Dora, really alarmed, rushing to her dressing-case, seizes upon a flask of eau-de-Cologne, and flings some of its contents freely over the fainting girl. Florence, with a sigh, rouses herself, and sits upright.

"There is no time to lose," she says confusedly. "Oh, Dora!" Here she breaks down and bursts into tears.

"Try to compose yourself," entreats Dora, seeing the girl has some important news to impart, but is so nervous and unstrung as to be almost incapable of speaking with any coherence. But presently Florence grows calmer, and then, her voice becoming clear and full, she is able to unburden her heart.

"All this day I have been oppressed by a curious restlessness," she says to Dora; "and, when you left me this afternoon, your vague promises of being able to elucidate the terrible secret that is weighing us down made me even more unsettled. I did not go down to dinner--"

"Neither did I," puts in Mrs. Talbot sympathetically.

"I wandered up and down my room for at least two hours, thinking always, and waiting for the moment when you would return, according to promise, and tell me the success of your hidden enterprise. You did not come, and at half past nine, unable to stay any longer in my own room with only my own thoughts for company, I opened my door, and, listening intently, found by the deep silence that reigned throughout the house that almost every one was gone, if not to bed, at least to their own rooms."
