Shall the world, then, be overrun by oysters? No, no; horrible! You'll convey all that is in your mind."

I left him full of the image of this magnificent intellect bab- bling like a foolish child. He had handed me the key, and with a happy thought I took it with me lest he should lock himself in. Mrs. Hudson was waiting, trembling and weeping, in the passage. Behind me as I passed from the flat I heard Holmes's high, thin voice in some delirious chant. Below, as I stood whistling for a cab, a man came on me through the fog.

"How is Mr. Holmes, sir?" he asked.

It was an old acquaintance, Inspector Morton, of Scotland Yard, dressed in unofficial tweeds.

Again the gentle murmur.

"Well, well, give him that message.
