Schaffer twisted his head and peered downwards. It "was a dizzy, vertiginous and frankly terrifying spectacle. The entire valley below seemed to be swinging through a forty-five degree arc. One second he was looking at the line of pines that bordered the western slope of the valley, then the floor of the valley rushed by beneath them and seconds later he was staring at the line of pines that swept up the eastern side of the valley. He twisted his head upwards, but that was no improvement; the lights of the Schloss Adler careened wildly through the same dizzy arc: it was like being on a combination of a roller-coaster, big dipper and runaway Ferris wheel with the notable exception, Schaffer thought bleakly, that the coaster, dipper and Ferris wheel were provided with safety belts and other securing devices designed to prevent the occupant from parting company with his machine. The wind howled its high and lonely threnody through the cables and the suspension bracket. Schaffer looked away, screwed his eyes shut, lowered his head between his outstretched arms and moaned.
'Still think the horse the world's worst form of transport?' Smith asked. His lips were close to Schaffer's ear.
"Give me my boots and saddle,' Schaffer said, then, even more despairingly, 'Oh, no! Not again!'
Once more, without any warning, the moon had broken through, flooding the two men in its pale cold light. Gauging the time when the strain on their arms was least, they pulled the snow hoods far over their heads and tried to flatten themselves even more closely on to the roof.
In the Schloss Adler two people were watching the wild upward progress of the cable-car, now brilliantly illuminated by the moon. Through Mary's field-glasses two clearly distinguishable shapes of men could be seen stretched out on the cable-car roof. For half a minute she kept the glasses trained on them, then slowly turned away, her eyes wide, almost staring, her face empty of expression. Fifty feet above her head a sentry with slung gun patrolling the battlements stopped and gazed down at the cable-car crawling up the valley. But he didn't gaze for long. Although booted, gauntleted and muffled to the ears, he shook with the cold. It was no night for idle spectating. He looked away indifferently and resumed his brisk sentry-go.
He twisted his head upwards. The cold moon still sailed across a clear gap in the sky but was closing rapidly towards another bank of cloud. The castle battlements, with the header station at the base, seemed almost vertically above his head. So steeply was the car rising on this last section that the volcanic plug itself was now less than fourteen yards away. His gaze followed the volcanic plug downwards till it readied its base: down there, on the slopes below, patrolling guards and their Dobermann pinchers were barely the size of beetles.
'Suits her, doesn't it?' Schaffer said suddenly. Harsh edges of strain buried in his voice and his face was tight and desperate. 'A lovely name.'
'What are you talking about?' Smith demanded.
'Heidi.'
'Oh, my God!' Smith stared up at the rapidly closing header station. 'Her name is Ethel.'
'You didn't have to tell me.' Schaffer tried to sound aggrieved but it didn't quite come off. He followed Smith's upward gaze and, after a long pause, said very slowly: 'Jesus! Look at the slope of that goddamned roof!'
'I've been looking.' Smith eased his knife from its sheath and made a quick grab at the suspension bracket as a particularly violent swing almost broke his grip with his other hand. 'Get your knife ready. And for God's sake don't lose it.'
The moon slid behind a black patch of cloud and the valley was flooded with darkness. Slowly, carefully, as the cable-car approached the header station and the swaying motion dampened down, Smith and Schaffer eased their way to the after end of the car, rose gingerly but swiftly to their feet and
The front of the car passed under the lip of the header station roof. A moment later the suspension bracket followed and Smith lunged forward and upwards, flinging himself bodily on to the roof. His right arm struck downwards and the knife blade pierced the coating of ice and imbedded itself firmly in the wood beneath. Less than a second later Schaffer had landed beside him, the downward arcing knife making contact at exactly the same instant as himself.
The blade broke off at the hilt. Schaffer opened his hand, dropped the haft and clawed desperately at the ice. The dragging nails ripped through the encrusting ice, quite failing to hold him. He reached his left hand to his mouth, tore off the gauntlet and dug both hands in with all the strength that was in him. He slowed, but not enough. His scrabbling toes failed to find any more purchase and he knew he was sliding out over the edge -- and that when he went the first thing to halt his fall would be the rock-pile two hundred and fifty feet beneath at the base of the volcanic plug.
