. If so, she might after all be
able to make it as far as Never Lane and Nowhere House.
     'All  right,' she said, 'I'll come too, but wouldn't it be quicker if I
carried you?'
     'AFRAID NOT,' Cassiopeia replied.
     'Why should you insist on  crawling there by yourself?'  Momo said, but
all she got was the enigmatic reply: 'THE WAY'S INSIDE ME.'
     On that note the tortoise set off  with  Momo following slowly, step by
step.
     They  had only just  disappeared  down a side street  when the  shadows
around the square came to  life and the air  was filled with a brittle sound
like the snapping of dry twigs: the men in grey were chuckling triumphantly.
Some of their number, who had stayed behind to keep a surreptitious watch on
Momo, had witnessed her reunion with Cassiopeia. The wait  had been  a  long
one, but not even they had dreamed that it would yield such results.
     'There they go!' whispered one grey voice. 'Shall we nab them?'
     'Of course not,' hissed another. 'Let them carry on.'
     'Why?'  demanded  the  first  voice.  'Our  orders were to  capture the
tortoise at all costs.'
     'Yes, but why do we want it?'
     'So it can lead us to ®£ .'
     'Precisely, that's just what it's doing now. We won't even have to  use
force. It's showing us the way of its own free will - unintentionally.'
     206
     Another dry chuckle went up from the shadows around the square.
     'Pass the word at once. Call off the search  and instruct all Agents to
join us here. Tell them to exercise the utmost care, though. None of us must
be seen by our two  unsuspecting guides or get  in their way. They're to  be
given free passage wherever they go. And now, gentlemen, let's follow at our
leisure.'
     It  was hardly  surprising, under  these  circumstances, that Momo  and
Cassiopeia failed to encounter a single one of their pursuers. Whichever way
they went, the men in  grey melted away in good  time and joined the rear of
the evergrowing procession that  was silently, cautiously, following in  the
fugitives' wake.
     Momo  was wearier than she  had ever been in her life. There were times
when she thought she would simply sink to the ground and  fall asleep at any
moment,  but she  forced herself to put one foot before the other, and for a
while things went better. If only  Cassiopeia wouldn't crawl along at such a
snail's pace, she  thought, but it couldn't be  helped. She  trudged  along,
looking neither right nor left, only at her feet and the tortoise.
     After an eternity, or so it seemed  to  Momo, the surface of the street
grew suddenly paler. She wrenched her leaden eyelids open and looked around.
     Yes, they had finally reached the district where  the light was neither
that  of  dawn  nor  dusk,  and  where  all  the shadows  ran  in  different
directions. There were the forbidding white houses  with the cavernous black
windows, and  there  was the  peculiar,  egglike monument on its black stone
plinth.
     At  the thought that it wouldn't be long  before she saw Professor Hora
again. Memo's courage  revived. 'Please,' she said  to Cassiopeia, 'couldn't
we go a bit faster?'
     'MORE HASTE LESS SPEED,' came the reply, and
     207
     the tortoise crawled on even more slowly than before. Yet Momo noticed,
as she had the first time,  that they made better progress  that way. It was
as if the street beneath them glided past more quickly the slower they went.
     That,  of  course, was  the secret of the district with the  snow-white
houses: the slower you went the better progress you made,  and the more  you
hurried the slower your  rate of advance. The  men in grey hadn't known that
when they pursued Momo in their cars, which was how she'd escaped them.
     But that was the last time. Things were  quite different  now that they
had no intention of overtaking  the girl and the tortoise. Now, because they
were  trailing them at  exactly  the  same speed,  they had  discovered  the
secret. Gradually, the streets behind Momo and Cassiopeia became filled with
an army of  men in  grey.  And  as  the  pursuers  grew  accustomed  to  the
peculiarities of the district, they went even slower than their quarry, with
the result that they steadily overhauled them. It was like a race in reverse
- a go-slow race.
     On  and  on the strange procession went, further  and further into  the
dazzling white glow, weaving back and forth through the  dream streets until
it came to the corner of Never Lane.
