“If it should be that I can ever help you—” she said, and paused.

“Thee has helped me,” he replied. “The world is a desert. Caravans from all quarters of the sun meet at the cross-roads. One gives the other food or drink or medicine, and they move on again. And all grows dim with time. And the camel-drivers are forgotten; but the cross-roads remain, and the food and the drink and the medicine and the cattle helped each caravan upon the way. Is it not enough?”

She placed her hand in his. It lay there for a moment. “God be with thee, friend,” he said.

The next instant Thomas Tilman Lacey’s drawling voice broke the silence.

“There’s something catching about these nights in Egypt. I suppose it’s the air. No wind—just the stars, and the ultramarine, and the nothing to do but lay me down and sleep. It doesn’t give you the jim-jumps like Mexico. It makes you forget the world, doesn’t it? You’d do things here that you wouldn’t do anywhere else.”

The gate was opened by the bowab, and the two passed through. David was standing by the brazier, his hand held unconsciously over the coals, his eyes turned towards them. The reddish flame from the fire lit up his face under the broad-brimmed hat. His head, slightly bowed, was thrust forward to the dusk. Hylda looked at him steadily for a moment. Their eyes met, though hers were in the shade. Again Lacey spoke. “Don’t be anxious. I’ll see her safe back. Good-bye. Give my love to the girls.”

David stood looking at the closed gate with eyes full of thought and wonder and trouble. He was not thinking of the girl. There was no sentimental reverie in his look. Already his mind was engaged in scrutiny of the circumstances in which he was set. He realised fully his situation. The idealism which had been born with him had met its reward in a labour herculean at the least, and the infinite drudgery of the practical issues came in a terrible pressure of conviction to his mind. The mind did not shrink from any thought of the dangers in which he would be placed, from any vision of the struggle he must have with intrigue, and treachery and vileness. In a dim, half-realised way he felt that honesty and truth would be invincible weapons with a people who did not know them. They would be embarrassed, if not baffled, by a formula of life and conduct which they could not understand.

It was not these matters that vexed him now, but the underlying forces of life set in motion by the blow which killed a fellow-man. This fact had driven him to an act of redemption unparalleled in its intensity and scope; but he could not tell—and this was the thought that shook his being—how far this act itself, inspiring him to a dangerous and immense work in life, would sap the best that was in him, since it must remain a secret crime, for which he could not openly atone. He asked himself as he stood by the brazier, the bowab apathetically rolling cigarettes at his feet, whether, in the flow of circumstance, the fact that he could not make open restitution, or take punishment for his unlawful act, would undermine the structure of his character. He was on the threshold of his career: action had not yet begun; he was standing like a swimmer on a high shore, looking into depths beneath which have never been plumbed by mortal man, wondering what currents, what rocks, lay beneath the surface of the blue. Would his strength, his knowledge, his skill, be equal to the enterprise? Would he emerge safe and successful, or be carried away by some strong undercurrent, be battered on unseen rocks?

He turned with a calm face to the door behind which sat the displaced favourite of the Prince, his mind at rest, the trouble gone out of his eyes.

“Uncle Benn! Uncle Benn!” he said to himself, with a warmth at his heart as he opened the door and stepped inside.
