"But there's something I must tell you," she insisted, suddenly reminded.

"About what?"

"Last night--things that happened after everybody had gone to bed. You knew I was restless. I saw several things I haven't told you about. You ought to know. They may clear up the mystery of the theft."

"I already know all about that," Mrs. Gosnold declared calmly.

"About Mr. Lyttleton and the boat and the signals--"

Mrs. Gosnold turned sharply from her mirror. "What's this? Why didn't you tell me before?"

"I didn't know about the robbery, and I thought it was none of my affair--"

"It doesn't matter." Mrs. Gosnold caught up her cloak and threw it to the maid to adjust on her shoulders. "Whatever you saw had nothing to do with the robbery. Don Lyttleton's a bad lot in more ways than one, but he didn't steal my jewels last night--that I know."

"But who did?"

"I hope you may never find out."
