“You are aware that I know, and have known all along, the present relations of my friend Treherne with your family?”

“I had rather not discuss that subject, Doctor Urquhart.”

“No, but it will account for my asking questions about Captain Treherne. He left me this morning in a state of the greatest excitement. And at his age, with his temperament, there is no knowing to what a young man may not be driven.”

“At present, I believe, to nothing worse than the Cedars, with my sister as his charioteer.”

“You are satirical.”

“I am exceedingly obliged to you.”

Dr. Urquhart regarded me with a sort of benignant smile, as if I were a naughty child, whose naughtiness partly grieved, and partly amused him.

“If, in warrant of my age and my profession, you will allow me a few words of serious conversation with you, I, in my turn, shall be exceedingly obliged.”

“You are welcome.”

“Even if I speak about your sister and Captain Treherne?”
