“Good-by, Fa,” Robin had whispered back, with his eyes on the tower.

With a very careful movement he had lifted his face to be kissed, and on his soft lips Dion had felt a certain remoteness. Did the tower stand between him and his little son as he said good-by to Robin?

Just as he had reluctantly let Robin go and, with his legs crossed, had been about to perform the feat of getting up without touching the floor with his hands, and without shaking the bricks in their places,—moved to this trifling bodily feat by the desire to confront his emotion with an adversary,—the door behind him had been opened. Already in movement he had instinctively half-turned round. Something had happened,—he never knew exactly what,—something had escaped from his physical control because his mind had abruptly been deflected from its task of vigilance; there had been a crash and a cry of “Oh, Fa!” from Robin, and he had met Rosamund’s eyes as the tower toppled down in ruin. Not so much as one brick had been left upon another.

Robin had been greatly distressed. Tears had come into his eyes, and for a moment he had looked reproachfully at his father. Then, almost immediately, something chivalrous had spoken within him, admonishing him, and he had managed a smile.

“It’ll be higher next time, Fa, won’t it?” he had murmured, still evidently fighting a keen disappointment.

And Dion had caught him up, given him a hug, whispered “My boy!” to him, put him down and gone straight out of the room with Rosamund, who had not spoken a word.

And that had been the last of Robin for his father.

In the evening, when Robin was asleep, Dion had said good-by to Rosamund. The catastrophe of the tower of bricks had haunted his mind. As he had chosen to make of the tower an omen, in its destruction he had found a presage of evil which depressed him, which even woke in him ugly fears of the future. He had had a great deal out of life, not all he had wanted, but still a great deal. Perhaps he was not going to have much more. He had not spoken of his fears to Rosamund, but had been resolutely cheerful with her in their last conversation. Neither of them had mentioned the possibility of his not coming back. They had talked of what probably lay before him in South Africa, and of Robin, and presently Rosamund had said:

“I want to make a suggestion. Will you promise to tell me if you dislike it?”

“Yes. What is it?”
