"GFX calling GFK. GFX calling GFK. We are receiving you faint but clear. Repeat, we are receiving you. Over."
I fumbled and nearly dropped the mike in my excitement.
"GFK calling GFX, GFK calling GFX." I almost shouted the words, saw Jackstraw pointing to the switch which was still in the receiving position, cursed my stupidity, threw it over, called out the signs again and then, quite forgetting the procedure and etiquette of radio communication, rushed on, the words tumbling over one another: "Dr Mason here. Dr Mason here. Receiving you loud and clear. Is that you, Joss?" I threw the switch.
"Yes, sir. Glad to hear from you." Static lent a flat impersonality to the crackling words, robbed them of meaning. "How are you? What weather, how far out?"
"Going strong," I replied. "Cold intense - minus 70°. Approximately 120 miles out. Joss, this is a miracle! How on earth did you fix it?"
"I didn't," he said unemotionally. There was a pause and then his voice came again. "Captain Hillcrest is waiting to speak to you, sir."
"Captain Hillcrest! What on earth is Captain Hillcrest-" I broke off abruptly, not through astonishment, great though that was, that Hillcrest, whom I had believed to be almost 250 miles to the north of our IGY cabin should have suddenly turned up there, but because the warning glance from Jackstraw had found an echoing answer in the back of my own mind. "Hold on," I said quickly. "Will call you back in two or three minutes."
We had set up the transmitter just to the rear of the tractor cabin, and I knew that every word said on both sides could be heard by those inside. It was just then that the curtains parted and Corazzini and Zagero peered out, but I ignored them. I never cared less about the hurt I was offering to anybody's feelings, just picked up the radio and generator while Jackstraw unstrung the antenna, and walked away from the tractor. Two hundred yards away I stopped. Those in the tractor could still see us - the brief light of noonday was flooding over the ice-cap - but they could no longer hear us.
We rigged the radio again, and I tried to tap out the call-sign but it was hopeless, we'd been out too long in that dreadful cold and my hand was beating an uncontrollable tattoo on the key. Fortunately, they knew or guessed at the other end what was happening, for Hillcrest's voice, calm, confident, infinitely reassuring, came through as soon as I pressed the receiving switch.
"Surprise, surprise," the mike crackled mechanically. "OK, Dr Mason, from what Joss has said - and the recent delay -1 guess you're a good way from the tractor. At seventy below you won't want to stay there too long. Suggest I do all the talking. I'll keep it brief. Receiving me?"
"Loud and clear. What on earth are you - sorry, carry on."
"Thanks. We heard Monday afternoon, on both British and American broadcasts, of the overdue airliner. Tuesday morning -yesterday, that is - we heard from the Uplavnik base. They say this hasn't been announced officially, but the US and British governments are convinced that the plane has not been lost at sea, but that it has landed somewhere in Greenland or Baffin Island. Don't ask me why they're convinced - I've no idea. Anyway, they've mounted the biggest air-sea rescue search since the war. Merchant vessels of several nationalities have been diverted. American, British, French and Canadian fishing trawlers are moving in to the Greenland coast - the west coast mainly. The east's already blocked with ice. A dozen US air force search bombers are already operating from Thule and Sondre Strom-fjord. US coastguard cutters are on the job, a flotilla of Canadian destroyers have been rerouted from mid-Atlantic and are steaming at full speed for the southern entrance of the Davis Strait - although it will take them at least thirty-six more hours to get there - and a British aircraft-carrier, accompanied by a couple of destroyers, has already rounded Cape Farewell: we don't know yet how far north she can get, the ice is solid on the Baffin side, but it's open at least to Disko on the Greenland coast, maybe as far as Svartenhuk. All IGY stations in Greenland have been ordered to join in the search. That's why we came back non-stop to the cabin - to pick up more petrol."
I could contain myself no longer, threw over the receiving switch.
"What on earth's all the mad flap about? You'd think the President of the United States and half the Royal Family were aboard that plane. Why no more information from Uplavnik?"
I waited, and then Hillcrest's voice crackled again.
"Radio transmission impossible during preceding twenty-four hours. Will raise them now, tell them we've found the missing plane and that you're on your way to the coast. Any fresh developments with you?"
"None. Correction. One of the passengers - Mahler - turns out to be an advanced diabetic. He's in a bad way. Radio Uplavnik to get insulin. Godthaab will have it."
