As the heavy door closed behind him Lucian descended the steps and looked thoughtfully at the grim mansion, which was tenanted by so mysterious a person. He could make nothing of Berwin--as he chose to call himself--he could see no meaning in his wild words and mad behaviour; but as he walked briskly back to his lodgings he came to the conclusion that the man was nothing worse than a tragic drunkard, haunted by terrors engendered by over-indulgence in stimulants. The episode of the shadows on the blind he did not attempt to explain, for the simple reason that he was unable to find any plausible explanation to account therefor. "And why should I trouble my head to do so?" mused Lucian as he went to bed. "The man and his mysteries are nothing to me. Bah! I have been infected by the vulgar curiosity of the Square. Henceforth I'll neither see nor think of this drunken lunatic," and with such resolve he dismissed all thoughts of his strange acquaintance from his mind, which, under the circumstances, was perhaps the wisest thing he could do. But later on certain events took place which forced him to alter his determination. Fate, with her own ends to bring about is not to be denied by her puppets; and of these Lucian was one, designed for an important part in the drama which was to be played. Mrs. Margery Kebby, who attended to the domestic economy of Berwin's house, was a deaf old crone with a constant thirst, only to be assuaged by strong drink; and a filching hand which was usually in every pocket save her own. She had neither kith nor kin, nor friends, nor even acquaintances; but, being something of a miser, scraped and screwed to amass money she had no need for, and dwelt in a wretched little apartment in a back slum, whence she daily issued to work little and pilfer much. Usually at nine o'clock she brought in her employer's breakfast from the Nelson Hotel, which was outside the Square, and while he was enjoying it in bed, after his fashion, she cleaned out and made tidy the sitting-room. Berwin then dressed and went out for a walk, despite Miss Greeb's contention that he took the air only at night, like an owl, and during his absence Mrs. Kebby attended to the bedroom. She then went about her own business, which was connected with the cleaning of various other apartments, and only returned at midday and at night to lay the table for Berwin's luncheon and dinner, or rather dinner and supper, which were also sent in from the hotel. For these services Berwin paid her well, and only enjoined her to keep a quiet tongue about his private affairs, which Mrs. Kebby usually did until excited by too copious drams of gin, when she talked freely and unwisely to all the servants in the Square. It was to her observation and invention that Berwin owed his bad reputation.
