"Yes, he has," replied her brother, turning suddenly towards me. "From the first I knew by whose hand she died, but was unable to act. You will understand, when I say that the villain was a member of our Circle, and that it was believed my wife was removed because she had accidentally discovered that an attempt was to be made at the Winter Palace. Such, however, was the report to the Executive, and the murder was looked upon as a commendable precaution." "Did not the Circle know it was your wife?" "No, I had kept my marriage a secret. The murderer was ignorant of our relationship, otherwise he would not have dared to commit the crime and report it to the Executive." "Then you are absolutely certain as to his identity?" I said, breathlessly. "Yes. At first I could not discover the motive, but since the confession of the servant it is plain he wished to obtain possession of the money, and placed the fatal emblem upon her in order to deceive us and secure our aid in concealing his guilt." "You have given the police his name!" exclaimed Vera, anxiously, "quick! tell us who he is." "What!" I ejaculated, in surprise, "are you, too, in ignorance of the real culprit?" "Quite; Boris has refused to disclose his identity," she said, quietly, in a tone of annoyance. "No," replied the Russian, bitterly. "There will be time enough when the police have hunted him down. Hitherto I have been powerless. I dare not denounce him lest he should divulge my connection with the plots, the inevitable result of which would have been my exile to the mines. Now, however, I fear nothing. He has destroyed the only one I loved, and shall suffer the penalty!" he added, fiercely. "But why not tell us?" I argued. "Surely we may know upon whom rests the guilt?" "Let the matter remain at present," he said, petulantly. "When the time arrives I shall be prepared to prove that which will send him to the gallows. Not only did he take my wife's life, but he also committed a second murder in order to hide the first--" "Another?" I cried. "Yes. Since my poor wife's maid, Jane Maygrove, returned from Australia and made her confession, I have discovered something even more strange. It seems that Jane had a sister Nell, very similar in feature, and previous to her departure abroad she told this sister all that had happened at Bedford Place on the fatal night. Needless to say, Nell traced the murderer and made excellent use of her information, inasmuch as she levied blackmail upon him to a considerable extent, he, of course, believing her to be the witness of his crime. She had married a man named Grey, and the pair lived upon the money she succeeded in extorting from the murderer. For some time this went on, until one night she was discovered in a court off Drury Lane, stabbed in the neck, and with the seal upon her--" "Why, that was the woman who was murdered on the night following my return from Russia!" I remarked, in amazement.
