But Harry, Mobius seemed shocked, I'm no vampire! Your mind is your ow n, private and inviolable, and - 'But not for much longer,' Harry cut him off. 'Not if you turn me down!'

And desperately now: 'August Ferdinand, I have to go up against something ent irely monstrous, and I need all the help I can get. But it's not just for me, it's for everyone and everything. For you see, if I lose this one, then my e nemy gets it all - even the Mobius Continuum itself! Believe me, I'm not exag gerating. If you can't open those doors in my head, he will. And . . . and .

. . and after that -' Yes?

' - After that, I just don't know.' Mobius was silent for a moment, and the n: That serious, eh?

That serious, yes.'

But Harry, all your secrets are in there, your ambitions, your most private thoughts.

'Also my desires, my vices, my sins. But it's no peep-show, August. You don't have to look where you don't want to.'

The other sighed his acquiescence. Very well. How do we go about it?

Harry was eager now. 'August Ferdinand, you're the one man among all th e dead who can go anywhere -literally anywhere - in three-dimensional s.p.a.ce . You've been out to the stars, down to the bed of the deepest ocean. Throu gh your knowledge of the Mobius Continuum, you've thrown off the fetters of the grave. So ... how we go about it is simple. I hope so, anyway. I'm goi ng to clear my mind and drift in sleep, and simply invite you in. I'm going to say: Mobius, come into my mind. Enter, of your own free will, and do wh atever is necessary to . . .'

AHHH! came the black, gurglingly glutinous, utterly overpowe ring voice of Janos Ferenczy in Harry's mind. BUT SUCH AN ELOQUE NT INVITATION. NEVER LET IT BE SAID THAT I WAS THE ONE TO REFUSE.

YOU!.

Mobius and his deadspeak were swept aside on the instant. Harry, paralyse d, could do nothing. He felt the Ferenczy step inside his head as a fish feel s the lamprey's clamps in its gill, and was likewise impotent to stop it. It was as if some nameless slug had oozed in through his ear to eat his brain, a nd was now stretching itself luxuriously before commencing the feast. He trie d to bring down the shutters of his mind but they were stuck, effortlessly he ld open by the invader.

OH? said Janos, as yet feeling his way, enjoying the horror of his host. AND DID I FEEL YOU CRINGE JUST THEN?

COULD IT BE THAT YOU ATTEMPTED TO EVICT ME? AND WAS THAT.

A MEASURE OF YOUR STRENGTH? IF SO, THEN I'VE PRECIOUS LIT.

TLE TO FEAR HERE! BUT FOR SHAME, HARRY KEOGH! WOULD YOU I.

NVITE ME IN AND AS QUICKLY THROW ME OUT? AND WHAT SORT OF.

A HOST ARE YOU?.

'My . . . invitation . . . wasn't to you!' Harry forced his brain into gear, tried to remind himself that this was just another vampire. Janos settled on the thought like a vulture to carrion: I WAS NOT INVITED? BUT YOUR MIND WAS OPEN AS A Wh.o.r.e.

'S CROTCH - AND JUST AS TEMPTING!.

Something of Harry's horror receded; he tightened his grip on himself, fo rced his feverish mind into what he hoped was a defensive stance. But he coul d almost smell the vampire's vile breath and feel his stealthy tread in the c orridors of his most secret being.

AND STILL YOU ACCUSE ME OF STENCHES! the invader laug hed. WHAT WAS IT YOU LIKENED ME TO THE LAST TIME? A DEAD PIG? YOU OF ALL PEOPLE SHOULD KNOW BETTER, FOR I AM UNDEA.

D . . .

Suddenly Harry was cool. He had felt stifled but now it was as if someone had thrown open a window to blow out all the cobwebs of his mind. He filled his lungs with the rush of this weird, conjectural ether and felt stronger fo r it. And from a far more buoyant if mysterious viewpoint, he wondered at the audacity of the vampire that he should feel so safe and secure as to be able to just . . . just walk in here.

All of these most recent thoughts were guarded, so that Janos took Harry's silence as an indication of sheer terror. AND SO TH IS IS THE MIGHTY NECROSCOPE, said the vampire. AND HOW DOES IT FE EL TO HAVE MY 'FILTHY LEECH'S MIND' IN YOUR HEAD, HARRY?.

Harry continued to guard his thoughts. It wasn't difficult; it was like deadspeak, where with a small effort of concentration the dead heard only wh at he required them to hear. And again he felt a peculiar surge of confidenc e which was surely well out of place here. For, asleep and dreaming, he coul dn't exert half as much control over his mind as when he was awake. However true that might be, still he sensed that Janos was becoming just a fraction more cautious.

