Sir Arthur Conan Doyle: The Return of Sherlock Holmes

1. The Adventure of the Empty House. (continued)

All day I turned these facts over in my mind, endeavouring to hit upon some theory which could reconcile them all, and to find that line of least resistance which my poor friend had declared to be the starting-point of every investigation. I confess that I made little progress. In the evening I strolled across the Park, and found myself about six o'clock at the Oxford Street end of Park Lane. A group of loafers upon the pavements, all staring up at a particular window, directed me to the house which I had come to see. A tall, thin man with coloured glasses, whom I strongly suspected of being a plain-clothes detective, was pointing out some theory of his own, while the others crowded round to listen to what he said. I got as near him as I could, but his observations seemed to me to be absurd, so I withdrew again in some disgust. As I did so I struck against an elderly deformed man, who had been behind me, and I knocked down several books which he was carrying. I remember that as I picked them up I observed the title of one of them, "The Origin of Tree Worship," and it struck me that the fellow must be some poor bibliophile who, either as a trade or as a hobby, was a collector of obscure volumes. I endeavoured to apologize for the accident, but it was evident that these books which I had so unfortunately maltreated were very precious objects in the eyes of their owner. With a snarl of contempt he turned upon his heel, and I saw his curved back and white side-whiskers disappear among the throng.

My observations of No. 427, Park Lane did little to clear up the problem in which I was interested. The house was separated from the street by a low wall and railing, the whole not more than five feet high. It was perfectly easy, therefore, for anyone to get into the garden, but the window was entirely inaccessible, since there was no water-pipe or anything which could help the most active man to climb it. More puzzled than ever I retraced my steps to Kensington. I had not been in my study five minutes when the maid entered to say that a person desired to see me. To my astonishment it was none other than my strange old book-collector, his sharp, wizened face peering out from a frame of white hair, and his precious volumes, a dozen of them at least, wedged under his right arm.
