+It was in the spring of the year 1894 that all London was interested, and
+ the fashionable world dismayed, by the murder of the Honourable Ronald
+ Adair under most unusual and inexplicable circumstances.
+ The public has already learned those particulars of the crime which came
+ out in the police investigation, but a good deal was suppressed upon that
+ occasion, since the case for the prosecution was so overwhelmingly strong
+ that it was not necessary to bring forward all the facts.
+ Only now, at the end of nearly ten years, am I allowed to supply those
+ missing links which make up the whole of that remarkable chain.
+ The crime was of interest in itself, but that interest was as nothing to
+ me compared to the inconceivable sequel, which afforded me the greatest
+ shock and surprise of any event in my adventurous life.
+ Even now, after this long interval, I find myself thrilling as I think
+ of it, and feeling once more that sudden flood of joy, amazement, and increduli
+ty which utterly submerged my mind.
+ Let me say to that public, which has shown some interest in those glimpses
+ which I have occasionally given them of the thoughts and actions of a very
+ remarkable man, that they are not to blame me if I have not shared my knowledge
+ with them, for I should have considered it my first duty to do so, had
+ I not been barred by a positive prohibition from his own lips, which was
+ only withdrawn upon the third of last month.

+ There were points about this strange business which would, I was sure,

+ The drop was at least twenty feet, however, and a bed of crocuses in full

+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.
