"Nothing, eh? nothing! That's the only answer in this case. To every question! To every search! Nothing, nothing, nothing;" and as he ended in a sinking voice, a startled cry rang out in the bedroom.

"Betty!" Ann exclaimed.

Hanaud threw off his dejection like an overcoat. Jim fancied that he was out of his chair and across the dressing-room before the sound of the cry had ceased. Certainly Betty could not have moved. She was standing in front of the dressing-table, looking down at a big jewel-case of dark blue morocco leather, and she was lifting up and down the open lid of it with an expression of utter incredulity.

"Aha!" said Hanaud. "It is unlocked. We have something, after all, Monsieur Frobisher. Here is a jewel-case unlocked, and jewel-cases do not unlock themselves. It was here?"

He looked towards the cupboard in the wall, of which the door stood open.

"Yes," said Betty. "I opened the door, and took the case out by the side handles. The lid came open when I touched it."

"Will you look through it, please, and see whether anything is missing?"

While Betty began to examine the contents of the jewel-case, Hanaud went to Francine, who stood apart. He took her by the arm and led her to the door.

"I am sorry if I frightened you, Francine," he said. "But, after all, we are not such alarming people, the Police, eh? No, so long as good little maids hold their good little tongues, we can be very good friends. Of course, if there is chatter, little Francine, and gossip, little Francine, and that good-looking baker's boy is to-morrow spreading over Dijon the story of Hanaud's little experiment, Hanaud will know where to look for the chatterers."

"Monsieur, I shall not say one word," cried Francine.
