But when Mrs. Balmer entered the room the following morning to straighten it up she found several innovations. There were four kerosene lamps in the room. They stood on small rickety tables, one in each corner. And there was a new electric light bulb in the central fixture. Mrs. Balmer took note of these things with a professional eye but said nothing. Idiosyncrasies are to be expected of the amputated folk who seek out lonely tenement bedrooms for a home. * * * * * A week later, however, Mrs. Balmer spoke to the man. "You burn your light all night," said Mrs. Balmer, "and while I have no objection to that, still it runs up the electric light bill." The man agreed that this was true and answered that he would pay $1 extra each week for the privilege of continuing to burn the electric light all night. Nothing happened. Yet Mrs. Balmer, when she had time for such things as contemplation, grew curious about the man in the back room. In fact she transferred her curiosity from the Japanese female impersonator on the second floor and the beautiful and remarkably gowned middle-aged woman on the first floor to this man who kept four kerosene lamps and an electric bulb burning all night on the third floor. For some time Mrs. Balmer was worried over the thought that this man was probably an experimenter. He probably fussed around with things as an old crank does sometimes, and he would end by burning down the house or blowing it up--accidentally. But Mrs. Balmer's fears were removed one evening when she happened to look down the gloomy hallway and notice that this man's door was open. A gay, festive illumination streamed out of the opened doorway and Mrs. Balmer paid a social call. She found her roomer sitting in a chair, reading. Around him blazed four large kerosene lamps. But there was nothing else to notice. His eyes were probably bad, and Mrs. Balmer, after exchanging a few words on the subject of towels, transportation and the weather, said good-night. But always after that Mrs. Balmer noticed that the door remained open. Open doors are frequent in rooming-houses. People grow lonely and leave the doors of their cubby holes open. There is nothing odd about that. Yet one evening while Mrs. Balmer stood gossiping with this man in the doorway she noticed something about him that disturbed her. She had noticed it first when she looked in the room before saying hello. Mr. Crawford was sitting facing the portieres that covered the folding doors that partitioned the room. The portieres were a very clever ruse of Mrs. Balmer. Behind them were screwed hooks and these hooks functioned as a clothes-closet.
