Smith came up the last few feet of the sloping roof at the end of the rope, caught Schaffer's hand, stood upright on the flat inner section of the roof and at once began to unwind the rest of the knotted rope from his waist. Schaffer, although the temperature was far below freezing, wiped his brow like a man in a heat-wave.
“Brother!” He mopped his brow some more. “If I can ever do you a favour, like lending you a car-fare—”
Smith grinned, clapped his shoulder, reached up into the gloom, caught the weighted end of the suspended string and quickly bent the nylon on to it. He gave two gentle tugs and the rope began to move upwards as Mary hauled it in through the window. Smith waited until two more gentle return tugs indicated that the rope was securely fastened and began to climb.
He was half-way up to the window when the moon broke through. In his Alpenkorps uniform he was perfectly silhouetted against the gleaming white of the castle walls. He hung there motionless, not daring to move, not so much as even daring to glance upwards or downwards lest the movement attract some hostile attention.
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 wound tightly round his neck and someone started murmuring incoherently in his ear.
“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.
