For three months after taking over the practice I was kept very closely at work, and saw little of my friend Sherlock Holmes, for I was too busy to visit Baker Street, and he seldom went anywhere himself save upon professional business. I was surprised, therefore, when, one morning in June, as I sat reading the British Medical Journal after breakfast, I heard a ring at the bell, followed by the high, somewhat strident tones of my old companion’s voice.

“Ah, my dear Watson,” said he, striding into the room, “I am very delighted to see you! I trust that Mrs. Watson has entirely recovered from all the little excitements connected with our adventure of the Sign of Four.”

“Thank you, we are both very well,” said I, shaking him warmly by the hand.
