“There is a room which is used as a morning-room at Lachine. This faces the road and opens by a large glass folding-door on to the lawn. The lawn is thirty yards across, and is only divided from the highway by a low wall with an iron rail above it. It was into this room that Mrs. Barclay went upon her return. The blinds were not down, for the room was seldom used in the evening, but Mrs. Barclay herself lit the lamp and then rang the bell, asking Jane Stewart, the housemaid, to bring her a cup of tea, which was quite contrary to her usual habits. The Colonel had been sitting in the dining-room, but hearing that his wife had returned he joined her in the morning-room. The coachman saw him cross the hall and enter it. He was never seen again alive.
