In their own way, the three men inside the cable-car were as nearly stunned as Smith himself. The smiles had frozen on their faces and Christiansen's arm was still poised in mid-air where it had been arrested by the sound and the shock of Smith's landing on the cable-car roof. Carraciola, predictably, was the first to recover and react. He s.n.a.t.c.hed the Schmeisser from Christiansen and pointed it upwards.

The cable-car was now forty to fifty feet clear of the castle and the high wind was beginning to swing it, pendulum-like, across the sky. Smith, weakened by the impact of the fall, the pain in his hand and the loss of blood, hung on grimly and dizzily to the suspension bracket, his body athwart the roof of the car. He felt sick and exhausted and there seemed to be a mist in front of his eyes.

From shoulder to knee and only inches from his body a venomous burst of machine-pistol fire st.i.tched a pattern of holes in the cable-car roof: the mists cleared away from Smith's eyes more quickly than he would have believed possible. A Schmeisser magazine held far more sh.e.l.ls than that. They would wait a second or two to see if a falling body pa.s.sed any of the side windows -- with that violently swinging transverse movement it was virtually impossible for anyone to fall off over the leading or trailing ends of the car -- and if none came, then they would fire again. But where? What would be the next area of roof chosen for treatment? Would the gunman fire at random or to a systematic pattern? It was impossible to guess. Perhaps at that very moment the muzzle of the Schmeisser was only two inches from the middle of his spine. The very thought was enough to galvanise Smith into a quick roll that stretched him out over the line of holes that had just been made. It was unlikely that the gunman would fire in exactly the same place again, but even that was a gamble, the gunman might figure just as Smith was doing and traverse the same area again. But he wasn't figuring the same as Smith,,the next burst was three feet away towards the trailing end of the car.

Using the suspension bracket as support, Smith pulled himself to his feet until he was quite vertical, hanging on to the cable itself. This way, the possible target area was lessened by eighty per cent. Quickly, soundlessly, sliding his hands along the cable, he moved forward until he was standing at the very front of the car.

The cable-car's angle of arc through the sky was increasing with every swing of the pendulum. The purchase for his feet was minimal, all the strain came on his arms, and by far the greater part of that on his sound left arm. There was nothing smoothly progressive about the cable-car's sideways motion through the sky, it jumped and jerked and jarred and jolted like a Dervish dancer in the last seconds before total collapse. The strain on the left arm was intolerable, it felt as if the shoulder sinews were being torn apart: but shoulder sinews are reparable whereas the effects of a Schmeisser blast at point blank range were not. And it seemed, to Smith, highly unlikely that anybody would waste a burst on the particular spot where he was standing, the obvious position for any roof pa.s.senger who didn't want to be shaken off into the valley below was flat out on the roof with his arms wrapped for dear life round one of the suspension arm's support brackets.

His reasoning was correct. There were three more bursts, none of which came within feet of him, and then no more. Smith knew that he would have to return to the comparative security of the suspension arm and return there soon. He was nearly gone. The grip of his left hand on the cable was weakening, this forced him to strengthen the grip of his right hand and the resulting agony that travelled like an electric shock from his hand up his arm clear to the right hand side of his head served only to compound the weakness. He would have to get back, and he would have to get back now. He prayed that the Schmeisser's magazine was empty.

And then, and for another reason, he knew that he had no option but to go now: and he knew his prayer hadn't been answered. The leading door of the cable-car opened and a head and a hand appeared. The head was Carraciola's: the hand held the Schmeisser. Carraciola was looking upwards even as he leaned out and he saw Smith immediately: he leaned farther out still, swung the Schmeisser one-handedly until the stock rested on his shoulder and squeezed the trigger.

Under the circ.u.mstance accurate aiming was impossible.but at a distance of four feet accurate aiming was the last thing that mattered. Smith had already let go of the cable and was flinging himself convulsively backward when the first of the bullets ripped off his left hand epaulette. The second grazed his left shoulder, a brief burning sensation, but the rest of the burst pa.s.sed harmlessly over his head. He landed heavily, stretched out blindly, located and grasped one of the suspension arms and scuttled crab-like round the base of the suspension arm until he had it and what little pathetic cover it offered between him and Carraciola.

