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.