YOU KNOW OF COURSE THAT I CAN BEND YOU TO MY WILL JUST AS.

I BENT - AND BROKE - THAT FOOL JORDAN? But was Janos stating a fact, or was he asking himself a question?

'Keep telling yourself that,' said Harry, without emotion. 'But remember: you entered of your own free will.'

WHAT? And now there was a ragged, worried edge to Janos's thoughts. As if for the first time he might be weighing the issues and considering his p osition here.

And in the back of Harry's mind, unsuspected by Janos, it was as if he he ard Faethor advising him again, as he had in the ruins of his house outside P loiesti: Instead of shrinking back from him when you sense him near, seek him out ! He would enter your mind? Enter his! He will expect you to be afraid; be b old! He will threaten; brush all such threats aside and strike! But above al l else, do not let his evil weaken you. And, finally: There may be more to y our mind than even you suspect, Harry . . .

Janos was beginning to think so too. THIS MIND OF YOURS IS ... DIFFERENT FROM THE MINDS OF OTHER MEN. IT WILL GIVE.

ME GREAT PLEASURE TO EXPLORE IT. AND IT WILL GIVE YOU GREA.

T PAIN!.

'Well, at least you have the vanity of the Wamphyri,' said Harry. 'But wha t is vanity without the means to match it?'

YOU KNOW US ... WELL, said Janos, edgier than ever. PERHAPS T OO WELL.

'Having second thoughts, my son?'

And again, but angrily: WHAT?!

'Come now, not so nervous. I speak more as an uncle than a true father.

But it's a fact I do have a son of my own. Except, of course, he is Wamphy ri! But see, now I sense your trembling. What, you afraid? How so? For afte r all you have my measure. Have you not invaded my mind? Where is my resist ance? With what may I resist? Here you are inside the castle of my very bei ng. Ah, but there are castles and there are castles - and some are easier t o get into than they are to get out of!' And at last Harry brought the shut ters of his mind crashing down.

Janos was confused; this was no mere man; it was as if he talked to ... s omething far greater than a man. In his panic, so the vampire became vicious: THESE PUNY BARRIERS YOU HAVE ERECTED ... I AM SURR.

OUNDED BY DOORS. BUT I HAVE THE STRENGTH TO BEAT THEM.

ALL DOWN, INDEED TO TEAR THEM FROM THEIR HINGES!.

Harry heard him, but he also heard this: When he yawns his great jaws at you, go in through them, for he's softer o n the inside!

'Beat them all down, then,' he answered. 'Tear them from their hinges - if you dare!'

Janos dared. He ran through Harry's mind shattering every barrier the N ecroscope could put in his way, tearing down the shutters and screens on hi s Innermost Being. All Harry's past was there, his loves and hates, his hopes and aspirations, and all trampled under as the vampire marauded through previously secret corridors of id. In any one of these places the monster m ight pause a while, play, cause Harry to laugh, cry, scream - or die. But r ealizing now that indeed he had Harry's measure, he didn't pause but rampag ed. And: WHAT? WHAT? he finally laughed, as he came to a place mo re heavily fortified than all the rest put together. WHY, IT CAN ONLY BE THE VERY TREASURE HOUSE! AND WHAT MARVELLOUS SE.

CRETS ARE STORED HERE, HARRY KEOGH? ARE THESE THE VAULTS OF.

YOUR TALENTS?.

And before Harry could answer - if he would answer -Janos had wrenched two of the doors open.

Beyond one of them was the ultimate NOTHING, so that in a single momen t Janos found himself teetering on the threshold of the Mobius Continuum.

And behind the other . . . was Faethor Ferenczy, crouching there where he directed Harry's game, and now inspired Janos's uttermost terror!

The invader reared back - from Faethor, who had now emerged more fully from his hiding place and was frantically trying to push him through the doorway to eternity, and from the Mobius Continuum both - and grunted his shock, astonishment and total disbelief. For within a mainly human ident.i.t y he had stumbled across not only an Unknowable and terrifying concept, bu t also the entirely monstrous and alien mind of his own long-dead father!

Terror galvanized him: he tore himself free from Faethor, gasped a stre am of semi-coherent obscenities at him, and fled. He broke out of Harry's i d, was gone in a moment. He had done no real damage, and the Necroscope gue ssed that he'd never dare try it again. But - 'Faethor!' Harry growled, his mental voice as grim and wrenching as an old chalk on a new blackboard - his own voice now, no longer influenced or guided by the mind of his secret tenant. And again: 'Faethor!'

There was no answer, except perhaps a far, faint chuckle, like oily bubbl es bursting on a lake of pitch. Or perhaps the furtive whir of bat-wings, ech oing from the deepest, darkest cave.

