"You know, then?"

"Positively." The lady adjusted her mask and caught her cloak about her. "Wait here till I come back. Then you may tell me about Don Lyttleton and the boat and the signals. I'll be as quick as I can."

She darted hurriedly away.

The wonder excited by Mrs. Gosnold's declaration that she knew the identity of the thief--even though, the girl told herself, she had all along suspected as much--kept Sally quiet for the next several minutes. She was sorely tempted to question the maid, but one look at that quiet, impassive countenance assured her that this would be wasted breath.

Insensibly the tempo of a haunting waltz that sang clear in the night beyond the open windows wove itself into the texture of Sally's thoughts and set her blood tingling in response.

She recalled Trego with a recurrent glow of gratification.

Poor fellow!

One foot began to tap the floor in time to the music. She hadn't danced once that night, had purposely avoided every chance of an invitation to dance. And now, of a sudden, she wanted to, without reason or excuse.

It was very curious. She wondered at herself. What had worked this change? Was it really nothing more nor less than a declaration of love on the part of a man she--didn't altogether like?

Though, of course, she hadn't ever been quite fair to him. He had admirable qualities. His honesty. His scorn of pretence and subterfuge. His simple faith in Sally Manvers, however misplaced.
