The sharp, high-pitched call-up buzz of the telephone cut abruptly through the darkness on the cliff-top. Mallory stiffened and half-turned, hands clenching involuntarily. Again it buzzed, the jarring stridency carrying cleanly above the bass rumble of the thunder, fell silent again. And then it buzzed again and kept on buzzing, peremptory in its harsh insistence.

Mallory was half-way towards it when he checked in midstep, turned slowly round and walked back towards Andrea. The big Greek looked at him curiously.

«You have changed your mind?»

Mallory nodded but said nothing.

«They will keep on ringing until they get an answer,» Andrea murmured. «And when they get no answer, they will come. They will come quickly and soon.»

«I know, I know.» Mallory shrugged. «We have to take that chance — certainty rather. The question is-- how long will it be before any one turns up.» Instinctively he looked both ways along the windswept cliff-top: Miner and Brown were posted one on either side about fifty yards away, lost in the darkness. «It's not worth the risk. The more I think of it, the poorer I think my chances would be of getting away with it. In matters of routine the old Hun tends to be an inflexible sort of character. There's probably a set way of answering the phone, or the sentry has to identify himself by name, or there's a password — or maybe my voice would give me away. On the other han4 the sentry's gone without trace, all our gear is up and so's everyone except Stevens. In other words, we've practically made it. We've landed — and nobody knows we're here.»

«Yes.» Andrea nodded slowly. «Yes, you are right-- and Stevens should be up in two or three minutes. It would be foolish to throw away everything we've gained.» He paused, then went on quietly: «But they are going to come running.» The phone stopped ringing as suddenly as it had started. «They are going to come now.»,

«I know. I hope to hell Stevens …» Mallory broke off, spun on his heel, said over his shoulder, «Keep your eye open for him, will you? I'll warn the others we're expecting company.»

Mallory moved quickly along the cliff-top, keeping well away from the edge. He hobbled rather than walked — the sentry's boots were too small for him and chafed his toes cruelly. Deliberately he closed his mind to the thought of how his feet would be after a few hours' walking over rough territory in these boots: time enough for the reality, he thought grimly, without the added burden of anticipation… . He stopped abruptly as something hard and metallic pushed into the small of his bacL

«Surrender or die!» The drawling, nasal voice was positively cheerful: after what he had been through on the caique and the cliff face, just to set foot on solid ground again was heaven enough for DustyMiller.

«Very funny,» Mallory growled. «Very funny indeed.» He looked curiously at Miller. The American had removed his oilskin cape — the rain had ceased as abruptly as it had come — to reveal a jacket and braided waistcoat even more sodden and saturated than his trousers. It didn't make sense. But there was no time for questions.

«Did you hear the phone ringing just now?» he asked.

«Was that what it was? Yeah, I heard it».

«The sentry's phone. His hourly report, or whatever it was, must have been overdue. We didn't answer it. They'll be hot-footing along any minute now, suspicious as hell and looking for trouble. Maybe your side, maybe Brown's. Can't approach any other way unless they break their necks climbing over these boulders.» Mallory gestured at the shapeless jumble of rocks behind them. «So keep your eyes skinned.»

«I'll do that, boss. No shootin', huh?»

«No shooting. Just get back as quickly and quietly as you can and let us know. Come back in five minutes anyway.»

Mallory hurried away, retracing., his steps. Andrea was stretched full length on the cliff-top, peering over the edge. He twisted his head round as Mallory approached.

«I can hear him. He's just at the overhang.»

«Good.» Mallory moved on without breaking step. «Tell him to hurry, please.»

Ten yards farther on Mallory checked, peered into the gloom ahead. Somebody was coming along the clifftop at a dead run, stumbling and slipping on the loose gravelly soil.

«Brown?» Mallory called softly.

«Yes, sir. It's me.» Brown was up to him now, breathing heavily, pointing back in the direction he had just come. «Somebody's coming, and coming fast! Torches waving and jumping all over the place — must be running.»

«How many?» Mallory asked quickly.

«Four or five at least.» Brown was still gasping for breath. «Maybe more — four or five torches, anyway. You can see them for yourself.» Again he pointed backwards, then blinked in puzzlement. «That's bloody funny! They're all gone.» He turned back swiftly to Mallory. «But I can swear—»

«Don't worry,» Mallory said grimly. «You saw them all right. rye been expecting visitors. They're getting close now and taking no chances… . How far away?»

«Hundred yards — not more than a hundred and fifty.»

«Go and get Miller. Tell him to get back here fast.»

Mallory ran back along the cliff edge and knelt beside the huge length of Andrea.

«They're coming, Andrea,» he said quickly. «From the left. At least five, probably more. Two minutes at the most. Where's Stevens? Can you see him?»

«I can see him.» Andrea was magnificently unperturbed. «He is just past the overhang …» The rest of his words were lost, drowned in a sudden, violent thunderclap, but there was no need for more. Mallory could see Stevens now, climbing up the rope, strangely old and enfeebled in action, hand over hand in paralysing slowness, half-way now between the overhang and the foot of the chimney.

«Good God!» Mallory swore. «What's the matter with him? He's going to take all day …» He checked himself, cupped his hands to his mouth. «Stevens! Stevens!» But there was no sign that Stevens had heard. He still kept climbing with the same unnatural over-deliberation, a robot in slow motion.

«He is very near the end,» Andrea said quietly. «You see he does not even lift his head. When a climber does not lift his head, he is finished.» He stirred. «I will go down for him.»

«No.» Mallory's hand was on his shoulder. «Stay here. I can't risk you both… . Yes, what is it.» He was aware that Brown was back, bending over him, his breath coming in great heaving gasps.

«Hurry, sir; hurry, for God's sake!» A few brief words but he had to suck in two huge gulps of air to get them out. «They're on top of us!»

«Get back to the rocks with Miller,» Mallory said urgently. «Cover us… . Stevens! Stevens!» But again the wind swept up the face of the cliff, carried his words away.

«Stevens! For God's sake, man! Stevens!» His voice was low-pitched, desperate, but this time some quality in it must have reached through Stevens' fog of exhaustion and touched his consciousness, for he stopped climbing and lifted his head, hand cupped to his ear.

«Some Germans coming!» Mallory called through funnelled hands, as loudly as he dared. «Get to the foot of the chimney and stay there. Don't make a sound. Understand?»

Stevens lifted his hand, gestured in tired acknowledgment, lowered his head, started to climb up again. He was going even more slowly now, his movements fumbling and clumsy.

«Do you think he understands?» Andrea was troubled.

«I think so. I don't know.» Mallory stiffened and caught Andrea's arm. It was beginning to rain again, not heavily yet, and through the drizzle he'd caught sight of a hooded torch beam probing among the rocks thirty yards away to his left. «Over the edge with the rope,» he whispered. «The spike at the bottom of the chimney will hold it. Come on — let's get out of here!»

Gradually, meticulous in their care not to dislodge the smallest pebble, Mallory and Andrea inched back from the edge, squirmed round and headed back for the rocks, pulling themselves along on their elbows and knees. The few yards were interminable and without even a gun in his hand Mallory felt defenceless, completely exposed. An illogical feeling, he knew, for the first beam of light to fall on them meant the end not for them but for the man who held the torch. Mallory had complete faith in Brown and Miller… . That wasn't important. What mattered was the complete escape from detection. Twice during the last endless few feet a wandering beam reached out towards them, the second a bare arm's length away: both times they pressed their faces into the sodden earth, lest the pale blur of their faces betray them, and lay very still. And then, all at once it seemed, they were among the rocks and safe.
