These few inquiries proved, however, to be a more lengthy proceeding than Holmes had imagined, for he did not return to the inn until nearly nine o’clock. He was pale and dejected, stained with dust, and exhausted with hunger and fatigue. A cold supper was ready upon the table, and when his needs were satisfied and his pipe alight he was ready to take that half comic and wholly philosophic view which was natural to him when his affairs were going awry. The sound of carriage wheels caused him to rise and glance out of the window. A brougham and pair of grays, under the glare of a gas-lamp, stood before the doctor’s door.

“It’s been out three hours,” said Holmes; “started at half-past six, and here it is back again. That gives a radius of ten or twelve miles, and he does it once, or sometimes twice, a day.”

“No unusual thing for a doctor in practice.”
