Close as was the intimacy which existed between the unhappy lady and her maid, Mrs. Layton retained so jealous a possession of these incriminating documents that Ida White was not able to lay her hands upon them. In the company of Eustace Rutland she was supping in Prevost's Restaurant on the night of the 25th of March. She had slipped away from Mrs. Layton's house, as she had often done before, to meet her young and foolish lover. She saw her master and Mabel enter the room, and observed Layton taking off his ulster. Then the idea suddenly entered her head that Eustace and she should personate her master and the young lady--with a full knowledge how deeply those two were compromised by their being together and arrive home before them, by which time, doubtless, Mrs. Layton would be asleep. She knew that under her pillow Mrs. Layton kept the documents which Eustace frantically desired to obtain, and the possession of which would make her, Ida White, his wife. If Mrs. Layton awoke and resisted while the forged bills were being abstracted, Eustace would be at hand to use force, if necessary; and it was principally from the wish to compromise her lover so deeply that he would not dare to break his promise to marry her that she determined to put her idea into execution. She knew that ordinarily Edward Layton kept the latch-key of the street door in the pocket of his ulster. She disclosed the scheme to Eustace, and threatened him with exposure if he did not do as she desired. It was she who took the ulster from the wall of the restaurant, and it was she who, secretly and expeditiously, assisted Eustace to put it on; then they stole out together and entered the carriage. Before acquainting Eustace with her design she had ascertained that Edward Layton's carriage was waiting for him and for Mabel. She trusted to her own resources to keep her master out of his house after she and Eustace had entered it.
Here a word is necessary as to the true meaning of Edward Layton's proceedings during the day and night of the 25th of March. Abandoned as were the hopes in which he and Mabel had once fondly indulged, she still relied upon his efforts to save her brother from harm. Eustace had lost heavily upon certain races. He had made a despairing appeal to her, and she called upon Layton to assist the erring lad. It was in the endeavor to discover Eustace that Edward Layton had driven from place to place to obtain from him the information necessary to rescue him from his peril. Mabel had, by letter, engaged to meet Edward Layton in Bloomsbury Square at ten o'clock on the night of that day, in order that he might relieve her anxiety with respect to her brother. How they met, and what transpired after they met, have been already sufficiently detailed.
Ida White's manœuvres were successful up to a certain point. She and Eustace entered the carriage, were driven home, and, unsuspected, obtained entrance into the house. The correspondence between Eustace and Mabel had been for some time conducted through the medium of the system of the Nine of Hearts, and it was either by an oversight or by accident that Eustace, during the drive from Prevost's Restaurant to Edward Layton's house, took from his own pocket one of these cards and let it drop into the pocket of the ulster. But when they were safely in Layton's house, and crept stealthily and noiselessly into Mrs. Layton's bedroom, they made the horrible discovery that Mrs. Layton, in a moment of frenzy, had emptied the bottle of poisonous narcotics, and had by her own will destroyed herself. The proof was at her bedside: When she had swallowed the fatal pills, the horror of the deed overwhelmed her. She summoned up sufficient strength to rise in her bed, to take paper and the pen from the inkstand, and before the death-agony commenced in her sleep, to write upon that paper the confession which fixed upon her the crime of suicide.
Having reached this point of the strange story, I demanded to know from Eustace Rutland what had become of that confession.
"Ida took possession of it," he said, "and I have not seen it from that moment to this."
"Why did you not come forward and make this public?" I cried.
"Because," was his reply, "Ida told me that, if what we had done became known, nothing could save us from the hangman."
"Did she obtain possession of the forged acceptances?"
"Yes."
"How was it that the tumbler from which the fatal draught was taken was on the mantle-shelf?"
