Mr. Patton was examining my broken arm and paid no attention. The man let himself down into the pit under the staircase. When he straightened, only his head rose above the steps. Although I was white with pain to the very lips I laughed hysterically. “The head!” I cried. Mr. Patton swore under his breath. They half led, half carried me into the library. Mr. Reed was there, with a detective on guard over him. He was sitting in his old position, bent forward, chin in palms. In the blaze of light he was a pitiable figure, smeared with dust, disheveled from what had evidently been a struggle. Mr. Patton put me in a chair and dispatched one of the two men for the nearest doctor. “This young lady,” he said curtly to Mr. Reed, “fell into that damnable trap you made in the rear staircase.” “I locked off the staircase—but I am sorry she is hurt. My—my wife will be shocked. Only I wish you’d tell me what all this is about. You can’t arrest me for going into a friend’s house.” “If I send for some member of the Smythe family will they acquit you?” “Certainly they will,” he said. “I—I’ve been raised with the Smythes. You can send for any one you like.” But his tone lacked conviction. Mr. Patton made me as comfortable as possible, and then, sending the remaining detective out into the hall, he turned to his prisoner. “Now, Mr. Reed,” he said. “I want you to be sensible. For some days a figure has been seen in the basements of the various Beauregard houses. Your friends, the Smythes, reported it. Tonight we are on watch, and we see you breaking into the basement of the Smythe house. We already know some curious things about you, such as dismissing all the servants on half an hour’s notice and the disappearance of the French governess.” “Mademoiselle! Why, she——” He checked himself. “When we bring you here tonight, and you ask to be allowed to go upstairs and prepare your wife, she is locked in. The nurse is missing. We find her at last, also locked away and badly hurt, lying in a staircase trap, where some one, probably yourself, has removed the steps. I do not want to arrest you, but, now I’ve started, I’m going to get to the bottom of all this.” Mr. Reed was ghastly, but he straightened in his chair. “The Smythes reported this thing, did they?” he asked. “Well, tell me one thing. What killed the old gentleman—old Smythe?” “I don’t know.” “Well, go a little further.” His cunning was boyish, pitiful. “How did he die? Or don’t you know that either?” Up to this point I had been rather a detached part of the scene, but now my eyes fell on the tongs beside me. “Mr. Reed,” I said, “isn’t this thing too big for you to handle by yourself?” “What thing?” “You know what I mean. You’ve protected yourself well enough, but even if the—the thing you know of did not kill old Mr. Smythe you cannot tell what will happen next.” “I’ve got almost all of them,” he muttered sullenly. “Another night or two and I’d have had the lot.”
