nine o'clock
By six o'clock in the evening , two hours after the jury had brought in their verdict against a person or persons unknown , I had completed my work , and was in a position to state that two of the five large prints made on the window-glasses , and the three on the bowl , were made by the left hand of Marlowe ; that the remaining three on the window and the two on the drawer were made by his right hand . By eight o'clock I had made at the establishment of Mr. H. T. Copper , photographer , of Bishopsbridge , and with his assistance , a dozen enlarged prints of the finger-marks of Marlowe , clearly showing the identity of those which he unknowingly made in my presence and those left upon articles in his bedroom , with those found by me as I have described , and thus establishing the facts that Marlowe was recently in Manderson 's bedroom , where he had in the ordinary way no business , and in Mrs. Manderson 's room , where he had still less . I hope it may be possible to reproduce these prints for publication with this despatch . At nine o'clock I was back in my room at the hotel and sitting down to begin this manuscript . I had my story complete . I bring it to a close by advancing these further propositions : that on the night of the murder the impersonator of Manderson , being in Manderson 's bedroom , told Mrs. Manderson , as he had already told Martin , that Marlowe was at that moment on his way to Southampton ; that having made his dispositions in the room , he switched off the light , and lay in the bed in his clothes ; that he waited until he was assured that Mrs. Manderson was asleep ; that he then arose and stealthily crossed Mrs. Manderson 's bedroom in his stocking feet , having under his arm the bundle of clothing and shoes for the body ; that he stepped behind the curtain , pushing the doors of the window a little further open with his hands , strode over the iron railing of the balcony , and let himself down until only a drop of a few feet separated him from the soft turf of the lawn . All this might very well have been accomplished within half an hour of his entering Manderson 's bedroom , which according to Martin he did at about half-past eleven .