     Cassiopeia  turned into  the lane  and crawled  towards Nowhere  House.
Momo,  remembering that she'd failed to make  any  headway until  she turned
around and walked backwards, did the same again.
     And that was when her heart stood still.
     The  time-thieves, like a  grey wall on the move, stretched away for as
far as the eye could see, rank upon rank of them filling the entire width of
the street.
     Momo cried  out in  terror, but  she couldn't  hear  her own voice. She
walked backwards down Never Lane, staring wide-eyed at the advancing host of
men in grey.
     But then another strange thing happened. As  soon as  the leaders tried
to enter the lane, they vanished before her very
     208
     eyes. Their outstretched hands were the first to disappear, then  their
legs and bodies,  and last of all their faces, which wore a look of surprise
and horror.
     But Momo wasn't the  only one to have witnessed this phenomenon. It had
also  been seen by the  men  in  grey who were following behind. They shrank
back, bracing themselves  to resist the pressure of those still advancing in
the rear, and something of a scuffle ensued. Momo saw her pursuers scowl and
shake their fists, but they dared not pursue her any further.
     At last she reached Nowhere House. The big  bronze door swung open. She
darted inside,  raced  down the corridor lined with statues, opened the tiny
door at the  other end, ducked through it, ran across the  great hall to the
little room enclosed by grandfather clocks, threw herself down on the dainty
little sofa, and, not wanting to see or hear  anything more, buried her head
under a cushion.
        NINETEEN
     Under Siege
     A genrie voice was speaKing.
     Momo emerged by degrees from  the depths of  a dreamless sleep, feeling
wonderfully rested and refreshed. 'Momo isn't to blame,' she heard the voice
say, 'but you, Cassiopeia - you should have known better.'
     Momo opened her eyes. Professor Hora was sitting at the little table in
front of the  sofa,  looking ruefully down at the tortoise. 'Didn't it occur
to you,' he went on, 'that the men in grey might follow you?'
     There wasn't room on Cassiopeia's shell for all she had to say, so  she
had to reply in three instalments: 'I CAN ONLY  SEE-HALF AN HOUR AHEAD - TOO
LATE BY THEN.'
     Professor Hora sighed and shook  his head. 'Oh, Cassiopeia, Cassiopeia,
even I find you puzzling sometimes.'
     Momo sat up.
     'Ah, our guest  is  awake,'  Professor Hora said kindly. 'I hope you're
feeling better?'
     'Much better, thank  you,'  said  Momo.  'Please excuse me  for falling
asleep on your sofa.'
     The  professor  smiled.  'It's  quite  all  right, you've  no  need  to
apologize. Cassiopeia has already brought me up to date on anything I failed
to see through my omnivision glasses.'
     'What are the men in grey doing?' Momo asked anxiously.
     Professor Hora produced a big blue handkerchief from his pocket. 'We're
under siege. They have us completely sur-
     210
     rounded -  that's to say, they're as close to Nowhere House as they can
get.'
     'But they  can't get in,  can they?' Momo said.  The professor blew his
nose.  'No, they can't. You saw for yourself,  they vanish into  thin air if
they so much as set foot in Never Lane.'
     Momo  looked mystified.  'Yes, but  I don't know  why.'  'It's temporal
suction that does  it,'  the professor told her.  'Everything has to be done
backwards in Never  Lane,  as you know, because time  runs in reverse around
this  house.  Normally, time flows into  you. The more time you  have inside
you,  the  older you get, but in Never Lane time flows  out of you. You grew
younger while  you were coming up the lane. Not much younger -  only as much
younger as  the time you took to get from one  end  to the other.' 'I didn't
notice anything,' Momo said, still mystified. 'That's because you're a human
being,' the professor said with a smile. 'There's a lot more to human beings
than the rime they carry around inside them, but it's different with the men
in grey. Stolen  time is all they consist of, and that disappears in a flash
when they're exposed to temporal  suction. It escapes like air from a  burst
balloon, the only difference being that a balloon's skin survives.  In their
case, there's nothing left at all.'