'Oh, you b.a.s.t.a.r.d . . . you liar!' Harry howled. 'You're in here! You have b een right from the moment I let you in! But I can find you, throw you out . . .

And at last: No need, my son, came Faethor's distant, diseased whisper. The first battle is fought and won; the sun rises; I . . . get... me ... gone!

After that: Harry surfaced from his dreams slow and cold, so that the sweat was dry on him by the time he was fully awake and Darcy Clarke came knocking on his door mumbling about breakfast. By then, too, Harry believe d he'd worked out how he was going to play the rest of it At 8:15 Rhodes Town was only just awake, but already Harry was down on a pier in Mandraki harbour to see his friends off. Darcy and Manolis wave d several times as their boat pulled out onto the incredible blue millpond of the Aegean, but he didn't wave back. He simply nodded and watched them out of sight, and silently wished them luck.

Then he drove over to the beach at Kritika and swam for an hour before re turning to the hotel and showering. Even after furiously towelling himself dr y, and despite the fact that it was at least seventy-five degrees out in the sun, he was still cold. The coldness he felt had nothing to do with the outsi de temperature. It came from inside.

Harry's bed had been freshly made; he lay on it with his hands behind his head and thought a while, slowly emptying his mind and letting himself drift . . .

. . . Then made a stab at Faethor!

And caught him there in his mind before he could wriggle down out of sig ht. Faethor, right there in his mind, and the time just a little after 10:30 , and a scorching sun standing high in the sky. So much for the sun as a det errent. Harry should have known: ghosts don't burn. It might give Faethor a few bad dreams but it couldn't physically hurt him because there was nothing physical left of him. Any of Harry's dead friends could have told him that much.

'You old devil!' he said, but coldly, for he wasn't name-calling, just stat ing a fact. 'You old b.a.s.t.a.r.d, you old liar. So just like Thibor fastened on Dra gosani, you're thinking of latching on to me, eh?'

Thinking of it? Faethor came into the open, and Harry could feel him as cl ose as if he stood right there at his bedside. Fait accompli, Harry. Get used to it.

Harry shook his head and grinned mirthlessly. 'I will be rid of you,' he sai d. 'Believe me, Faethor, I'll be rid of you, even if it means getting rid of mys elf.'

Suicide? Faethor tut-tutted. No, not you, Harry. Why, you are tenacious a s the ones you hunt down and destroy! You will not kill yourself while there'

s still a chance to kill another one of them.

'Another one of you, you mean? But you could be wrong, Faethor. Me, I'm only human. I'd die pretty easily. A bullet through my brain, like Trevor Jo rdan . . . I wouldn't even know about it. Believe me, it's tempting.'

I see no real notion of suicide in your thoughts, Faethor shrugged, so why pretend? Do you think I feel threatened? How can you threaten me, Harry ? I'm already dead!

'But in me you have life, right? Listen and I'll tell you something: you r eally don't know what's in my thoughts. I can hide them, even from you. It's d eadspeak; that's how I learned to do it; by keeping back my thoughts from the dead. I did it then so as not to hurt them, but I can just as easily use it th e other way.'

For a moment - the merest tick of the clock - Harry felt Faethor waverin g. And he nodded knowingly. 'See? I know what's on your mind, old devil. But do you know what's on mine, if I hide it from you . . . so?'

Deep in the psyche of Harry, the Father of Vampires felt himself surrounde d by nothing. It fell on him like a blanket, as if to smother him. It was as i f he were back in the earth near Ploiesti, where his evil fats had been render ed down the night Ladislau Giresci took his life.

'You see,' Harry told him, letting the light of his thoughts shine in again, '

I can shut you out.'

Not out, Harry. You can only shut me off. But the moment you relax I'll b e back.

'Always?'

For a moment Faethor was silent. Then: No, for we made a bargain. And so long as you hold to it, then so shall I. When Janos is no more, then you'll be rid of me.

'You swear it?'

Upon my soul! Faethor gurgled like a night-dark swamp, and smiled an i mmaterial smile.

It was the natural sarcasm of the vampire, but Harry only said: Til hold yo u to that.' And his mental voice was cold as the s.p.a.ces between the stars. 'Jus t remember, Faethor, I'll hold you to it . . .'

Manolis handled the boat. It had a small cabin and a large engine, and left a wake like low white walls melting back into the blue. Always in sigh t of land, they had rounded Cape Koumbourno and outpaced the water-skiers o ff Kritika Beach before Harry had even hit the water there. By 9:00 a.m. th ey had pa.s.sed Cape Minas, and with the mainland lying to port were heading for Alimnia. Darcy had thought he might have trouble with his stomach, but the sea was like gla.s.s and with the wind in his face ... he might easily be enjoying an expensive holiday. That is, if he wasn't perfectly sure he was heading for horror.