"Wilco," the microphone crackled back. A long pause, during which I could faintly hear the murmur of conversation, then Hillcrest came on again. "Suggest you return to meet us. We have plenty of petrol, plenty of food. With eight of us on guard instead of two, nothing could happen. We're already forty miles out" -1 glanced at Jackstraw, caught the sudden wrinkling of the eyes which I knew to be the tell-tale sign of a quick grin of astonished delight which so accurately reflected my own feelings - 'so not more than eighty miles behind you. We could meet up in five or six hours."
I felt elation wash through me like a releasing wave. This was wonderful, this was more than anything I had ever dared hope for. All our troubles were at an end. . . . And then the momentary emotion of relief and triumph ebbed, the cold dismaying processes of reason moved in inexorably to take their place, and it didn't require the slow, definite shake of Jackstraw's head to tell me that the end of our troubles was as far away as ever.
"No go," I radioed back. "Quite fatal. The minute we turned back the killers would be bound to show their hand. And even if we don't turn they know now that we've been in contact with you and will be more desperate than ever. We must go on. Please follow at your best speed." I paused for a moment, then continued. "Emphasise to Uplavnik essential for our lives to know why crashed plane so important. Tell them to find out the passenger list, how genuine it is. This is absolutely imperative, Captain Hillcrest. Refuse to accept 'No' for an answer. We must know."
We talked for another minute, but we'd really said all there was to be said. Besides, even during the brief periods that I'd pushed down my snow-mask to speak the cold had struck so cruelly at my cut and bleeding lips that I could now raise scarcely more than a mumble, so after arranging an 8 p.m. rendezvous and making a time-check I signed off.
Back in the tractor cabin curiosity had reached fever pitch, but at least three minutes elapsed - three excruciatingly uncomfortable minutes while Jackstraw and I waited for the blood to come surging back through our frozen veins - before anyone ventured to speak. The inevitable question came from the Senator - a now very much chastened Senator who had lost much of his choler and all of his colour, with the heavy jowls, hanging more loosely than ever, showing unhealthily pale through the grey grizzle of beard. The very fact that he spoke showed, I suppose, that he didn't regard himself as being heavily under suspicion. He was right enough in that.
"Made contact with your friends, Dr Mason, eh? The field party, I mean." His voice was hesitant, unsure.
"Yes," I nodded. "Joss - Mr London - got the set working after almost thirty hours' non-stop work. He raised Captain Hillcrest -he's in charge of the field party - and managed to establish a relay contact between us." I'd never heard of the phrase 'relay contact' in my life, but it sounded scientific enough. "He's packing up immediately, and coming after us."
"Is that good?" the Senator asked hopefully. "I mean, how long-?"
"Only a gesture, I'm afraid," I interrupted. "He's at least 258 miles away. His tractor's not a great deal faster than ours." It was, in fact, almost three times as fast. "Five or six days, at the least."
Brewster nodded heavily and said no more. He looked disappointed, but he looked as if he believed me. I wondered which of them didn't believe me, which of them knew I was lying because they knew that they had so thoroughly destroyed all the spare condensers and valves that it would have been quite impossible for Joss to repair the RCA.
The long bitter day, a day filled by nothing except that dreadful cold, an endless suffering and the nerve-destroying thunderous roar and vibration of that big engine, crawled by like a dying man. About two-thirty in the afternoon, as the last glow of the noon-light faded and the stars began to stand clear in the cold and brittle sky, the temperature reached its nadir - a frightening 73 degrees below zero. Then it was, that strange things happened: flashlights brought from under a parka died out inside a minute: rubber became hard as wood and cracked and fractured like wood: breath was an opaque white cloud that shrouded the heads of every person who ventured outside the tractor body: the ice-cap froze to such an unprecedented degree of hardness that the tractor treads spun and slipped on flat surfaces, the crimp marks no more than half-seen hairlines on the ground: the dogs, who could with impunity stand up to howling blizzards that would kill any man, whined and wailed in their utter misery in that appalling cold: and, now and again, like some far-off intimation of doom and the end of the world, a dull rumbling sound would come echoing across the ice-cap and the ground shake beneath the treads of the tractor as some great areas of snow and ice contracted still farther under the iron hand of that glacial cold.