For Carraciola was coming after him and Carraciola was coming to make sure. He had the gun still in his hand and that gun could have very few sh.e.l.ls indeed left in the magazine: it would be no part of Carraciola's plan to waste any of those sh.e.l.ls. Even as Smith watched, Carraciola seemed to rise effortlessly three feet into the air -- a feat of levitation directly attributable to the powerful boost given him by Thomas and Christiansen -- jack-knifed forward at hip level and flattened his body on top of the cable-car roof: his legs.still dangled over the leading edge. A suicidal move, Smith thought in brief elation, Carraciola had made a fatal mistake: with neither hand hold nor purchase on that ice-coated roof, he must slide helplessly over the edge at the first jerk or jolt of the cable-car. But the elation was brief indeed for Carraciola had made no mistake. He had known what Smith hadn't: where to find a secure lodgement for his hand on the smooth expanse of that roof. Within seconds his scrabbling fingers had found safety -- a gash in the cable-car roof that had been torn open by one of the bursts from the Schmeisser. Carraciola's fingers hooked securely and he pulled himself forward until he was in a kneeling position, his toes hooked over the leading edge.

Smith reached up with his wounded hand and clawed:desperately for a grenade in the canvas bag slung over his left shoulder, at the same time pushing himself as far back as his anchoring left hand, clutched round a suspension bracket, would permit: at that range a grenade could do almost as much damage to himself as to Carraciola. His legs slid back until his feet projected over the trailing edge and he cried out in pain as a tremendous pressure, a bone-breaking, skin tearing pressure, was applied to his shins, half-way between knees and feet: someone had him by the ankles and that someone seemed determined to separate his feet from the rest of his body. Smith twisted his head round but all he could see was a pair of hands round his ankles, knuckles bone-white in the faint wash of moonlight. And no one man's weight, Smith realised, could have caused that agonising pain in his shins. His companion must had had him by the waist, whether to increase the pressure or to ensure his safety if Smith did slide over the end. The reasons were immaterial: the effect was the same. He tried to draw up his legs but with a pinning weight of well over 200 Ibs., any movement was quite impossible.

Smith risked a quick glance forward, but Carraciola hadn't moved, the cable-car was now half-way between the header station and the top pylon, the pendulum swing was at its maximum and Carraciola, still in his kneeling position, was hanging on for his life. Smith abandoned his attempt to reach for a grenade which could now serve no purpose whatsoever, unsheathed his knife, clasped the haft in the three good fingers of his right hand, twisted round and tried to strike at those hands that were causing him such excruciating agony. He couldn't get within fifteen inches of them.

His legs were breaking: his left arm was breaking: and his clenched grip on the support was slowly beginning to open. He had only seconds to go, Smith knew, and so he had nothing in the world to lose. He changed his grip on his knife, caught the tip of the blade between his broken thumb and the rest of his fingers, turned and threw the knife as powerfully and as accurately as his smashed hand and pain-dimmed eyes would permit. The stinging pain in his left ankle and the scream of pain from the trailing door were simultaneous: immediately, all the pressure on his ankles vanished: a second later, Christiansen, whom Thomas had managed to drag back inside the cable-car, was staring stupidly at the knife that transfixed his right wrist.

In that one instant Smith had won and he had lost. Or so it most surely seemed, for he was defenceless now: Carraciola had bided his time, calculated his chances and flung himself forward until he had reached the safety of the suspension bracket. Now he pulled himself slowly to his feet, his left arm round.the suspension arm itself, his left leg twined securely round one of the brackets. The Schmeisser pointed into Smith's face.

'Only one bullet left.' Carraciola's smile was almost pleasant. 'I had to make sure, you see.'

Perhaps he hadn't lost, Smith thought, perhaps he hadn't lost after all. Because of the pinioning effect of Christiansen's hands on his ankles he'd been unaware, until now, how much less difficult it had become to maintain position on that ice-sheathed roof, unaware how much the pendulum swaying of the cable-car had been reduced. And it seemed that, even now, Carraciola was still unaware of it, or, if the change of motion had registered with him, the reason for it had not. With a conscious effort of will Smith shifted his by now half-hypnotised gaze from the staring muzzle of the Schmeisser to a point just over Carraciola's shoulder. The suspension arm of the first pylon was less than twenty feet away.

'Too bad, Smith.' Carraciola steadied the barrel of his machine pistol. 'Comes to us all. Be seeing you.'

'Look behind you,' Smith said.

Carraciola half-smiled in weary disbelief that anyone should try that ancient one on him. Smith glanced briefly, a second time, over Carraciola's shoulder, winced and looked away. The disbelief vanished from Carraciola's face as if a light had been switched off. Some sixth sense or instantaneous flash of comprehension or just some sudden certainty of knowledge made him twist round and glance over his shoulder. He cried out in terror, the last sound he ever made. The steel suspension arm of the pylon smashed into his back. Both his back and inter-twined leg broke with a simultaneous crack that could have been heard a hundred yards away. One second later he was swept from the roof of the cable-car but by that time Carraciola was already dead. From the open rearward door of the car, Thomas and Christiansen, their shocked faces mirroring their stunned disbelief, watched the broken body tumbling down, into the darkness of the valley below.

