The window in her own room and one of the windows in Mrs Villiers’ room were both locked, and the open window had a table in front of it, so that anyone entering would very probably knock it over, and thus awaken the sleepers. On the other hand, no one could have entered in at the door, because they would not have had time to escape before the crime was discovered. So it was clearly shown that Miss Marchurst must have been alone in the room when the crime was committed. Now to look into her past life--it was certainly not a very creditable one. M. Vandeloup had sworn that she had been his mistress for over a year, and had taken the poison manufactured by himself out of his private desk. Regarding M. Vandeloup’s motives in preparing such a poison he could say nothing. Of course, he probably did it by way of experiment to find out if this colonial grown hemlock possessed the same poisonous qualities as it did in the old world. It was a careless thing of him, however, to leave it in his desk, where it could be obtained, for all such dangerous matters should be kept under lock and key. To go back, however, to Miss Marchurst. It had been proved by M. Vandeloup that she was his mistress, and that they quarrelled. She produced this poison, and said she would kill herself. M. Vandeloup persuaded her to abandon the idea, and she subsequently left him, taking the poison with her. She then went on the stage, and subsequently left it in order to live with Mrs Villiers as her companion. All this time she still had the poison, and in order to prevent her losing it she put half of it into another bottle. Now this looked very suspicious, as, if she had not intended to use it she certainly would never have taken such trouble over preserving it. She meets M. Vandeloup at a ball, and, hearing that he is going to marry Mrs Villiers, she loses her head completely, and threatens to poison herself. M. Vandeloup tries to wrench the poison from her, whereupon she flings it into the garden. This bottle has disappeared, and the presumption is that it was picked up. But if the jury had any idea that the poison was administered from the lost bottle, they might as well dismiss it from their minds, as it was absurd to suppose such an improbable thing could happen. In the first place no one but M. Vandeloup and Miss Marchurst knew what the contents were, and in the second place what motive could anyone who picked it up have in poisoning Mrs Villiers, and why should they adopt such an extraordinary way of doing it, as Miss Marchurst asserted they did? On the other hand, Miss Marchurst tells M. Vandeloup that she still has some poison left, and that she will kill Mrs Villiers sooner than see her married to him. She declares to M. Vandeloup that she will kill her, and leaves the house to go home with, apparently, all the intention of doing so. She comes home filled with all the furious rage of a jealous woman, and
