The room in which he received his patients was as bright and as well appointed as everything else in the establishment. A handsome walnut writing-table was lightly strewn with medical books and papers, relieved by a handsome china bowl full of roses. The patient’s chair was luxuriously cushioned with yellow silk, and the doctor’s own chair was a handsome one upholstered in tooled morocco leather. There was only one bookcase, and its appearance was more suited to a drawing-room than a professional man’s study. The frame was richly inlaid with ornamental woods, and the glass doors were protected by gilt wires. A small marble group of Eros and Psyche stood on the top, flanked by Chinese dragons. Elsewhere the walls of the room were hung with charming water-colours, most of them of a rather sensuous description, depicting youths and maidens bathing in pools, and scenes of love and jealousy. Tarleton took in every detail with one of those swift, searching looks of his which seemed to penetrate to some inner meaning beneath the surface of all he saw. Finally, his eye rested on the corner in which a safe about three feet high, painted to look like oxydized silver, was clamped on a supporting stand of ebony. “You have locked the safe, I see. Where are the keys?” The sudden demand agitated the nervous butler. “Miss Sarah has them,” he stuttered. “At least she took them away when she locked up the safe. Perhaps she’s given them to her mother--to Mrs. Weathered.” Sir Frank opened his eyes. I think we all did. Somehow it seemed incongruous that the founder of the Domino Club should be a married man. “Is there a Mrs. Weathered then?” “Why, yes, sir.” Simmons showed as much surprise as we had. “Would you like to see her, Sir Frank?” He seemed rather eager to get away and fetch his mistress to deal with us. The consultant restrained him by an imperative gesture. “One moment, if you please. You haven’t told us what happened after you had found the safe open. Did you go to call Mrs. Weathered?” “I should have gone, sir, but Miss Sarah came down and found us looking into the safe. So I left it to her.” Again the man made a movement as if to escape, and again the specialist arrested him. “What brought her down? Did she know what had happened?” Simmons seemed honestly confused. “I really can’t tell you, sir. I suppose one of the servants must have gone upstairs and told her. They were all about.” Tarleton nodded. “Go on. When she came in what did she do?” “She was rather angry sir, at first. She thought the doctor had come home in a great hurry to fetch something for someone who was ill, and had rushed off again, and forgotten to lock the safe and take his keys. She said we had no business to look inside in his absence. And she locked the safe herself, and sent the policeman away, saying no doubt Dr. Weathered would be back again presently. But that was more than four hours ago, and there’s been no sign of him yet, sir.”
