"Of course not. You could come along if you liked. That's one way of settling the business out of hand. A day or two after, Rashburn would ask me how the story was going on, and I should say that I had showed you a flaw in it, and that as the money had been forthcoming the affair was finished on much too matter-of-fact lines to give an interesting finish. He would understand."

"And his diplomacy would be unspotted," Harold smiled. "But I fancy we are not going to be allowed to finish quite in this light-hearted way. We have Frobisher to deal with—Frobisher who suggested that Mrs. Benstein should appear in the role of the Queen of the Rubies. He knew that Benstein had the Blue Stone; he knew that Mrs. Benstein is in the habit of borrowing gems left with her husband for security; and he calculated on her borrowing that pearl amongst rubies for to-night. Do you suppose, knowing Frobisher's character, that he means that stone to leave the house?"

"I know that he is an utterly unscrupulous scoundrel," Parkford said freely. "Oh, he is quite capable of this kind of thing. Do you happen to know anything of Miss Lyne?"

"I am engaged to be married to her," Harold said quietly.

The little brown-faced man whistled softly, but his features expressed no astonishment.

"I thought your English was uncommonly good for a native," he said. "Of course, I know all about you now. My wife, who knows the history of everybody in London, I believe, told me about Harold Denvers and Miss Lyne, and how you had been forbidden the house and all that kind of thing. I seem to remember, too, that at one time your father and Frobisher were by the way of being friends."

"To my father's cost," Harold said with some little bitterness. "He robbed and ruined my father, and he died a broken man. That was before Frobisher put money in his purse by so shamefully abusing his position in the diplomatic service. As to Miss Lyne——"

"Miss Lyne may be of the greatest possible service to us," Parkford said.

"She is of use at the present moment," Harold said. "Of course she knows I am here and why, though I should be kicked out of the house if discovered. Miss Lyne is keeping Mrs. Benstein out of the way for the moment—out of Frobisher's way, that is."

Parkford jerked his thumb over his right shoulder and nodded. As Harold looked up he saw the shifting figure of Frobisher passing through the crowd. His eyes were narrow and eager, he seemed to be looking furtively and greedily for some one.
