“Mind you,” continued the man in the corner, after he had assured himself of my undivided attention, “all these details were unknown to the public at first. I have merely co-ordinated them, and told them to you in the actual sequence in which they occurred, so that you may be able to understand the subsequent events. “At the time—that is to say, on 3rd December, 1903—the evening papers only contained an account of what was then called ‘the mysterious outrage at Gastle Street, Portsmouth.’ A private gentleman was presumably assaulted and robbed in broad daylight, and inside a highly respectable house in a busy part of the city. “Mrs. Bowden, the landlady, was, as you may imagine, most excited and indignant. Her house and herself had been grossly insulted by this abominable outrage, and she did her level best to throw what light she could on this mysterious occurrence. “The story she told the police was indeed extraordinary, and as she repeated it to all her friends, and subsequently to one or two journalists, it roused public excitement to its highest pitch. “What she related at great length to the detective in charge of the case, was briefly this: “Captain and Mrs. Markham, it appears, arrived at 49, Gastle Street, on Wednesday afternoon, 2nd December, and Mrs. Bowden accommodated them with a sitting-room and bedroom, both on the ground floor. In the evening Mrs. Markham went out to dine with her brother, a Mr. Paulton, who is a well-known Portsmouth resident, but Captain Markham stayed in and had dinner alone in his sitting-room. “According to Mrs. Bowden’s version of the story, at about nine o’clock a stranger called to see Captain Markham. This stranger was obviously a foreigner, for he spoke broken English. Unfortunately, the hall at 49, Gastle Street, was very dark, and, moreover, the foreigner was attired in a magnificent fur coat, the collar of which hid the lower part of his face. All Mrs. Bowden could see of him was that he was very tall, and wore gold-rimmed spectacles. “‘He was so very peremptory in his manner,’ continued Mrs. Bowden, ‘that I had to show him in at once. The Captain seemed surprised to see him—in fact, he looked decidedly annoyed, I might say; but just as I was closing the door I heard the stranger laugh, and say quite pleasantly: “You gave me the slip, my friend, but you see I have found you out all right.”’ “Mrs. Bowden, after the manner of her class, seems to have made vigorous efforts to hear what went on in the sitting-room after that,” continued the man in the corner, “but she was not successful. Later on, however, the Captain rang and ordered whiskies and sodas. Both gentlemen were then sitting by the fire, looking quite friendly. “‘I took a look round the room,’ explained the worthy landlady, ‘and took particular notice that the jewel-case was on the table, with the lid open. Captain Markham, as soon he saw me, closed it very quickly.’
