"Meanwhile, Mr. Hatch had called my attention to the burglary of St. George's apartments. One reading of that convinced me that it was Willis who did this. Why? Because burglars don't burst in doors when they think anyone is inside; they pick the lock. Knowing, too, Willis's insane jealousy, I figured that he would be the type of man who would go there to kill St. George if he could, particularly if he thought the girl was there.
"Thus it happened that I was not the only one to think that St. George knew where the girl was. Willis, the one most interested, thought she was there. I questioned Miss Stanford mercilessly, trying to get more facts about the young man from her which would bear on this, trying to trick her into some statement, but she was loyal to the last.
"All these things indicated several things. First, that Willis didn't actually know where the girl was, as he would have known had he killed her; second, that if she had disappeared with a man, it was St. George, as there was no other apparent possibility; third, that St. George would be with her or near her, even if he had killed her; fourth, the pistol shot through the arm had brought on again a mental condition which threatened his entire future, and now as it happens has blighted it.
"Thus, Miss Field and St. George were together. She loved Willis devotedly, therefore she was with St. George against her will, or she was dead. Where? In his rooms? Possibly. I determined to search there. I had just reached this determination when I heard St. George, violently insane, had escaped from the hospital. He had only one purpose then--to get to the woman. Then she was in danger.
"I reasoned along these lines, rushed to the artist's apartments, found Willis there wounded. He had evidently been there searching when St. George returned, and St. George had attacked him, as a madman will, and with the greater strength of a madman. Then I knew the madman's first step. It would be the end of everything for him; therefore the death of the girl and his own. How? By poison preferably, because he would not shoot her--he loved beauty too much. Where? Possibly in the place where she had been all along, the closet, carefully padded and prepared to withstand noises. It is really a padded cell. I have an idea that the artist, sometimes overcome by his insane fits, and knowing when they would come, prepared this closet and used it himself occasionally. Here the girl could have been kept and her shrieks would never have been heard. You know the rest."
The Thinking Machine stopped and arose, as if to end the matter. The others arose, too.
"I took you, Mr. Mallory, because you were a detective, and I knew I could force a way into the apartments which I imagined would be locked. I think that's all."
"But how did the girl get there?" asked Hatch.
"St. George evidently asked her to come, possibly to pose again. It was a gratification to the girl to do this--a little touch of vanity caused her to pose in the first place. It was this vanity that Willis was fighting so hard, and which led to his threats and his efforts to kill St. George. Of course the artist was insane when she came; his frantic love for her led him to make her a prisoner and hold her against her will. You saw how well he did it."
There was an awed pause. Hatch was rubbing the nap of his hat against his sleeve, thoughtfully. Detective Mallory had nothing to say; it was all said. Both turned as if to go, but the reporter had two more questions.
