118 literature and crime records unique, violin-player, boxer, swordsman, lawyer, and self-poisoner by cocaine and tobacco. Those, I think, were the main points of my analysis."

Holmes grinned at the last item. "Well," he said, "I say now, as I said then, that a man should keep his little brain-attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber-room of his library, where he can get it if he wants it. Now, for such a case as the one which has been submitted to us to-night, we need certainly to muster all our resources. Kindly hand me down the letter K of the American Encyclopædia which stands upon the shelf beside you. Thank you. Now let us consider the situation, and see what may be deduced from it. In the first place, we may start with a strong presumption that Colonel Openshaw had some very strong reason for leaving America. Men at his time of life do not change all their habits, and exchange willingly the charming climate of Florida for the lonely life of an English provincial town. His extreme love of solitude in England suggests the idea that he was in fear of some one or something, so we may assume as a working hypothesis that it was fear of some one or something which drove him from America. As to what it was he feared, we can only deduce that by considering the formidable letters which were received by himself and his successors. Did you remark the post-marks of those letters?"

"The first was from Pondicherry, the second from Dundee, and the third from London."

"From East London. What do you deduce from that?"

"They are all seaports. That the writer was on board of a ship."

"Excellent. We have already a clew. There can be no doubt that the probability—the strong probability—is that the writer was on board of a ship. And now let us consider another point. In the case of Pondicherry, seven weeks elapsed between the threat and its fulfilment, in Dundee it was only some three or four days. Does that suggest anything?"
