Some said hee brake ribs one or two,

the island. Without compass, stars or moon to guide, Mallory had nothing to orientate them but the feel of the slope of the mountain and the map Viachos had given them in Alexandria. But by and by he was reasonably certain that they had rounded the mountain and were pushing up some narrow gorge into the interior. The snow was the deadly enemy. Heavy, wet and feathery, it swirled all around them in a blanketing curtain of grey, sifted down their necks and jackboots, worked its insidious way under their clothes and up their sleeves, blocked their eyes and ears and mouths, pierced and then anaesthetised exposed faces, and turned gloveless hands into leaden lumps of ice, benumbed and all but powerless. All suffered, and suffered badly, but Stevens most of all. He had lost consciousness again within minutes of leaving the cave and clad in clinging, sodden clothes as he was, he now lacked even the saving warmth generated by physical activity. Twice Andrea had stopped and felt for the beating of the heart, for he thought that the boy had died: but he could feel nothing for there was no feeling left in his bands, and could only wonder and stumble on again. About five in the morning, as they were climbing up the steep valley head above the gorge, a treacherous, slippery slope with only a few stunted carob trees for anchor in the sliding scree, Mallory decided that they must rope up for safety's sake. In single file they scrambled and struggled up the ever-steepening slope for the next twenty minutes: Mallory, in the lead, did not even dare to think how Andrea was getting on behind him. Suddenly the slope eased, flattened out completely, and almost before they realised what was happening they bad crossed the high divide, still roped together and in driving, blinding snow with zero visibility, and were sliding down the valley on the other side. They came to the cave at dawn, just as the first grey stirrings of a bleak and cheerless day struggled palely through the lowering, snow-filled sky to the east. Monsieur Vlachos had told them that the south of Navarone was honeycombed with caves, but this was the first they had seen, and even then it was no cave but a dark, narrow tunnel in a great heap of piled volcanic slabs, huge, twisted layers of rock precariously poised in a gulley that threaded down the slope towards some broad and unknown valley a thousand, two thousand feet beneath them, a valley still shrouded in the gloom of night. It was no cave, but it was enough. For frozen, exhausted, sleep-haunted men, it was more than enough, it was plug digital camera into mp3 player more than they had ever hoped for. There was room for them all, the few cracks were quickly blocked against the drifting snow, the entrance curtained off by the boulder-weighted tent. Somehow, impossibly almost in the cramped darkness, they stripped Stevens of his sea- and rain-soaked clothes, eased him into a providentially zipped sleeping-bag, forced some brandy down his throat and cushioned the blood-stained head on some dry clothing. And then the four men, even the tireless Andrea, slumped down to the sodden, snow-chilled floor of the cave and slept like men already dead, oblivious alike of the rocks on the floor, the cold, their hunger and their clammy, saturated clothing, oblivious even of the agony of returning circulation in their frozen hands and faces. CHAPTER 7 Tuesday 15001900 The sun, rime-ringed and palely luminous behind the drifting cloud-wrack, was far beyond its zenith and dipping swiftly westwards to the snow-limned shoulder of the mountain when Andrea lifted the edge of the tent, pushed it gently aside and peered out warily down the smooth sweep of the mountain side. For a few moments he remained almost motionless behind the canvas, automatically easing cramped and aching leg muscles, narrowed, roving eyes gradually accustoming themselves to the white glare of the glistening, crystalline snow. And then he had flitted noiselessly out of the mouth of the tunnel and reached far up the bank of the gully in half a dozen steps; stretched full length against the snow, he eased himself smoothly up the slope, lifted a cautious eye over the top. Far below him stretched the great, cpxved sweep of an almost perfectly symmetrical valleya valley born abruptly in the cradling embrace of steep-walled mountains and falling away gently to the north. That towering, buttressed giant on his right that brooded darkly over the head of the valley, its peak hidden in the snow cloudsthere could be no doubt about that, Andrea thought, Mt. Kostos, the highest mountain in Navarone: they had crossed its western flank during the darkness of the night. Due east and facing his own at perhaps five miles' distance, the third mountain was barely less high: but its northern, flank fell away more quickly, debouchbig on to the plains that lay in the northeast of Navarone. And about four miles away to the
