Twenty-five feet below him Schaffer peered cautiously over the edge of the header station roof. The guards and dogs were still patrolling the area round the roof of the volcanic plug. They had only to give one casual upwards glance and Smith's discovery was inevitable. Then some hair-prickling sixth sense made Schaffer look sharply upwards and he became very still indeed. The sentry, another circuit of the battlements completed, was standing with hands splayed out on the parapet, gazing out over the valley, perhaps watching the now dying flames from the burnt-out station: he had to lower his eyes only a fraction and that was that. Slowly, with his right hand, Schaffer brought up the Luger with the long perforated silencer screwed to its muzzle and laid it, in the best police fashion, across his left wrist. He had no doubt he could kill his man with one shot, the only question was when best to do it, how to weigh the balance of possibilities. If he waited until the man sighted them, he might give a warning shout or thrust himself back into cover before Schaffer could kill him. If he shot the sentry before he sighted them, then there would be no question of either escape or warning. But there was the possibility that the man might pitch forward over the battlements, crash off the roof of the header station and fall into the valley below, close by the patrolling men and dogs. A possibility only, Schaffer decided, not a probability: the slamming effect of the Luger shell would almost certainly knock him backwards off his feet. Schaffer had never before gunned down an unsuspecting man, but he coldly prepared to do so now. He lined up the luminous sight on the man's breast-bone and began to squeeze the trigger.
The moon went behind a cloud.
Slowly, stiffly, Schaffer lowered his gun. Schaffer, once again, wiped sweat from his forehead. He had the feeling that he wasn't through with brow-mopping for the night.
Smith reached the window, clambered over the sill, gave the rope two tugs as a signal for Schaffer to start climbing and passed into the room. It was almost totally dark inside, he'd just time to make out the iron bedstead which had been dragged to the window as anchorage for the rope when a pair of arms
'Easy on, easy on,' Smith protested. He was still breathing heavily and needed all the air he could get, but summoned enough energy to bend and kiss her. 'Unprofessional conduct, what's more. But I won't report it this time.'
She was still clinging to him, silent now, when Lieutenant Schaffer made his appearance, dragging himself wearily over the sill and collapsing on the iron bedstead. He was breathing very heavily indeed and had about him the air of one who has suffered much.
'Have they no elevators in this dump?' he demanded. It took him two breaths to get the words out.
'Out of training,' Smith said unsympathetically. He crossed to the door and switched on the light, hurriedly switched it off again. 'Damn. Get the rope in then pull the curtains.'
'This is the way they treated them in the Roman galleys,' Schaffer said bitterly. But he had the rope inside and the curtains closed in ten seconds. As Smith was manoeuvring the bed back into its original position, Schaffer was stuffing the nylon into their canvas bag, a bag, which, in addition to snowsuits and Schmeissers, contained some hand grenades and a stock of plastic explosives. He had just finished tying the neck of the bag when a key scraped in the lock.
Smith motioned Mary to stay where she was as he moved quickly to take up position behind the door: Schaffer, for all his alleged exhaustion, had dropped flat to the floor behind the bed with all the speed and silence of a cat. The door opened and a young Oberleutnant strode into the room, stopping short as he saw Mary, her hand to her mouth. His face registered astonishment, an astonishment almost immediately replaced by an anticipatory half-smile as he stepped forward beyond the opened door. Smith's arm came down and the young officer's eyes turned up in his head.
Smith studied the plans of the castle given him by Mary while Schaffer trussed up the Oberleutnant with the nylon, gagged him with tape and shoved him, jack-knifed, into the bottom of the cupboard. For good measure he pulled the top of the bed against the door.
'Ready when you are, boss."
'What's a minstrels' gallery?' Schaffer enquired.
'A gallery for minstrels. Then the next right-hander takes us to the east wing. Down again, second left. Telephone exchange.'
'Why there?' Schaffer asked. 'We've already cut the lines.'
"Not the ones between here and the barracks, we haven't. Want them to whistle up a regiment of Alpenkorps?' He turned to Mary. 'Helicopter still here?'
'It was when I arrived.'
'The helicopter?' Schaffer showed his puzzlement. 'What gives with the whirlybird, then?'
