To run down and secure it was the work of a moment, and, as the passages were by no means dark, it was not difficult for him to find his way back to his own door. So, at least, he thought; but when he arrived there, and turned the handle, the door entirely refused to open, and he caught the sound of a hasty movement towards it from within. He had tried the wrong door, of course. Was his own room to the right or to the left? He glanced at the number: it was 13. His room would be on the left; and so it was. And not before he had been in bed for some minutes, had read his wonted three or four pages of his book, blown out his light, and turned over to go to sleep, did it occur to him that, whereas on the blackboard of the hotel there had been no Number 13, there was undoubtedly a room numbered 13 in the hotel. He felt rather sorry he had not chosen it for his own. Perhaps he might have done the landlord a little service by occupying it, and given him the chance of saying that a well-born English gentleman had lived in it for three weeks and liked it very much. But probably it was used as a servant’s room or something of the kind. After all, it was most likely not so large or good a room as his own. And he looked drowsily about the room, which was fairly perceptible in the half-light from the street-lamp. It was a curious effect, he thought. Rooms usually look larger in a dim light than a full one, but this seemed to have contracted in length and grown proportionately higher. Well, well! sleep was more important than these vague ruminations—and to sleep he went.
