Then she rose and rather noisily locked the door; she hoped that Dr. Macrae would hear her, and so come and attend to what he considered his duty when at home. But Dr. Macrae was lying on the sofa smoking and dreaming of Lady Cramer's beauty, and that night he did not care who locked the door. The huge key turned, the bolts slipped into their places, and she went upstairs, full of indignation at her brother-in-law. She could not understand his mood; for she remembered that in spite of the gravity of the subjects on which they had disagreed there was an air of yawning and boredom about him. It was evident to her that they were intruding on some subject much more interesting. At that hour she was trying to find out what really filled her with forebodings. Little wondering, wandering thoughts about some change in her brother-in-law had flitted for two weeks in and out of her consciousness. But all his slight deviations from the natural and usual were as nothing in comparison with the change she perceived this night. Then, in the midst of her trifling suppositions, there was suddenly flashed across her mind a few words she never doubted: "_He is in love with Lady Cramer! He intends to marry her!_" The clue had been given and she followed it out. She thought she now saw clearly why Macrae was so determined to marry Marion to Allan Reid. He was going to marry into the Cramer family himself, and it would be most disturbing and confusing if Marion did the same. It would be too much. Though there was no legal barrier, there was a positive social one, so vigilantly deterrent, indeed, that she was sure no such case had ever been brought to the Minister's notice; and then she speculated a while as to what would have been his action under the circumstances.
