The doctor was silent a moment, and threw his smoked-out cigarette away.
"I tell you this," he said at last, "as a sort of testimonial, recommendation, what you will: I came here as a stranger to you; you have received me with very cordial hospitality, and I present," he added, "my credentials."
Harry rose, and held out his hand.
"They are extremely satisfactory," he said. "And now for my dose and bed. You sleep in my uncle's sitting room, I think you said. I hope they have made you comfortable."
"I have everything," said the doctor. "By the way, speaking of your friend Mr. Langham, I may tell Mr. Francis that he has left, if I think it wise?"
"Certainly, if you wish."
"That he has gone to London?" suggested the doctor casually.
"As a matter of fact he has gone to his father's house for a few days, down near Sevenoaks. Lord Langham, you know."
"Ah, yes," said Dr. Armytage. "Good-night, my dear Lord Vail. I am convinced you will sleep well."
