"That is a very pretty and ingenious hiding-place," Mrs. Benstein said at length. "No enemy would think of looking for it there. Your Highness has many enemies?" "Ask Hamid Khan yonder," the Shan said crisply. "He can tell you." The wretched Hamid wriggled and bowed. It was evident that he had been taken quite by surprise. The Shan sealed the documents and carelessly tossed them across the table. The Blue Stone glittered there well within the reach of Frobisher, and his fingers itched for it. "Put the jewel away," he said hoarsely. "It is dangerous to leave it there." "A fresh hiding-place," the Shan laughed. "I feel quite nervous. Suppose that I get Parkford to take care of it for me until I get home. He is a man to be trusted, and not a man lightly to molest. Sir, will you do me the favour?" Parkford coolly dropped the gem into his waistcoat pocket. At the same time he passed a folded strip of paper to Mrs. Benstein and nodded significantly. Then he rose. "I am desolated," he said, "but really I have to leave. Denvers, a word with you." The luncheon-party broke up upon this, Mrs. Benstein alone remaining. She had arranged to wait here for a friend, she explained. Frobisher slid away, followed by Hamid Khan, and outside Denvers put Angela into a passing taxi. He had work before him this afternoon. "That was very neatly done," Parkford said to the Shan. "It was a pleasure to see Frobisher’s face. You saw me pass my cheque over to Mrs. Benstein, who will hand it to her husband. If you take my advice you will allow me to deposit the Blue Stone with my bankers for the present. I am going that way, and I shall see that it is all safe." "Put it where you like," the Shan said, recklessly. "It’s all the same to me, knowing as I do that I have an honest man to deal with. This rigid virtue of mine is undermining my constitution. I’ll go off to the club, and try and get a game of bridge. Dine with me to-night, Denvers?" Denvers excused himself on the plea of urgent business; besides, it was strongly probable that His Highness of Koordstan would be beyond entertaining by dinner-time. "You’ve got our dusky friend out of a tight place," Harold suggested. "So I suppose," Parkford said, indifferently. "I like this kind of intrigue, and I have a fancy for acting unofficially for the Government. Sometimes the hobby proves expensive, sometimes the information is valuable. In this case I am going to make a good thing out of it. I am very glad, for your sake, that you told Lord Rashburn all about it. It’s given me a grip upon the Shan, and I’ll see that you get your concessions. But we must discuss that another time." Harold went on his way with hope rising high within him. He began to see his way clear now, once the mystery of the Cardinal Moth was fathomed. Lefroy passed him presently, and turned into the Belgrave. Harold wondered if this was the friend whom Mrs. Benstein was expecting.
