He plucked two lithe shoots of willow from a tree that grew by the water’s edge and stripped off the leaves.

“Come out,” he said, “and stand here with your back to me.”

Dennis looked at his father, and saw blind rage and fury in his face, as he peeled the willow wands.

“I’m awfully sorry, Father,” he said.

“You’ll be sorrier in a minute. Come here. I’m going to give you six of the smartest cuts you’ve ever had. It hurts more when you’re wet.”

Dennis stepped out of the water, and stood where his father pointed, and four strokes, savagely delivered, fell across his shoulders. He stood perfectly steady, gasping a little at the burning sting of them. As Colin slashed at him, he felt an exultant glee that at last he was hurting him to some purpose. He had spoiled the effect of his fortnight’s cruelty by that concession last night: this should start him afresh, with no apostasy to follow. He saw the red criss-cross of the strokes and the weals rising on the boy’s skin with some such ecstasy of satisfaction as he had seen Pamela standing in his room one night at Capri. And then in the middle of this chastisement he knew he could not strike Dennis again.

“That will do,” he said. “Turn round.”

Dennis turned and looked him straight in the eyes. In spite of the sharpness of the pain his face was in perfect control, his mouth was just a little compressed. And once more Colin knew that he had failed, for he saw there pain and bewilderment, mute reproach, but of fear not a trace nor yet of hate. With regard to himself he had failed also, for he had been literally unable to finish the punishment he had promised, and now he wanted to put his arm round Dennis’s neck, and kiss him, and tell him that he knew what a devil he was, and beg the boy’s forgiveness....

The very consciousness of that failure made him rage again.

“Well, did you like that?” he said. “It hurt, I expect.”
