After a few seconds I was convinced he didn't. In the first place, I couldn't see either Corazzini or Smallwood as men who would panic under pressure, no matter how severe that pressure, and in the second place suicidal risks weren't absolutely necessary, they would have stood a more than even chance of getting away with their lives and the -missile mechanism if they had stopped the tractor, got out and picked their cautious way down the glacier on foot, with their pistol barrels stuck in the backs of their hostages. Or would they—rather, did they think they would?
I tried fleetingly, frantically, to get inside their cold and criminal minds, to try to understand their conception of us. Did they think that we thought, like them, that the mechanism was all important, that human lives were cheap and readily expendable? If they did, and guessing the quality of Jackstraw's marksmanship with a rifle, would they not be convinced that they would be shot down as soon as they had stepped out on to the ice, regardless of the fate of their hostages? Or did they have a better understanding than that of minds more normal than their own?
Even as these thoughts flashed through my mind I knew I must act now. The time for thought, had there ever been such a time, was past. If they were left to continue in the tractor, they would either kill themselves on the glacier or if, by a miracle, they reached the bottom safely, they would then kill their hostages. If they were stopped now, there was a faint chance that Margaret and Levin might survive, at least for the moment: they were Smallwood's and Corazzini's only two trump cards, and would be kept intact as long as lay within their power, for they were their only guarantee of escape. I just had to gamble on the hope that they would be desperately reluctant to kill them where they were now, still a mile from the end of the glacier. And the last time I had gambled I had lost.
"Can you stop the tractor?" I asked Jackstraw, my voice a flat lifeless monotone in my own ear.
He nodded, his eyes on me: I nodded silently in return.
"You can't do that!" Zagero shouted in urgent protest. The drawl had gone for the first time ever. "They'll kill them, they'll kill them! My God, Mason, if you're really stuck on that kid you'd never—"
"Shut up!" I said savagely. I grabbed acoil of rope, picked up my rifle and went on brutally: "If you think they'd ever let your father come out of this alive you must be crazy."
A second later I was on my way, plunging out into the open across the narrow thirty-yard stretch of ice that led into the first of the fissures, wincing and ducking involuntarily as the first .303 shell from Jackstraw's rifle screamed past me, only feet to my right, and smashed through the hood of the Citroen and into the engine with all the metallic clamour, the vicious power of a sledge-hammer wielded by some giant hand. But still the Citroen came on.
I leapt across a narrow crevasse, steadied myself, glanced back for a moment, saw that Hillcrest, Joss, Zagero and a couple of Hillcrest's men were following, then rushed on again, weaving and twisting my way through the cracks and mounds in the ice. What was Zagero doing there, I asked myself angrily? Unarmed, with two useless hands that could hold no firearm, he was nothing but a liability, what could any man do with ruined hands like those? I was to find out just what a man with ruined hands could do. ...
We were running straight across the narrowest neck of the glacier making straight for the spot where the tractor would arrive if it survived Jackstraw's attempts to halt it: Jackstraw was firing in a line well above us now, but we could still hear the thin high whine of every bullet, the metallic crash as it struck the Citroen. Every bullet went home. But that engine was incredibly tough.
We were about half-way across when we heard the engine change gear, the high unmistakable whine of the tractor beginning to overrun its engine. Corazzini—I could clearly see him now, even without the aid of binoculars—must have found himself losing control on the steepening slope and was using the engine to brake the Citroen. And then, when we were less than a hundred yards away and after a longer than usual lull in the firing -Jackstraw must have stopped to change magazines—the sixth shell smashed through the riddled hood and the engine stopped as abruptly as if the ignition had been switched off.
The tractor stopped too. On that steep slope this was surprising, the last thing I would have expected, but there was no doubt that not only had it stopped but that it had been stopped deliberately: there was no mistaking the high-pitched screech of those worn brakes.
And then I could see the reason why. There was some violent activity taking place in the driving cabin of the tractor, and as we neared—a maddeningly slow process, there were dozens of crevasses to be jumped, as many more to be skirted—we could see what it was. Corazzini and Solly Levin were struggling furiously, and, from thirty or forty yards, it seemed, incredibly enough, that Solly Levin was getting the better of it. He had flung himself completely on top of Corazzini where the latter sat behind the wheel, and was butting him savagely in the face with the top of his bald head, and Corazzini, trapped in the narrow space, could find no room to make use of his much greater strength.
Then, abruptly, the door on the driver's side burst open—we could see it clearly, having been lower down than the tractor when it had stopped we were approaching it now almost head on—and the two men fell out fighting and struggling furiously. We could see now why Levin had been using his head—both hands were bound behind his back. It had been an act of desperate courage to attack Corazzini in the first place, but the old man wasn't to get the reward he deserved for his selflessness: even as we came up to them Corazzini got his automatic clear and fired down point-blank at Solly Levin who was lying helplessly on his back but still gamely trying to get a leg lock on the bigger man. I was a split second too late in getting there, even as I crashed into Corazzini and sent his automatic flying away to slide down the glacier, I knew I was too late, Solly Levin was a crumpled little blood-stained figure lying on the ice even before Corazzini's gun went slithering over the edge of a crevasse. And then I felt myself being pushed to one side, and Johnny Zagero was staring down at the outspread stillness of the man huddled at his feet. For what seemed an eternity, but was probably no more than three seconds, he stood there without moving, then when he turned to Corazzini his face was empty of all expression.
It might have been a flash of fear, of realisation that he had come to the end of his road that I saw in Corazzini's eyes, but I could never swear to it, the turn of his head, the sudden headlong dash for the shelter of the ice-covered moraine rocks by the side of the glacier, ten yards away, were so swift that I could be certain of nothing. But swift as he was, Zagero was even swifter: he caught Corazzini before he had covered four yards and they crashed to the glacier together, clawing, punching and kicking in the grim desperate silence of men who know that the winner's prize is his life.
"Drop that gun!" I whirled round at the sound of the voice behind me, but all I could see at first was the white strained face of Margaret Ross, the brown eyes dulled with sickness and fear. Involuntarily I brought up the rifle in my hands.
"Drop it!" Smallwood's voice was curt, deadly, his face barely visible behind Margaret's shoulder as he peered out through the canvas screen at the rear of the tractor cabin. He was completely shielded by her body—it was typical of the man's cunning, his ice-cold calculation that he should have waited until our attention was completely distracted before making his move. "And your friend. Quickly now!"
I hesitated, glanced at Hillcrest—the only other-man with a weapon—to see how he was placed, then jerked my head back again as there came a sudden plop from the silenced automatic and a sharp cry of pain from Margaret. She was clutching her left arm just below the elbow.