It was then, inevitably, that the tractor started to give trouble: it was only a matter for wonder that it hadn't broken down long before that. What I feared above all was the shearing of some moving metal part, made brittle by that intense cold, that would have been the end of us: a valve-stem, a cam-rod, any one part of the delicate timing mechanism, even so small a thing as a crankshaft pin: it needed just one of these to go, and we would be gone also.
We were spared these lethal mishaps, but what we had was almost as bad. Carburettor ice was a constant problem. The steering box froze up and had to be thawed out by blow-torches. Generator brushes stuck and broke, but fortunately we carried spares enough of these. But the biggest trouble was the radiator. Despite the fact that we had it heavily lagged, the cold penetrated the lagging as if it were tissue paper and the subsequent metal contraction produced distortion. Soon it began to leak, and by three o'clock in the afternoon we were losing water at dismaying speed. I doled out some of our precious reserves of heat pads for Mahler's feet, with the instructions that the water from the snow-buckets on the stove was to be kept solely for the radiator. But even with blow-torches assisting the heat of a stove, the melting of super-chilled snow is a discouragingly slow process: soon we were reduced to pouring half-melted slush down the radiator cap, and finally to cramming snow itself down in order to keep going at all. All this was bad enough: but the frightening thing was that for every pint of radiator liquid lost and every pint of snow-water used to replace it, the anti-freeze became that much more diluted, and though we carried a small reserve drum of ethylene glycol its weight diminished perceptibly with every halt we made.
We had, hours before that, dispensed with a lookout, and the burden of all this work fell on Jackstraw, Zagero, Corazzini and myself. Of the four of us, Jackstraw was the only one who escaped what I knew would be permanent injury or disfigurement in the shape of scars and destroyed tissue. Zagero might never before have borne any of the scars of his trade, but he was going to have what looked peculiarly like one now: we had been too late in getting a cold-water compress to his right ear, and these destroyed tissues would need plastic surgery: two of Corazzini's toes had also been left too long without treatment, and I knew that he, too, would finish up in a surgical ward: and, because I was the one most in contact with the engine, my fingertips were a painful bleeding mess, the nails already blackening and beginning to rot away.
Nor were things a great deal better with those inside the tractor cabin. The first physiological effects of the cold were beginning to assert themselves, and assert themselves strongly - the almost overpowering desire for sleep, the uncaring indifference to all that went on around them. Later would come the sleeplessness, the anaemia, the digestive troubles, the nervousness that could lead to insanity - if the cold continued long enough these conditions would inevitably succeed the picture of huddled, lifeless misery that presented itself to me whenever I sought the shelter of the cabin and the agony of returning circulation after my spell at the wheel. Many times I saw the picture that afternoon, and always the picture was the same.
The Senator sat slumped in a corner, a dead man but for the fits of violent shuddering that overtook him at regularly recurring intervals. Mahler appeared to sleep. Mrs Dansby-Gregg and Helene lay huddled in one another's arms - an incredible sight, I thought, but then, next only to death itself, the Arctic was the great leveller, an unparalleled agent in stripping away the pretensions and shoddy veneers of everyday living. I was no great believer in the sudden conversions of human nature, and was pretty certain that, with Mrs Dansby-Gregg, the return to civilisation would coincide with the return to her normal self, and that this moment of common humanity shared by herself and her maid would be no more than a fading and unwelcome memory: but for all my dislike of Mrs Dansby-Gregg, I was beginning to develop more than a sneaking admiration for her. The carefully cherished snobbery, the maddeningly easy and condescending assumption of an inevitable social superiority were irritating enough, heaven knew, but behind that unlovable facade seemed to lie a deep-buried streak of that selflessness which is the hallmark of the genuine aristocrat: although she complained constantly about the tiny irritations, she was silent on matters that caused her genuine suffering: she was developing a certain brusque helpfulness, as if she was half-ashamed of it, and showed a care for her maid which, though probably no more than that feudal kindness that reaches its best in adversity, nevertheless verged almost on tenderness: and I had seen her take a mirror from her handbag, inspect the ravages frostbite had wreaked on her lovely face, then return the mirror to her bag with a gesture of indifference. Mrs Dansby-Gregg, in short, was becoming for me an object lesson against the dangers of an over-ready classification of people into types.