     Momo  knit her brow and  thought hard. 'Wouldn't  it  be possible,' she
asked at length, 'to make time run backwards all over the world?  Only for a
little while, I mean. It wouldn't matter if  people grew a tiny bit younger,
but the time-thieves would be reduced to nothing.'
     The  professor  smiled  again. 'A  splendid idea, I grant you, but  I'm
afraid it wouldn't work.  The two currents  are in  balance, you see. If you
cancelled one, the other would vanish too. Then there'd be no time left .  .
.'
     He broke  off and  pushed his omnivision glasses up so that they rested
on his forehead.
     211
     'On the other hand ...' he murmured. Momo watched him expectantly as he
paced  up and down  the room a few times,  lost in thought,  and  Cassiopeia
followed him with her wise old eyes. At length he sat down again.
     'You've  given me an idea,'  he  said, 'but  I  couldn't  put  it  into
practice unaided.' He looked down at the tortoise. 'Cassiopeia, my dear, I'd
like your  opinion on  something. What's the  best thing  to  do when you're
under siege?'
     'HAVE BREAKFAST,' came the reply.
     'Quite so,' said the professor. 'That's another splendid idea.'
     The table  was laid in a flash. Whether or not it had been laid all the
time and Momo simply hadn't noticed, everything was in place: the two little
cups, the pot of steaming chocolate, the honey, butter and crusty rolls.
     Momo, whose  mouth had often watered at the recollection  of her  first
delicious,  golden-hued  breakfast  at  Nowhere House,  tucked  in at  once.
Everything tasted even  better than before, if  possible,  and this time the
professor tucked in heartily too.
     'Professor,'  Momo  said after a while,  with her cheeks still bulging,
'they  want you to give them all  the time  that exists. You won't,  though,
will you?'
     'No, child,' he replied, 'that I'll never do. Time will come  to an end
some day, but not until people don't  need  it any longer.  The men in  grey
won't get any time from me - not even a split second.'
     'But they say they can make you hand it over,' Momo said.
     'Before  we  go into that,' the professor told her,  very gravely, 'I'd
like you to look at them for yourself.'
     All she saw to begin with  was  the kaleidoscope of colours  and shapes
that had made her  so dizzy the first time,  but  it wasn't  long before her
eyes got used to the omnivision  lenses. And then  the  besieging  army swam
into focusi
     212
     The  men  in grey were  drawn  up in  a  long,  long line, shoulder  to
shoulder,  not only  across the mouth  of  Never  Lane  but  all around  the
district with the snow-white houses. They formed an unbroken cordon, and the
mid-point of that cordon was Nowhere House.
     But  then Momo  noticed something else -  something strange. Her  first
thought was  that  the lenses of the omnivision glasses needed polishing, or
that she hadn't quite grown  used to them yet,  because  the outlkies of the
men  in grey looked misty. She soon  realized that this blurring had nothing
to do with the lenses or her eyes: the mist was real, and it was rising from
the streets all  around,  dense and impenetrable in some  places, only  just
forming in others.
     The men in grey were standing absolutely still, all wearing bowlers and
carrying briefcases, and all smoking little grey cigars. But the  smoke from
the cigars didn't disperse in  the normal way.  Here, where the  air  seemed
made  of  glass and was never disturbed by a breath  of wind, the threads of
smoke clung like cobwebs, creeping along the streets and up the walls of the
snow-white  houses,  festooning  each  ledge  and  cornice  and  windowsill,
condensing  into a noisome,  bluish-green fog bank that billowed ever higher
until it encircled Nowhere House like a wall.
     Momo took off the glasses and looked at Professor Hora inquiringly.
     'Have you seen enough?' he asked. 'Then let me have the  glasses back.'
He  put them  on  again.  'You asked if  the men in  grey could  make  me do
something  against  my  will,'  he  went  on.  'Well, they  can't get at  me
personally, as you know, but  they  could subject the  world  to an evil far
worse than any they've inflicted on it so far. That's how they hope to force
my hand.'
