"Let it be clearly understood," he said, "that I forbid that woman to be called by my name. I will see this matter through myself. I have known of such things before. This is a scheme to ruin the character of an honourable man. But I shall take immediate care to nip it in the bud. Is that a chambermaid in the passage? Come here, please. Have the goodness to ask the manager to come to this room immediately. Do not go, madam, nor you either, sir, until I speak to the manager." Mainwaring flung the Baedeker which he had been studying on a table. We heard some doors opened and some feet hurrying in our direction. Doubtless the chambermaid who had disappeared on Mainwaring's errand had already spread the news of our extraordinary story. When I heard people approaching I took the liberty to close the door of the room. "What are you doing that for, sir?" exclaimed Mainwaring, whose face was now almost purple with excitement. "Pray don't speak so loud," I replied, putting as much force and command into my voice as I possibly could. "I presume you do not wish the servants of the hotel to become acquainted with your private affairs." He glanced at me savagely, but did not say anything further. A moment later the manager's knock was heard. I opened the door to him. He came in, looking anxious and disturbed, and asked why he had been sent for. Mainwaring began to speak in an excited voice. "I have sent for you," he said, "to ask you to see that this man and woman leave the hotel immediately. They have forced their way into my room and have endeavoured to perpetrate a most disgraceful hoax upon me. This lady, whom I never saw before, has had the audacity to claim me as her husband. I wish you to understand clearly that both these people are impostors. They must leave this hotel immediately if you wish it to retain its character for respectability." The manager looked puzzled, as well he might. Mainwaring, although he showed symptoms of strong excitement, must have appeared perfectly sane to an ordinary observer. Poor Mrs. Mainwaring, white and trembling, stood up and looked at me to defend her. "This is a very extraordinary story," I said to the manager. "I will give you my version of it in another room." "Come," I said, turning to Mrs. Mainwaring. She put her hand into mine and I led her into the passage. The instant we left the room Mainwaring shut and locked the door. "That unfortunate gentleman is insane," I said to the manager of the hotel. "He must be watched, and on no account allowed to leave his bedroom without being followed." "That is all very well, sir," replied the man, "but I must have very good evidence of the truth of your statements before I can allow any pressure to be put on the gentleman who occupies No. 39. This is a very queer story, and Mr. Mainwaring showed no signs of insanity before you came. But, insane or not, it isn't to be supposed that he wouldn't know his own wife."
