He looked out and down from his vantage point in a clump of pines on the north face of the mountainside where it wound back into the gorge, and trained his binoculars on the four men who climbed carefully along the last hundred yards of boulder- and scree-littered ledge weathered into the sheer cliff which formed the south face. They were less than three hundred yards away, but Dolgikh used his binoculars anyway.

He enjoyed close-up the strain in their sweating faces, imagined he could feel their aching muscles, tried to picture their thoughts as they headed one last time for the old creeper-grown ruins up there where the ravine bottle-necked and the stream rushed and gurgled unseen in the depths of the gorge. They'd be congratulating themselves that their quest — their mission — was almost concluded; ah, but they could hardly imagine that they themselves were also at an end!

This was the part that Dolgikh was going to enjoy:

bringing them to their conclusion, and letting them know that he was their executioner.

Most of the time the four moved in clear light, free of shadows: Krakovitch and his man, the British esper, and the big construction boss. But where the cliff overhung, there they merged with brown and green shade and black darkness. Dolgikh squinted into the sky. The sun was well past its zenith, sinking slowly beyond the looming mass of the Carpathians. In just two more hours it would be twilight, the Carpathian twilight, when the sun would abruptly slip down behind the peaks and ridges. And that was when the ‘accident' would happen.

He trained his binoculars on them again. The huge Russian foreman carried a haversack with its strap across one shoulder. A T-shaped metal handle protruded: the firing box for gelignite charges. Dolgikh nodded to himself. Earlier in the day he'd watched them lay charges in and around the old ruins; now they were going to blow the place and whatever it contained — a fabulous weapon, according to that twisted dwarf Ivan Gerenko — to hell! So they thought, but that was what Dolgikh was here to prevent.

He put his binoculars away, waited impatiently until they were safely off the ledge and into the woods of the overgrown slope beyond, then quickly moved in pursuit —for the last time. The cat and mouse game was over and it was time for the kill. They were out of sight in the-trees now, with perhaps a mile to go to the ruins, and so Dolgikh must make haste.

He checked his blunt, blued-steel, standard issue Malatukov automatic, shoved home the clip of snub-nosed rounds and reholstered the heavy weapon under his arm. Then he stepped out from cover. Directly opposite his position, across the narrow gorge, the new road came to an abrupt end. This was the point at which someone had decided it wouldn't be cost effective to proceed further. Rubble from the blasted cliff filled the depression, forming a dam for the mountain stream. A small lake lay smooth as a mirror behind it. Beneath the dam the water had forced a route, erupting in a torrent where the much reduced stream continued its course down towards the plain.

Dolgikh scrambled down to the jumbled debris which formed the bridge of the dam and nimbly made his way across and up on to the road. A minute more and he'd left the tarmac behind for the narrow, treacherous surface of the scree-littered ledge. And without further pause he followed in the tracks of his quarry. As he went, he thought back on the events of the day.

This morning he'd followed them when they first came up here. Finding their car parked on the road, he'd hidden his Fiat in a dense clump of bushes and tracked them on foot along this very ledge. Then, at the apex of the gorge where the two sides almost came together, they'd entered crumbling old ruins and searched through them. Dolgikh had observed, keeping well back. For maybe two hours they'd busied themselves digging in the ruins. By the time they were ready to leave they all seemed much subdued. Dolgikh didn't know what they'd found, or failed to find, but in any case he'd been told that it was probably dangerous and warned to steer clear.

Seeing them about to leave, he'd quickly hurried back to his car, waited for them to show up. And in passing, so as to be on the safe side, he'd fitted their vehicle with a magnetic bug. They'd driven back into Kolomyya then, with Dolgikh close behind but keeping just out of sight. He'd almost caught up with them where they stopped, half-way back along the new road, to talk with a party of gypsies in their encampment. But in a few minutes they'd been on their way again, and still they hadn't seen him.

Kolomyya was a railhead and meeting point for four tracks, from Khust, Ivano-Frankovsk, Chernovtsy and Gorodenka; every other building seemed to be a warehouse or storage depot. It wasn't hard to find one's way about; the industrial and commercial sides of the town were distinctly separate. The four men Dolgikh followed had driven to the town's main telephone exchange, parked outside and gone in.

Dolgikh parked his Fiat, stopped a passerby and asked about public call boxes. ‘Three!' the man told him, obviously disgusted. ‘Only three public telephones in a town as big as this! And all of them constantly in use. So if you're in a hurry you'd best make your call here, at the exchange. They'll put you through quick as a flash.'

In about ten minutes Krakovitch and his party had left the exchange, got into their car and driven off. Their tracker had been torn two ways: to follow them, or find out who they'd contacted and why. Since their car was bugged and he could always find them later, he'd decided on the latter course. Inside the small but busy exchange he'd wasted no time but asked for the manager. His KGB ID had guaranteed immediate co-operation. It turned out that Krakovitch had called Moscow — but not a number Dolgikh was familiar with. It seemed that the head of E-Branch had required higher authorisation for something or other; there had been some talk of blasting, and the big man in overalls had been very much involved. Krakovitch had allowed him also to use the phone. That was as much as anyone at the exchange knew of the matter. Dolgikh had then asked to be put through to Gerenko at the Château Bronnitsy, to whom he'd passed on all that he had learned.

At first Gerenko had seemed confused, but then:

‘They're working directly through Brezhnev's contact!' he'd snapped. ‘Not through me. Which can only mean that they suspect! Theo, make sure you get them all. Yes, including that construction foreman. And when it's done let me know at once.'

Tracking the bug he'd planted, Dolgikh had arrived at the depot of a local civil engineering firm in the town just in time to see Gulharov and Volkonsky loading a box of explosives into the boot of their car while Krakovitch and Quint looked on. Obviously the big Russian foreman was now a member of their team. Equally obvious, their contact in Moscow had cleared the use of materials for blasting. While Dolgikh still did not know what they intended to destroy, he did have an idea where it was. And what was more, that was as good a place as any for them to die.

While Theo Dolgikh was thinking back on the day's events, Carl Quint's mind was similarly engaged; and now that the broken fangs of Faethor Ferenczy's castle once more appeared through the dark, motionless pines, so his memory instinctively homed in on what he and Felix Krakovitch had found there during their first visit this morning. All four of them had been present, but only he and Krakovitch had known where to look.

The place had been almost magnetic in their psychically enhanced minds: the exact spot had drawn them like iron filings to a magnet. Except they were not filings, and it was not their intention to get stuck here. Quint remembered now how it had been .

‘Faethor's castle,' he'd breathed, as they came to a halt at the very rim of the ruins. ‘The mountain fastness of a vampire!' And in the eye of his mind he'd seen it again as it must have been a thousand years ago.
