He got up to go. He wanted to be alone⁠—alone, at least, with Bill. Mrs. Norbury had given him many things to think over, but the great outstanding fact which had emerged was this: that Cayley had reason to hate Mark⁠— Mrs. Norbury had given him that reason. To hate? Well, to be jealous, anyhow. But that was enough.

“You see,” he said to Bill, as they walked back, “we know that Cayley is perjuring himself and risking himself over this business, and that must be for one of two reasons. Either to save Mark or to endanger him. That is to say, he is either wholeheartedly for him or wholeheartedly against him. Well, now we know that he is against him, definitely against him.”

“But, I say, you know,” protested Bill, “one doesn’t necessarily try to ruin one’s rival in love.”

“Doesn’t one?” said Antony, turning to him with a smile.
