"Give it up," she begged. "Don't bet any more."

"Give up betting when I've just won twenty-five thousand pounds over the Guineas and am going to win one hundred and twenty-five thousand pounds over the Derby? Besides, I thought you were going to live happily ever afterward if Moonbeam won?"

He turned away again with a laugh, and Tufton's grave head-shake was not much consolation to Dorothy. She was walking away a few paces in order not to overhear Tony's jovial badinage with the bookmakers, when a suave voice addressed her over the shoulder and, looking round, she saw Leopold Hausberg.

"You've forgotten me, Lady Clarehaven," he was saying. "I must explain that I—"

"Yes, yes," Dorothy interrupted, quickly, "you're Mr. Houston. I've just been told so by Mr. Lonsdale, whom no doubt you also remember."

She mentioned Lonsdale's name deliberately to see if Houston would speak about the monkey or even show a hint of displeasure at the mention of Lonsdale's name, but there was no shadow on his countenance, and he only asked her if she would not introduce him to her husband.

"I should like to congratulate him," he said, "though his win hit me pretty hard."

At this moment Tony with a laugh closed his betting-book and joined them.

"By Jove! there's not a sportsman among you," he called back to the bookmakers. "What do you think, Doodles? There's not one of them who'll give me four thousand to a thousand against Moonbeam for the Derby.... I'm sorry, I didn't see you were talking to somebody."

Dorothy made the introduction.