Around 10:00 a pair of dolphins played chicken across the prow of the b oat where it sliced the water; by which time they'd pa.s.sed between the almo st barren rocks of Alimnia and Makri, and Halki (which Manolis insisted sho uld be 'Khalki', for the chalky sh.e.l.ls it was named after) had swum into vi ew.

Fifteen minutes later they were into the harbour and tied up, and Manoli s was chatting with a pair of weathered fishermen where they mended their ne ts. While he made his apparently casual inquiries, Darcy bought a map from a tiny box of a shop right on the waterfront and studied what he could of the island's layout. There wasn't a great deal to study. The island was a big rock something less than eight by four miles, with the long axis lying east to west. Looking west a mile or two, mountain crest s stood wild and desolate where the island's one road of any description wan dered apparently aimlessly. And Darcy knew that his and Manolis's destinatio n lay way up there, in the heights at the end of that road. He didn't need t he map to know it: his talent had been telling him ever since he stepped fro m the boat to dry land.

Eventually, done with talking to the fishermen, Manolis joined him. 'No tr ansport,' he said. 'It is maybe two miles, then the climbing, and of course we will be carrying our - how do you say - picnic basket? It looks like a long h ot walk, my friend, and all of it uphill.'

Darcy looked around. 'Well, what's that,' he said, 'if not transport?' A t hree-wheeled device, clattering like a steam-engine and pulling a four-wheel c art, came clanking out of a narrow street to park in the 'centre of town', tha t being the waterfront with its bars and tavernas.

The driver was a slim, small Greek of about forty-five; he got down fr om his driver's seat and went into a grocery store. Darcy and Manolis were waiting for him when he came out. His name was Nikos; he owned a taverna and rooms on a beach across the bottleneck of the promontory behind the to wn; business was slow right now and he could run them up to the end of the road for a small remuneration. When Manolis mentioned a sum of fifteen hu ndred drachmae his eyes lit up like lamps, and after he'd collected his fi sh, groceries, booze and other items for the taverna, then they were off.

Sitting in the back of the cart had to be better than walking - but not m uch better. On the way Nikos stopped to unload his purchases at the taverna, and to open a couple of bottles of beer for his pa.s.sengers, and then the jour ney continued.

After a little while and when he'd adjusted his position against the joltin g, Darcy took a swig of his beer and said: 'What did you find out?'

'There are two of them,' Manolis answered. 'They come down at evening to buy meat - red meat, no fish - and maybe drink a bottle of wine. They stay together, don't talk much, do their own cooking up at the site . . . if they cook!' He shrugged and looked narrow-eyed at Darcy. 'They work mainly at ni ght; when the wind is in the right direction the villagers occasionally hear them blasting. Nothing big, just small charges to shift the rocks and the r ubble. During the day . . . they are not seen to do too much. They laze arou nd in the caves up there.'

'What about the tourists?' Darcy inquired. 'Wouldn't they be a nuisance?

And how come Lazarides - or Janos - gets away with it? I mean, digging in t hese ruins? Is your government crazy or something? This is ... it's history!'

Again Manolis's shrug. 'The Vrykoulakas apparently has his friends. Anywa y, they are not actually digging in the ruins. Beyond the castle where it sits up on the crest, the cliff falls away very steeply. Down there are ledges, and caves. This is where they are digging. The villagers think they are the c razy men. What, treasure up there? Dust and rocks, and that's all.'

Darcy nodded. 'But Janos knows better, eh? Let's face it, if he buried it, he should know where to dig for it!'

Manolis agreed. 'As for the tourists: there are maybe thirty of them righ t now. They spend their time in the tavernas, on the beach, lazing around. Th ey are on holiday, right? Some climb up to the castle, but never down the oth er side. And never at night.'

'It feels weird,' said Darcy, after a while.

'What does?'

'We're going up there to kill these things.'

'Right,' Manolis answered. 'But only if it's necessary. I mean, only if they are things!'

Darcy gave an involuntary shudder and glanced at the long, narrow wicker basket which lay between them. Inside it were spearguns, wooden stakes, Har ry Keogh's crossbow, and a gallon of petrol in a plastic container. 'Oh, the y are,' he said then, and offered a curt nod. 'You can believe me, they are . . .'.

Fifteen minutes later Nikos brought his vehicle to a halt in a rising re-e ntry. To the left, pathways which were little more than goat tracks led steepl y up through the ruined streets of an ancient, long-deserted hill town; above the ruins stood a gleaming white monastery, apparently still in use; and highe r still, on the almost sheer crown of the mountain itself - ' - The castle!' Manolis breathed.