     Momo was  appalled. 'What  could be worse than stealing people's time?'
she asked. 'I allot people their share of time,' the professor explained.
     213
     'The men  in grey can't  stop  that.  They  can't intercept the time  I
distribute, but they can poison it.'
     'They can poison it?' Œ®£«® repeated, more appalled still.
     The professor nodded. 'Yes, with the smoke from their cigars. Have  you
ever  seen one without his little grey cigar? Of course not, because without
it he couldn't exist.'
     'What kind of cigars are they?' Momo asked.
     'You remember where the hour-lilies were growing?' Professor Hora said.
'I told you then that everyone has a place like that, because everyone has a
heart. If people allow the men  in grey to gain a foothold  there,  more and
more  of  their hour-lilies  get  stolen. But  hour-lilies  plucked  from  a
person's heart can't die, because they've never really  withered. They can't
live,  either, because they've been parted  from their  rightful owner. They
strive with  every  fibre of their being to return to the person they belong
to.'
     Momo was listening with bated breath.
     'If  you think  I know  everything, Momo, you're wrong. Some evils  are
wrapped in mystery. I've  no idea where  the men in  grey  keep their stolen
hour-lilies.  I  only know that they preserve  the blossoms by freezing them
till they're as hard as glass goblets. Somewhere deep underground there must
be a gigantic cold store.'
     Memo's cheeks began to burn with indignation.
     'And that's  where the men in grey draw their  supplies from. They pull
off the hour-lilies' petals, let them wither till they're dried up and grey,
and roll  their little cigars out of them. The petals still contain remnants
of  life, even then,  but living time is harmful to the men in grey, so they
light  the cigars and smoke  them.  Only when time has been  converted  into
smoke is it well and  truly dead. That's what keeps the men in grey "alive":
dead human time.'
     Momo had risen to her feet. 'Oh,' she exclaimed, 'to think of all those
poor flowers, all that dead time . ..'
     'Yes, the wall they're erecting around this house is built of
     214
     ucad  time. There's still enough open sky  above  for me to send people
their  time in good condition, but once that pall of  smoke closes over  our
heads, every hour  I send them will  be contaminated with the  time-thieves'
poison. When they absorb it, it'll make them ill.'
     Momo stared at the professor  uncomprehendingly. 'What kind of  illness
is it?' she asked in a low voice.
     'A fatal illness, though you scarcely notice  it at first. One day, you
don't feel  like doing  anything. -Nothing  interests you, everything  bores
you. Far from wearing  off, your boredom persists and gets worse, day by day
and  week by week. You feel more and more bad-tempered, more and more  empty
inside, more and  more dissatisfied with  yourself and the world in general.
Then even that  feeling wears off, and you don't feel anything any more. You
become completely indifferent to  what goes on around  you. Joy and  sorrow,
anger and excitement are things of the past. You forget how to laugh and cry
- you're  cold inside  and incapable of loving anything or anyone. Once  you
reach that  stage, the  disease  is  incurable. There's  no  going back. You
bustle around with a blank, grey face,  just like the men in grey themselves
-indeed,  you've joined  their  ranks.  The disease has a name.  It's called
deadly tedium.'
     Momo shivered. 'You mean,' she said, 'unless you hand over all the time
there is, they'll turn people into creatures like themselves?'
     'Yes,' the professor replied.  'That's how  they hope  to bully me into
it.' He rose and turned away. 'I've waited till now for people to get rid of
those  pests.  They could have done so -after all, it was they  who  brought
them into existence in the lirst place - but I can't wait any longer. I must
do something,  •ind I can't do  it on my own.'  He looked  Momo in the  eye.
'Will you help me?' 'Yes,' she whispered. 'If  you do,  you'll be running an
incalculable risk. It will be
     215
     up to you wnerncr me wona oegins to live again or stands stili for ever
and a day. Are you really prepared to take that risk?'
     'Yes', Momo repeated, and this time her voice was firm.
     'In that case,' said the professor, 'listen carefully to what I'm going
to tell you, because you'll be all on your own. I won't be able to help you,
nor will anyone else.'
