I kept my appointment at nine that night, and the Dentrys’ rather frowsy maid showed me into the room where I had been on the previous evening. Two men in evening dress stood by the fireplace. One was Dentry; the other was a short, solid-looking man with a closely clipped grey beard. At the table sat an elderly lady in black, with tight lips and a proud, disapproving face. Dentry thanked me for coming, and explained that his wife could not be present. “She is, in fact, taking some of my regular work in order that I may be free.” The grey-bearded man was introduced to me as Dr. Morning. The elderly lady, to whom I was not presented, was his wife. “The doctor and Mrs. Morning are acting for Mr. Wentworth Holding,” said Dentry. “They are here to find out whether we cheat. I admit the unfortunate necessity of such an examination, and I may add that I welcome it. How will you begin, Dr. Morning?” “With the walls.” “Certainly,” said Dentry. He changed his position and leaned against one of the panels. The doctor began with that panel, but neither there nor in the rest of his thorough examination of the room did he seem to come across anything of a suspicious character. This part of the business rather bored me. I wanted to get on and see what would happen. The doctor produced several straps with bells attached to them, and Mrs. Morning fastened a couple of these on my hands and wrists. She did this without speaking a word to me, and as she tightened the strap on my wrists she looked as if she wished they had been handcuffs. The doctor secured Dentry in a similar manner. If either he or I moved hand or foot the sound of the bells would betray us. The doctor, Dentry and myself took our seats at the table in the usual way. Mrs. Morning sat at a little distance. All the lights were put out, but there was an unlit candle on a little table beside Mrs. Morning, and she held a box of matches ready in her hand. Almost immediately Dentry asked, in a clear, loud voice, “Is there any spirit here present? From a far corner of the room came a low snarl as of some wild beast. “The spirit present,” said Dentry, “is an evil spirit. It will be safer not to go on with the sitting.” “We will go on, please,” said Dr. Morning. “Very well,” said Dentry. “I disclaim all responsibility.” “Of course,” said the doctor. There was distinctly a note of contempt in his voice. For a few slow minutes we went on sitting in silence, and then I heard a crash. Mrs. Morning struck a match and lit the candle at her side. I could see that the doctor had been thrown violently to the ground. “All right, all right,” he said to his wife. “I’m not hurt. Let me have a little more light, please.”
