"I wonder if the doctor ever had such a blinkin' ass in his house before!" said the amiable gentleman to himself as he shut his bed-room door behind him. Looking at myself in the glass with a kind of chastened complacence, I decided that the man who could perceive in Mr. Hobhouse any reminiscence of the mysterious young stranger of six months ago would have a singularly piercing eye. At the same time it was a sobering experience to gaze at that black-bearded gentleman, with his hair parted in the middle and brushed low down over his forehead, and his foolish looking pince-nezs, and reflect that there was no artificial difference between him and the vanished Roger Merton save those eye-glasses and a little hair dye. That was my own face, and my own hair, and, I presumed, my own natural latent idiocy blinking behind those glasses. I turned away from the mirror with mingled feelings. As the hour was not late (early to bed being part of the cure), I put on my dressing gown and sat down to smoke and chew the cud of my evening's conversation with Dr. Rendall. The more I saw of him, the more favourably on the whole the man impressed me. He was a gentleman and seemed a good fellow. Being a bachelor with outdoor tastes and an easygoing disposition, it was not at all impossible to understand his choosing the estate of his family to settle down on, isolated though it was. Certainly one could not honestly charge it against him as a suspicious circumstance. By far the most interesting discovery was his obvious dislike to Mr. O'Brien. Not once but several times he had shown it in the course of our talk. He conveyed the suggestion moreover that the man had oppressed him in some way and that it was a relief to have got rid of him. In view of the fact that he had been so anxious to secure another resident patient, this seemed a little odd, and a theory began to take shape in my mind. Supposing O'Brien had in some way induced the doctor unwillingly to abet a treasonable scheme, that would account for his feelings very well, especially looking to O'Brien's unpleasing personality. But on the other hand, events had made it clear that treason was going on without O'Brien, so how could the doctor have got clear of it? And if he were still in it, this theory of his relations to his late patient was manifestly weak. "To bed!" said Thomas Sylvester to himself, after an hour of these reflections. "You are theorizing too soon." In the morning he was up betimes and downstairs a good ten minutes before he knew the doctor was likely to appear. Into the smoking room he went, shut the door carefully behind him, and made for the window. A grey and windy prospect met his eyes, but they scarcely glanced at it. Mr. Hobhouse had something else to think of. Twice or thrice he pulled the blind up and down, and minutely examined the string and the little brass pulley.