     Momo nodded, gazing at him intently.
     'I must  begin by telling you that I never sleep,' he said. 'If I dozed
off, time would stand still and the  world  would come  to  a stop. If there
were no more time, the men in grey would have none left to steal. They could
continue  to exist for a while by  using up  their  vast  reserves, but once
those had gone they would dissolve into thin air.'
     'Then the answer's simple, surely?' said Momo.
     'Not as simple as it  sounds, I'm afraid, or I wouldn't need your help.
The trouble is, if there were no more time I couldn't wake up again, and the
world would continue to stand still for all eternity. It  does, however, lie
within  my power  to  give  you - and you alone - an hour-lily. Only one, of
course, because only one ever blooms at a time. So, if time stopped all over
the world, you would still have one hour's grace.'
     'Then I could wake you,' said Momo.
     The professor shook his head. 'That would achieve nothing,  because the
men  in  grey have  far too much time  in reserve.  They would consume  very
little of it in an hour, so they'd still be there when the hour was  up. No,
Momo, the problem is a  great deal harder  than that. As soon as the men  in
grey notice  that  time has stopped -  and it won't take them long,  because
their supply of cigars will be interrupted -they'll lift the siege and  head
for their secret store. You must follow them and prevent  them from reaching
it. When their cigars  are finished, they'll be finished too. But then comes
what  may well turn out to be  the hardest part of all. Once the last of the
time-thieves has vanished,  you  must release every  stolen minute,  because
only when people get their time back
     216
     win  i  wane up and the world  come to life again. And all  this you'll
have to do within the space of a single hour.'
     Momo hadn't reckoned  with such a host of difficulties and dangers. She
stared at him helplessly.
     'Will  you try  all the  same?' the  professor  asked. 'It's  our  only
chance.'
     Momo  couldn't  bring  herself  to  speak,  she found  the prospect  so
daunting.  At that moment, Cassiopeia's shell  lit up. 'I'LL  COME  TOO,' it
signalled.
     Unlikely as  it seemed that the  tortoise could  be  of help, the words
conjured up a tiny ray of hope.  Momo felt  heartened  at the thought of not
being  entirely alone. Although  there were  no  rational grounds for such a
feeling,  it did at  least enable her  to  make up her mind. 'I'll try,' she
said resolutely.
     Professor ®£  gave her a  long look and started to smile. 'Many things
will prove easier  than you think. You've heard the music of the stars.  You
mustn't feel frightened.' He turned to the tortoise. 'So you want to go too,
do you?'
     'OF COURSE,' Cassiopeia spelled out. Then, 'SOMEONE  HAS  TO LOOK AFTER
HER.'  The  professor  and Momo  smiled  at each  other.  'Will she  get  an
hour-lily too?'  Momo asked. 'She doesn't need one,' the  professor replied,
gently  tickling the tortoise's  neck. 'Cassiopeia is a creature from beyond
the frontiers of time. She carries her own little supply of time inside her.
She could go on crawling across the face  of  the  earth even  if everything
else stood still for ever.'
     'Good,' said Momo, suddenly eager to get on with the job. 'What happens
next?'
     'Now,' said  the professor,  'we  say goodbye.' Momo felt a lump in her
throat.  'Won't we ever see  each other again?' she asked softly. 'Of course
we will,' he told her, 'and until that day comes,
     217
     every  hour  of  your life will bring  you  my love.  We'll  always  be
friends, won't we?'
     Momo nodded.
     'I'm  going now,' the professor went  on, 'but you mustn't follow me or
ask where I'm  going.  My sleep is  no  ordinary  sleep,  and I'd sooner you
weren't  there. One  last thing:  as soon as  I'm gone, you  must  open both
doors,  the little one with my name on it and the big bronze one that  leads
into Never Lane. Once time has stopped,  everything will stand still  and no
power on earth  will be able to budge those doors.  Have  you understood and
memorized all I've told you?'
     'Yes,' said Momo, 'but how shall I know when time has stopped?'
     'You'll know, never fear.'
