"I don't know," was the frank reply. "She's been partly stupefied for days--ever since she disappeared, as a matter of fact. If her physical condition was as good as her appearance indicates she may recover. Now the hospital is the best place for her."
It was only a few minutes before two ambulances came and the three persons were taken away; Willis a prisoner, and a sullen, defiant prisoner, who refused to speak or answer questions; St. George raving hideously and cursing frightfully; the woman, beautiful as a marble statue, and colorless as death.
When they had all gone, The Thinking Machine went back into the bedroom and examined more carefully the little closet in which he had found the artist and Grace Field. It was practically a padded cell, relatively six feet each way. Heavy cushions of felt two or three inches thick covered the interior of the little room closely. In the top of it there was a small aperture, which had permitted some of the fumes of the chloroform to escape. The place was saturated with the poison.
"Let's go," he said, finally.
Detective Mallory and Hatch followed him out and a few minutes later sat opposite him in his little laboratory. Hatch had told a story over the telephone that made his City Editor rejoice madly; it was news, great, big, vital news.
"Now, Mr. Hatch, I suppose you want some details," said The Thinking Machine, as he relapsed into his accustomed attitude. "And you, too, Mr. Mallory, since you are holding Willis a prisoner on my say-so. Would you like to know why?"
"Sure," said the detective.
"Let's go back a little--begin at the beginning, where Mr. Hatch called on me," said The Thinking Machine. "I can make the matter clearer that way. And I believe the cause of justice, Mr. Mallory, requires absolute accuracy and clarity in all things, does it not?"
"Sure," said the detective again.
"Well, Mr. Hatch told me at some length of the preliminaries of this case," explained The Thinking Machine. "He told me the history of the picture; the mystery as to the identity of the model; her great beauty; how he found her to be Grace Field, a shop-girl. He also told me of the mental condition of the artist, St. George, and repeated the rumor as he knew it about the artist being heartbroken because the girl--his model--would not marry him.
