 I believe, obtained a situation in the family of a surgeon resident in Essex. Indeed, it was I who recommended her to that gentleman. I have never heard from her since she left me."

"But you have communicated with her?" Robert asked, eagerly.

"No, indeed."

Mr. Audley was silent for a few moments, the shadow of gloomy thoughts gathering darkly on his face.

"May I ask if you sent a telegraphic dispatch to Miss Graham early in last September, stating that you were dangerously ill, and that you wished to see her?"

Mrs. Vincent smiled at her visitor's question.

But we must consult Tonks—Tonks is sure to be right."

Robert Audley wondered who or what Tonks could be; a diary, perhaps, or a memorandum-book—some obscure rival of Letsome.

Mrs. Vincent rung the bell, which was answered by the maid-servant who had admitted Robert.