     They both stood up. Professor Hora gently stroked Momo's tousled mop of
hair. 'Goodbye, Momo,' he said, 'and thank you for listening so carefully.'
     'I'm  going to tell everyone  about  you,' she replied, 'when it's  all
over.'
     From one moment to the next. Professor Hora  looked  as old as  he  had
when he carried her into the  golden dome - as old as  an  ancient  tree  or
primeval crag.
     Turning away,  he  walked swiftly  out of the little  room  whose walls
consisted  of  grandfather clocks. Momo heard  his footsteps fade until they
were indistinguishable from  the ticking of the countless clocks around her.
Their  incessant whirring and ticking  and chiming seemed to have  swallowed
him up.
     Momo  took Cassiopeia  in  her  arms  and held  her  tight.  Her  great
adventure had begun. There could be no turning back.
        TWENTY
     Pursuing the Pursuers
     Momo's first  step  was  to open the little door  with Professor Hora's
name on it. Then she sped along the corridor  lined with statues  and opened
the big bronze  front door. She had to exert all her strength because it was
so heavy.
     That done,  she ran back to the  great hall and waited, with Cassiopeia
in her arms, to see what would happen.
     She didn't have to wait  long. There  was a  sudden jolt, but it didn't
actually  shake the  ground.  It  was  a  timequake,  so to  speak,  not  an
earthquake. No  words could describe the sensation, which was accompanied by
a  sound such  as no human ear had ever heard before: a sigh that seemed  to
issue from the depths of the ages. And then it was over.
     Simultaneously,  the innumerable clocks stopped  ticking,  whirring and
chiming. Pendulums came to  a sudden halt  and stayed put at odd angles. The
silence that fell was more profound than any that had  ever reigned  before.
Time itself was standing still.
     As for Momo, she became aware that  she was  clasping  the  stem  of an
hour-lily of exceptional size and beauty. She hadn't felt anyone put it into
her hand. It simply appeared, as if it had always been there.
     Gingerly, Momo took  a step. Sure enough, she could move  as easily  as
ever. The remains of breakfast were still on  the table. She sat down on one
of the little armchairs, but the seat was as hard as marble and didn't yield
an inch. There was a mouthful of chocolate left in her cup, but the cup
     219
     wouldn't move either. She  tried dipping  her fingers in the dregs, but
they were as hard  as butterscotch.  So  was the honey,  and even the crumbs
were  stuck fast to  the plates. Now that time had stopped, everything  else
was immovable too.
     Cassiopeia  had started to fidget. Looking down, Momo saw some words on
her shell. 'YOU'RE WASTING TIME!' she read.
     Heavens alive, so she  was! Momo pulled  herself together. She  hurried
through the forest of clocks to the little door, squeezed through it and ran
along the passage  to the  front door. She  peered  out, then darted back in
panic.  Her  heart began  to thump  furiously.  Far from  running away,  the
time-thieves were streaming towards  her up Never Lane. They could  do that,
of  course, now time  had ceased to flow  in reverse there,  but she  hadn't
allowed for the possibility.
     She raced  back to the great  hall and, still clutching Cassiopeia, hid
behind  a massive  grandfather clock. 'That's  a  good start,'  she muttered
ruefully.
     Then she heard the men in grey  come  marching along the corridor. They
squeezed through the little door, one after another, until a whole crowd  of
them had assembled inside.
     'So  this is our new  headquarters,' said one, surveying the vast room.
'Very impressive.'
     'That girl  let us in,' said  another grey voice. 'I distinctly saw her
open the door, the sensible  child. I wonder how  she  managed to get around
the old man.'
     'If you ask  me,' said a third voice, 'the old man's knuckled under. If
time has stopped flowing in Never Lane, it can only mean he switched  it off
himself.  In other  words,  he  knows he's  beaten.  Where  is he,  the  old
mischief-maker? Let's finish him off!'
     The  men  in grey  were looking around when one  of them  had a  sudden
thought. His  voice  sounded  even  greyer,  if  possible,  than  the  rest.
