Dr. Mosgrave looked at his watch, a fifty-guinea Benson-made chronometer, which he carried loose in his waistcoat pocket as carelessly as if it had been a potato.

"I need not remind you that my time is precious," he said; "your telegram informed me that my services were required in a case of—danger—as I apprehend, or I should not be here this morning."

Robert Audley had sat looking gloomily at the fire, wondering how he should begin the conversation, and had needed this reminder of the physician's presence.

"You are very good, Dr. Mosgrave," he said, rousing himself by an effort, "and I thank you very much for having responded to my summons. I am about to appeal to you upon a subject which is more painful to me than words can describe. I am about to implore your advice in a most difficult case, and I trust almost blindly to your experience to rescue me, and others who are very dear to me, from a cruel and complicated position."

The business-like attention in Dr. Mosgrave's face grew into a look of interest as he listened to Robert Audley.

"The revelation made by the patient to the physician is, I believe, as sacred as the confession of a penitent to his priest?" Robert asked, gravely.

"Quite as sacred."

"A solemn confidence, to be violated under no circumstances?"

"Most certainly."

Robert Audley looked at the fire again. How much should he tell, or how little, of the dark history of his uncle's second wife?
