“The Bat, eh?” he muttered, then, changing his tone, “You knew about this hidden room, Wells?” he shot at the Doctor. “Yes.” The Doctor bowed his head. “And you knew the money was in the room?” “Well, I was wrong, wasn’t I?” parried the Doctor. “You can look for yourself. That safe is empty.” The detective brushed his evasive answer aside. “You were up in this room earlier tonight,” he said in tones of apparent certainty. “No, I couldn’t _get_ up!” the doctor still insisted, with strange violence for a man who had already admitted such damning knowledge. The detective’s face was a study in disbelief. “You know where that money is, Wells, and I’m going to find it!” This last taunt seemed to goad the Doctor beyond endurance. “Good God!” he shouted recklessly. “Do you suppose if I knew where it is, I’d be here? I’ve had plenty of chances to get away! No, you can’t pin anything on me, Anderson! It isn’t criminal to have known that room is here.” He paused, trembling with anger and, curiously enough, with an anger that seemed at least half sincere. “Oh, don’t be so damned virtuous!” said the detective brutally. “Maybe you haven’t been upstairs but—unless I miss my guess, you know who was!” The Doctor’s face changed a little. “What about Richard Fleming?” persisted the detective scornfully. The Doctor drew himself up. “I never killed him!” he said so impressively that even Bailey’s faith in his guilt was shaken. “I don’t even own a revolver!” The detective alone maintained his attitude unchanged. “You come with me, Wells,” he ordered, with a jerk of his thumb toward the door. “This time I’ll do the locking up.” The Doctor, head bowed, prepared to obey. The detective took up a candle to light their path. Then he turned to the others for a moment. “Better get the young lady to bed,” he said with a gruff kindliness of manner. “I think that I can promise you a quiet night from now on.” “I’m glad you think so, Mr. Anderson!” Miss Cornelia insisted on the last word. The detective ignored the satiric twist of her speech, motioned the Doctor out ahead of him, and followed. The faint glow of his candle flickered a moment and vanished toward the stairs. It was Bailey who broke the silence. “I can believe a good bit about Wells,” he said, “but not that he stood on that staircase and killed Dick Fleming.” Miss Cornelia roused from deep thought. “Of course not,” she said briskly. “Go down and fix Miss Dale’s bed, Lizzie. And then bring up some wine.” “Down there, where the Bat is?” Lizzie demanded. “The Bat has gone.” “Don’t you believe it. He’s just got his hand in!” But at last Lizzie went, and, closing the door behind her, Miss Cornelia proceeded more or less to think, out loud.
