Colin was now the more exhausted of the two, and after they had trotted some fifty yards together, Dennis staggering and hobbling in his skated boots, he had to stop.

“I can’t run any more,” he said. “Go on.”

He was terribly white of face, and his breath came in short panting sobs.

“That’s likely,” said Dennis. “Here, catch hold of me, Father. Give me your hand.

Colin’s spirit rebelled, but the flesh was weak, and he let Dennis tuck his arm in his, and pound away up the hill. The boy’s vigour and young blood had reasserted themselves, the colour came back to his cheeks, while the elder man, after his frantic struggle for them both, was growing every moment more exhausted. But presently they came to the level paving of the terrace, and Violet from within saw them pass a window, and rushed to the door to open it. Colin was now near collapse, but between them they lifted him into the warmth.

“Ring the bell, Dennis,” she said. “What has happened?”

“I was drowning,” said Dennis, “and he saved me.”

A few hours in bed encircled with hot water-bottles and blankets soon restored Dennis, but the cold had taken a much firmer grip over his father. For several days, without ever being dangerously ill, he was in danger of so being, for his vitality, which had always been so serene and vigorous, failed to recuperate him, and repel the effects of that icy struggle and its sequel of exhaustion. Never before in his life had he known a day’s sickness: now it seemed as if the spring of his vital force was drained. He made but little resistance; he let himself lie passively there while nurses and doctors fought for him. But all the time, as he lay there, and so slowly recovered his strength, a struggle more grim than that to which others could minister had laid hold on him. The exuberant vitality of his love of hate had suffered a shock to which that of his chilled and exhausted physical frame was not comparable. That vitality, never before seriously threatened, but always bubbling with energy, had collapsed at the moment when he vaulted over the sluice and crashed into the ice on his way to save Dennis. He, who loved life with every fibre of his being, and with every fibre of his being hated love, knew well enough that he risked his life and betrayed his vow of hate, when he did that. A moment before he had been smiling at this wonderful coincidence which would rid him of a survivor and supplanter, even as in identical manner, and at this same spot, he had been rid of that elder twin of his who stood between him and the lordship he coveted. And then came the humiliating collapse of his hate, before this assault of love.

And now as he lay here hour after hour of sunny wintry days and fitful sleep, it was not so much that he thought all this over, as that it was presented to him from outside, like a picture on the wall, which too was painted within his eyelids, so that when he closed them the images were still there. He saw himself, risking everything for Dennis’s sake, not because Dennis was his son, for that for many weeks now had been a solid ground of hatred, but because he loved the boy. With whatever incredulity he tried to counter that, it always slipped under his guard and stabbed him. He was forced to admit it to himself for the wound it made bled, but instinctively he covered it from others even as from Dennis himself, to whom, the moment after the danger was over, he had addressed those bitter and railing words, which came hot and fluent from the instinct of his soul. But still the flickering fire of hate, doused for that moment with deep and icy water, was alive, and day after day he refused to see the boy and Violet. And though, as his bodily strength returned, that fire burned more bravely, there was always present the knowledge that he had betrayed the Lord and Benefactor who all his life had done such great things for him. Was it in revenge for that betrayal that he had physically collapsed like this? Was it a warning that those whose souls were dedicated to evil had better not have commerce with love?

There was but a day left out of Dennis’s holidays when Colin came downstairs for the first time. He had debated with himself whether to keep himself withdrawn till the boy had gone, but this would deprive him of the opportunity of testifying that he still hated him. He must put himself right.... And all the time, for other reasons than these, he knew he wanted to see Dennis. Not even to himself would he admit that, but in some closed cell the knowledge lurked.
