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.
"That blind certainly does not come down at a touch," he said to himself, "and there is not a sign of its having been repaired within the last few years. Therefore it did not drop accidentally six months ago."

THE TEST
That afternoon, as the weather had cleared somewhat, Dr. Rendall proposed walking over to his cousin's house and presenting Mr. Hobhouse to the laird and his daughter. This ordeal had to be undergone sooner or later, so I decided I had better fall in with his suggestion and get it over at once. Besides, it was an obvious part of my programme to make a great deal of outdoor exercise a principal feature of Mr. Hobhouse's cure, and I felt bound to agree at once with any proposal to take a walk. We had taken the precaution, by the way, of telling the doctor beforehand of my limp (caused by a motoring accident when I was at the wheel in a condition I should not have been in) and assuring him that the surgeon encouraged exercise to complete the cure. So off we set for the "big house."
On the way the doctor gave his guest a certain amount of general information concerning the people they were going to meet, but as Mr. Hobhouse happened to know it already, it need not be chronicled here.
As the pair approached the weather beaten old mansion, looking now in its true setting against the wintry sky, Thomas Sylvester became acutely conscious of the return of a familiar sensation. It was, in fact, precisely the sensation which one Roger Merton had enjoyed when waiting for his cue to step from dim obscurity into the flare of the footlights on the first night of a new drama. Would his old acquaintances accept Mr. Hobhouse without question as an entire stranger? If he spied so much as one suspicious questioning glance, his whole scheme was exploded.
We were shown into the drawing room, and to my great relief Mr. Rendall was the first to appear, for I felt I could stand the scrutiny of Jean's bright eyes a deal more readily if I had once got into the swing of talk with her father. In his eye there was certainly no trace of question. With his dry and formidable courtesy he greeted Mr. Hobhouse and in a minute or two they were talking away in that friendly fashion which Mr. Hobhouse was pleased to notice people fell into very readily with him. And small wonder, for the creature was so grossly affable, and (if I say it myself) so infernally plausible.