Shaking like a man with the ague and moving like an old man in a dream, Smith slowly and painfully hauled himself forward until he was in a sitting position with an arm and leg wound round one of the after arms of the supporting bracket. Still in the same dream-like slow motion he lifted his head and gazed down the valley. The other cable-car, moving up-valley on its reciprocal course, had just pa.s.sed the lowermost of the three pylons. With luck, his own cable-car might be the first to arrive at the central pylon. With luck. Not, of course, that the question of luck entered into it any more: he had no options or alternatives left, he had to do what he had to do and luck was the last factor to be taken into consideration.

From his kit-bag Smith extracted two packets of plastic explosives and wedged them firmly between the roof of the car and the two after arms of the suspension bracket, making sure that the tear strip igniters were exposed and ready to hand. Then he braced himself, sitting upright, against the suspension bracket, using both arms and legs to anchor himself and prepared to sit it out once more as the cable-car, approaching midsection of its second lap between the first and central pylons, steadily increased its swaying angle of arc across the night sky.

It was foolish of him, he knew, to sit like that. The snow had momentarily stopped, and the full moon, riding palely in an empty sky, was flooding the valley with a wash of ghostly light. Sitting as he was he must, he realised, be clearly visible from either the castle or the lower station: but apart from the fact that he doubted whether concealment mattered any longer he knew there was nothing he could do about it, there wasn't the strength left in his one good arm to allow him to a.s.sume the p.r.o.ne spread-eagled position that he and Schaffer had used on the way up.

He wondered about Schaffer, wondered about him in a vaguely woolly detached way for which exhaustion, loss of blood and the bitter cold were almost equally responsible. He wondered about the others, too, about the elderly man and the girl perched on top of the header station roof, about the two men inside the cable-car: but Mary and Carnaby-Jones were helpless to do anything to help and the chances of the unarmed Thomas and Christiansen carrying out another rooftop sortie were remote indeed: Carraciola had carried a Schmeisser, and they had seen what had happened to Carraciola. Schaffer, it was Schaffer who mattered.

Schaffer was feeling even more vague and woolly than Smith, if for different reasons. He was waking, slowly and painfully, from a very bad dream and in this dream he could taste salt in his mouth and hear a soft urgent feminine voice calling his name, calling it over and over again. In normal times Schaffer would have been all for soft feminine voices, urgent or not, but he wished that this one would stop for it was He was awake, but this was one of those bad dreams which stayed with you even when you were awake. He could still taste salt -- the salt of blood -- his head still felt as if one incautious shake would have it rolling across the floor and that soft and urgent voice was still calling.

'Lieutenant Schaffer! Lieutenant Schaffer! Wake up, Lieutenant, wake up! Can you hear me?'

He'd heard that voice before, Schaffer decided, but he couldn't place it. It must have been a long time ago. He twisted his head to locate the source of the voice -- it seemed to come from above -- and the kaleidoscopic whirligig of colours were back in position again, revolving more quickly than ever. Head-shaking and head-twisting, Schaffer decided, were contra-indicated. He returned his head slowly to its original position, managed to get his knees under him, crawled forward in the direction of some dimly-seen piece of machinery and hauled himself shakily to his feet.

'Lieutenant! Lieutenant Schaffer! I'm up here.'

Schaffer turned and lifted his head in an almost grotesque slow motion and this time the whole universe of brightly dancing stars was reduced to the odd constellation or two. He recognised the voice from the distant past now, it was that of Mary Ellison, he even thought he recognised the pale strained face looking down from above, but he couldn't be sure, his eyes weren't focusing as they should. He wondered dizzily what the h.e.l.l she was doing up there staring down at him through what appeared to be the bars of a shattered sky-light: his mind, he dimly realised, was operating with all the speed and subtle fluency of a man swimming upstream against a river of black mola.s.ses.

'Are you -- are you all right?' Mary asked.

Schaffer considered this ridiculous question carefully. 'I expect I shall be,' he said with great restraint. 'What happened?'

'They hit you with your own gun.'

'That's right.' Schaffer nodded and immediately wished he hadn't. He gingerly fingered a bruise on the back, of his head. 'In the face. I must have struck my head as -- ' He broke off and turned slowly to face the door. 'What was that?'

'A dog. It sounded like a dog barking.'

