man with some amount of self-importance and a certain air of command. You must have observed the way in which he held his head and swung his cane. A steady, respectable, middle-aged man, too, on the face of him—all facts which led me to believe that he had been a sergeant."
"Wonderful!" I ejaculated.
"Commonplace," said Holmes, though I thought from his expression that he was pleased at my evident surprise and admiration. "I said just now that there were no criminals. It appears that I am wrong—look at this!" He threw me over the note which the commissionaire had brought.
"Why," I cried, as I cast my eye over it, "this is terrible!"
"It does seem to be a little out of the common," he remarked, calmly. "Would you mind reading it to me aloud?"
This is the letter which I read to him,—
"My dear Mr. Sherlock Holmes,—
"There has been a bad business during the night at 3, Lauriston Gardens, off the Brixton Road. Our man on the beat saw a light there about two in the morning, and as the house was an empty one, suspected that something was amiss. He found the door open, and in the front room, which is bare of furniture, discovered the body of a gentleman, well dressed, and having cards in his pocket bearing the name of 'Enoch J. Drebber, Cleveland, Ohio, U.S.A.' There had been no robbery, nor is there any evidence as to how the man met his death. There are marks of blood in the room, but there is no wound upon his person. We are at a loss as to how he came into the empty house; indeed, the whole affair is a puzzler. If you can come round to the house any time before twelve, you will find me there.

"Gregson is the smartest of the Scotland Yarders," my friend remarked; "he and Lestrade are the pick of a bad lot. They are both quick and energetic, but conventional—shockingly so. They have their knives into one another, too. They are as jealous as a pair of professional beauties. There will be some fun over this case if they are both put upon the scent."
I was amazed at the calm way in which he rippled on. "Surely there is not a moment to be lost," I cried; "shall I go and order you a cab?"
"I'm not sure about whether I shall go. I am the most incurably lazy devil that ever stood in shoe leather—that is, when the fit is on me, for I can be spry enough at times."
"Why, it is just such a chance as you have been longing for."
"My dear fellow, what does it matter to me? Supposing I unravel the whole matter, you may be sure that Gregson, Lestrade, and Co. will pocket all the credit. That comes of being an unofficial personage."
"But he begs you to help him."
"Yes. He knows that I am