'Something's wrong, gentlemen,' he
     220
     said. 'The clocks - look at the clocks! Every one of them has  stopped,
even this hourglass here.'
     .  'I  suppose  he  must  have  stopped   them,'  another  voice   said
uncertainly.
     'You can't stop an hourglass,' the first man in grey retorted. 'See for
yourselves, gentlemen - the  sand's suspended  in mid-air  and the hourglass
itself won't budge! What does it mean?'
     He  was still speaking when footsteps came  pounding along the corridor
and  yet another man in grey squeezed through the little door, gesticulating
wildly. 'We've  just had word from  our agents in the  city,'  he announced.
'Their  cars have stopped,  and  so has  everything  else - the world's at a
standstill.  There isn't  a  microsecond  of time to  be  had anywhere.  Our
supplies have been cut off. Time has ceased to exist.  Hora has switched  it
off!'
     There  was  a  deathly  hush.  Then  someone  said, 'What do you  mean,
switched it off? What'll become of us  when we've finished the  cigars we're
smoking?'
     'What'll  become of us?' shouted someone else. 'You know that perfectly
well. This is disastrous, gentlemen!'
     They all began to shout at once. 'Hora's planning to destroy us!' - 'We
must lift the siege at once!'  - 'We  must  try to  reach the time store!' -
'Without our  cars?  We'll never make it in time!' - 'My cigar won't last me
more than twenty-seven minutes!'  - 'Mine will last me forty-eight!' - 'Give
it to me, then!' - 'Are you crazy? It's every man for himself!'
     There was a concerted rush for the little  door. From her hiding place,
Momo saw panic-stricken grey figures trying to squeeze through it, jostling,
scuffling  and swapping punches in a desperate  attempt  to  save their grey
lives. The rush  became a violent melee  as they knocked each  other's  hats
off, wrestled with each other, snatched the cigars from each other's mouths.
And whenever  they lost  their cigars, they  seemed  to lose  every ounce of
strength as well. They stood
     221
     there   with  their  arms  outstretched  and  a  plaintive,   terrified
expression  on  their  faces,  growing more  and more transparent until they
finally vanished. Nothing remained of them, not even their hats.
     In the end, only three  men  in grey were left. They ducked through the
little door, one after the other, and scuttled off down the passage.
     Momo, with Cassiopeia under one arm and her free hand tightly clutching
the  hour-lily, ran  after them.  All now depended  on her  keeping  them in
sight.
     She saw, when she  emerged from the front door,  that  they had already
reached the  mouth of  Never  Lane.  More smoke-wreathed men  in  grey  were
standing there, talking and gesticulating excitedly. As soon  as they caught
sight of the three fugitives  from  Nowhere House, they started running too.
Others joined  in the stampede, and soon  the  whole  army had taken  to its
heels.  'More haste  less speed' no longer applied, of course, now that time
was at a standstill. An endless column of grey figures streamed  towards the
city through the strange, dreamlike district  with its snow-white houses and
oddly assorted shadows, past the  monument resembling an egg, until it  came
to the grey, shabby tenements  inhabited by people who  lived on the edge of
time. Here too, though, everything was still and silent.
     What followed was a  chase in reverse - a chase in which countless grey
figures were  pursued through the city, at  a discreet  distance behind  the
last of the stragglers, by a girl  with a flower  in her hand and a tortoise
under her arm.
     But how strange the city looked  now!  Long lines  of  cars choked  the
streets with the fumes from their exhausts solidified, and behind each wheel
sat a motionless  driver, one hand frozen on horn or gear  lever.  Momo even
caught  sight of  one driver  who had been immobilized while  glaring at his
neigh-
     222
     hour and meamngtully tapping his forehead. Cyclists were poised at road
junctions with their arms extended, signalling right or left, and the people
thronging the pavements resembled waxwork figures.
     Traffic policemen stood at crossroads, whistles in their mouths, caught
in the act of waving the  traffic on. A  flock of pigeons hovered motionless
above  a  square, and  high overhead,  as though painted on  the sky, was an
equally motionless  aeroplane. The water  in the fountains  might
