He remained seated on the carpet while his wife lit the lamp and Dentry stood over him expressing his regret for what had happened. The doctor took no notice of Dentry. He put on a pair of gold-rimmed spectacles, and as soon as the lamp was lit put his head down so that his eyes were nearly level with the carpet. Then he got up briskly, brushing the dust from his clothes. “That will do,” he said. “We will be going now, and I will call on you, Mr. Dentry, to-morrow morning at ten o’clock, if that suits you.” “Certainly,” said Dentry. “Any time you like, Dr. Morning.” He seemed to me to be trying to cover with an attempt at swagger some real uneasiness. He kept on pointing out to the doctor how severe the test conditions had been. I was left alone when they had passed out into the hall, but the doctor came back almost immediately on the plea that he had left his spectacles. He turned to me at once. “Know these people well?” he said. “No; my acquaintance with Mrs. Dentry was a chance one.” “Done this kind of thing often before?” “Only once, on the one occasion when I was here before. Mrs. Dentry told me I was a medium.” “She would,” said the doctor grimly. “Well, you’re not. You’d better leave it.” “I will.” “I believe,” he said meditatively, “you are all right. Good night.” And he held out his hand to me. I followed him into the hall, and I noticed that he did not shake hands with Dentry. After the doctor and his wife had gone Dentry pressed me to wait for a few minutes to see his wife. She would be certain to return in a few minutes. I refused, and I also refused to let him escort me home. But, as it chanced, I had an escort all the same. For just outside in the street I happened to meet Minnie Saxe. “I didn’t know you went to that place, miss,” said Minnie Saxe severely. “What’s the matter with it?” I asked. And Minnie Saxe told me what was the matter with it. * * * * * * After breakfast next morning I sat and thought it over. Minnie Saxe and her father had been employed as caretakers at 32 Hanford Gardens. Her father had been also employed to repaint some of the rooms. Thus Minnie Saxe knew that the wainscot in the recess on the left of the fireplace in the front room was removable. It was impossible for anyone in the front room to detect this. On that side it appeared to be tightly nailed and solid. But anyone in the back room could slide a couple of bolts and find a way open into the front room. Also, nobody knew how Mr. and Mrs. Dentry made their money. Also, Mr. Dentry drank. And it was Minnie Saxe’s belief that they were engaged in the manufacture of false coin.
