But there was the hut. And I thanked God for that. I wasn't thinking then about Farnell, or about Lovaas and his mate. I was thinking that I could light a fire and sink down in a chair and rest. God, I was tired — tired and cold and wretched! Nothing mattered. Nothing at all. In that moment I could have been offered the mines of Solomon, the treasure of the Incas, all the wealth of the Indies, and I wouldn't have cared a damn. What are the world's minerals worth when you're sick with exhaustion — weary right through to your bones and to the very marrow of your bones?

I started down to the hut. And then I stopped. Something had caught my eye — something that moved. I screwed up my eyes, trying to clear their vision which was half blinded by the whiteness of the snow. It was away to the right of the hut on the further shore of the largest of the frozen lakes. It was moving towards the valley that led up to the sombre mass of Sankt Paal. Was it reindeer? A bear, perhaps? But I think I knew what it might be even whilst I considered all the possible alternatives. I felt the excitement of the chase send the strength pumping back into my tired limbs. Lovaas — or was it Farnell? Had he given them the slip? No. The object had separated — there were two of them. It was Lovaas.

I searched farther on up the white slopes of the valley. And there, high up on the valley side another black speck moved steadily through the snow.

I didn't stop to think. I thrust my sticks hard into the snow and went hurtling down the slope to the flat ice of the lake. At least I could cut a corner here. Farnell — and Lovaas behind him — had gone down to the Gjeiteryggen hut. There they had to turn sharp right. By cutting across the lake I might save a mile, maybe two.

The chase was on now. Before, the quarry had been mythical, something that was there ahead, but only visible through the lines of the ski tracks. But now I could see them. They were real. No thought of what I should do if I came up with them crossed my mind. All my efforts were now bent on one thing — making the best possible speed and lessening the distance between myself and Lovaas.

I tumbled down a steep drift of snow and my skis scrunched as they bit the harder snow on the frozen lake. The ice held and I went forward easily across the flat surface. As I started to climb the long valley leading to Sankt Paal I wasn't more than a mile behind Lovaas and his mate. Every now and then, on a shoulder of the valley, I caught a glimpse of their two figures, black against the snow. I could even pick out Lovaas — he was so much shorter and stouter than the other. Once I caught sight of Farnell, a lone dot high up on the mountainside.

The tilt of the valley became steeper. Soon it was sheer willpower and nothing else that drove me forward. Every effort was concentrated on pushing forward. Twice I saw Lovaas turn and glance over his shoulder. He couldn't fail to see me. And yet I gave no thought to what I was going to do, how I was going to get past them to Farnell. It was enough that they were in sight. And I could spare no thought for anything other than the — task of holding the pace.

The tracks of the skis ahead were deep and clear now. There was no question of looking for the route. I had only to follow. But God how my legs ached! My breath came through my teeth in rasping gasps. Soon I was side-stepping up. I had not the energy to stride forward, my skis wide like crow's feet. Nor Could the others apparently. And it was some comfort to know that I was not the only one who was feeling exhausted.

Once, on a particularly steep stretch, I paused. The sweat was like ice on my forehead where the wind touched it. The sun had vanished now. The day had a bleak, wintry look. And away to my right the clouds were rolling in from the sea, covering the mountain tops. It was a bad outlook for crossing the glacier. If it were mist it might enable me to get past Lovaas to Farnell. But if it were snow… The thought sent a chill through me. A snowstorm at just on five thousand feet wasn't a good prospect. It would obliterate the ski tracks. It might even hide the posts marking the route.

I turned and pressed on. The fear of those clouds piling up from the west was what drove me forward now. I felt I had to get across the glacier before they reached me. But I hadn't a hope. In five minutes visibility was diminishing and the air was becoming much colder. I stopped and took a quick bearing on the direction that I knew the peak of Sankt Paal to be. Then I trudged on — climbing, climbing all the time. The clouds had no form now. They were a grey veil obliterating the valley behind me, swirling chill fingers round black outcrops of rock until nothing remained. Then my world became reduced to a small compass of snow that looked dirty and bleak in the half-light. The rest was a grey void. My only link with the world beyond that void was the sharp-cut lines of the ski tracks. They disappeared ahead in the curtain of mist, yet they always continued as I advanced.
