I was finishing this little analysis of the case when the door was opened and the austere figure of the great dermatologist was ushered in. But for once his sphinx-like features had relaxed and there was a warm humanity in his eyes. He strode up to Colonel Emsworth and shook him by the hand.
"It is often my lot to bring ill-tidings, and seldom good," said he. "This occasion is the more welcome. It is not leprosy."

Yes, Mr. Holmes, the coincidence is a remarkable one. But is it coincidence? Are there not subtle forces at work of which we know little? Are we assured that the apprehension, from which this young man has no doubt suffered terribly since his exposure to its contagion, may not produce a physical effect which simulates that which it fears? At any rate, I pledge my professional reputation— But the lady has fainted! I think that Mr. Kent had better be with her until she recovers from this joyous shock."
THE ADVENTURE OF THE MAZARIN STONE
It was pleasant to Dr. Watson to find himself once more in the untidy room of the first floor in Baker Street which had been the starting-point of so many remarkable adventures. He looked round him at the scientific charts upon the wall, the acid-charred bench of chemicals, the violin-case leaning in the corner, the coal-scuttle, which contained of old the pipes and tobacco. Finally, his eyes came round to the fresh and smiling face of Billy, the young but very wise and tactful page, who had helped a little to fill up the gap of loneliness and isolation which surrounded the saturnine figure of the great detective.
