“I beg your pardon,” said the other, absently.

“Did he make an appointment?”

“An appointment? Oh, no! He turned up suddenly in the evening after dinner when I wasn’t expecting him. I took him up here and examined him, and he left me somewhere about ten o’clock, I should think.”

“May I ask what was the result of your examination?”

“Why do you want to know?”

“It might illuminate—well, conjecture as to his subsequent conduct,” said Parker, cautiously. This story seemed to have little coherence with the rest of the business, and he wondered whether coincidence was alone responsible for Sir Reuben’s disappearance on the same night that he visited the doctor.

“I see,” said Sir Julian. “Yes. Well, I will tell you in confidence that I saw grave grounds of suspicion, but as yet, no absolute certainty of mischief.”

“Thank you. Sir Reuben left you at ten o’clock?”

“Then or thereabouts. I did not at first mention the matter as it was so very much Sir Reuben’s wish to keep his visit to me secret, and there was no question of accident in the street or anything of that kind, since he reached home safely at midnight.”

“Quite so,” said Parker.
