"And how wise that will be, little Francine!" Hanaud rejoined in a horribly smooth and silky voice. "For Hanaud can be the wickedest of wicked Uncles to naughty little chatterers. Ohhoho, yes! He seizes them tight—so—and it will be ever so long before he says to them 'That—will—do—now!'"

He rounded off his threats with a quite friendly laugh and gently pushed Francine Rollard from the room. Then he returned to Betty, who had lifted the tray out of the box and was opening some smaller cases which had been lying at the bottom. The light danced upon pendant and bracelet, buckle and ring, but Betty still searched.

"You miss something, Mademoiselle?"

"Yes."

"It was, after all, certain that you would," Hanaud continued. "If murders are committed, there will be some reason. I will even venture to guess that the jewel which you miss is of great value."

"It is," Betty admitted. "But I expect it has only been mislaid. No doubt we shall find it somewhere, tucked away in a drawer." She spoke with very great eagerness, and a note of supplication that the matter should rest there. "In any case, what has disappeared is mine, isn't it? And I am not going to imitate Monsieur Boris. I make no complaint."

Hanaud shook his head.

"You are very kind, Mademoiselle. But we cannot, alas! say here 'That will do now.'" It was strange to Jim to notice how he kept harping upon the words of that whisper. "We are not dealing with a case of theft, but with a case of murder. We must go on. What is it that you miss?"

"A pearl necklace," Betty answered reluctantly.

"A big one?"