'That's what I thought.' His voice slurred and indistinct, he staggered drunkenly across to the lower iron door and put his ear to it. 'Dogs,' he said. 'Lots of dogs. And lots and lots of hammering. Sledge-hammers, like enough.' He left the door and walked back to the centre of the floor, still staggering slightly. "They're on to us and they're coming for us. Where's the Major?'

'He went after them.' The voice was empty of all feeling. 'He jumped on to the top of the cable-car.'

'He did, eh?' Schaffer received the news as if Smith's action had been the most natural and inevitable thing in the world. 'How did he make out?'

'How did he make -- u' There was life back in her voice now, a shocked anger at Schaffer's apparent callousness. She checked herself and said: 'There was a fight and I think someone fell off the roof. I don't know who it was.'

'It was one of them,' Schaffer said positively.

'One of -- -how can you say that?'

"The Major Smiths of this world don't drive over the edge of a cliff. Quotation from the future Mrs. Schaffer. The Major Smiths of this world don't fall off the roofs of cable-cars. Quotation from the future Mrs. Schaffer's future husband.'

'You're recovering,' Mary said coldly. 'But I think you're right. There's still someone sitting on top of the cable-car and it wouldn't be one of them, would it?'

'How do you know there's someone sitting--'

'Because I can see him,' she said impatiently. 'It's bright moonlight. Look for yourself.'

Schaffer looked for himself, then rubbed a weary forearm across aching eyes. 'I have news for you, love/ he said. 'I can't even see the d.a.m.n' cable-car."

The cable-car was ten yards away from the central pylon. Smith, upright now, stooped, tore off the two friction fuses, straightened and, holding the cable in his left hand, took up position just on the inner side of the car roof. At the last moment he released his grip on the cable and stretched both arms out before him to break the impact of his body against the suspension arm. The ascending car on the other cable was now almost as close to the central pylon as his own. It didn't seem possible that he could make it in time.

The impact of the horizontal suspension arm drove the thought from his mind and all the breath from his body; had it not been for the buffering effect of his outstretched arms, Smith was sure, some of his ribs must have gone. As it was, he was almost completely winded but he forced himself to ignore the pain and his heaving lungs' demand for oxygen, swung his feet up till they rested on the lower cross-girder, hooked his hands round the upper girder and made his way quickly across to the other side. At least, his hands and his feet moved quickly, but the steel was so thickly coated in clear smooth ice that his scrabbling feet could find almost no purchase whatsoever on the lower girder. He had reached no farther than the middle when the ascending car began to pa.s.s under its suspension arm. For the first time that night Smith blessed the brightness of the moon. He took two more slipping, sliding steps and launched himself towards the ice-coated cable that glittered so brightly in the pale moonlight.

His left hand caught the cable, his right arm hooked over it and the cable itself caught him high up on the chest. He had made no mistake about the location of his hand and arm, but his sliding take-off had caused his body to fall short and the cable slid up under his chin with a jerk that threatened to decapitate him. His legs swung out far beneath him, swung back and touched the roof as he lowered himself to the full extent of his left arm. He released his grip on the cable, dropped on all fours and reached out blindly but successfully for one of the arms of the suspension bracket. For long seconds he knelt there, retching uncontrollably as he was flooded by the nausea and pain from his throat and still winded lungs: then, by and by, the worst of it pa.s.sed and he lay face down on the floor as the cable-car began to increase its pendulum swing with the increasing distance from the central pylon. He would not have believed that a man could be so totally exhausted and yet still have sufficient residual strength and sufficient self-preservation instinct to hang on to that treacherous and precarious hand-hold on that ice-coated roof.

Long seconds pa.s.sed and some little measure of strength began to return to his limbs and body. Wearily, he hauled himself up into a sitting position, twisted round and gazed back down the valley.

The cable-car he had so recently abandoned was now hardly more than fifty yards from the lowermost pylon. Thomas and Christiansen sat huddled in the middle, the latter wrapping a makeshift bandage round his injured hand. Both fore and aft doors were still open as they were when the abortive attack on Smith had been made. That neither of the two men had ventured near the extremities of the car to try to close either of the doors was proof enough of the respect, if not fear, in which Smith was now held.

From the roof of the cable-car came a brilliant flash of light, magnesium-blinding in its white intensity: simultaneously there came the sound of two sharp explosions, so close together as to be indistinguishable in time. The two rear supports of the suspension bracket broke and the car, suspended now by only the two front supports, tilted violently, the front going up, the rear down.

Inside, the angle of the floor of the car changed in an instant from the horizontal to at least thirty degrees. Christiansen was flung back towards the still open rear door. He grabbed despairingly at the side -- but he grabbed with his wounded hand. Soundlessly, he vanished through the open doorway and as soundlessly fell to the depths of the valley below.
