"Open the windows--all of them, then help me," commanded the scientist.
As Detective Mallory and Hatch turned to obey the instructions, The Thinking Machine took the revolver from the inert fingers of the artist. Then Hatch and Mallory returned and together they lifted the unconscious forms toward a window.
"It's Grace Field," said the reporter.
In silence for half an hour the scientist labored over the unconscious forms of his three patients. The detective and reporter stood by, doing only what they were told to do. The wind, cold and stinging, came pouring through the windows, and it was only a few minutes until the chloroform odor was dissipated. The first of the three unconscious ones to show any sign of returning comprehension was Victor Willis, whose presence at all in the apartments furnished one of the mysteries which Hatch could not fathom.
It was evident that his condition was primarily due to the wounds on his head--two of which bled profusely. The chloroform had merely served to further deaden his mentality. The wounds were made with the butt of the revolver, evidently in the hands of the artist. Willis's eyes opened finally and he stared at the faces bending over him with uncomprehending eyes.
"What happened?" he asked.
"You're all right now," was the scientist's assuring answer. "This man is your prisoner, Detective Mallory, for breaking and entering and for the attempted murder of Mr. St. George."
Detective Mallory was delighted. Here was something he could readily understand; a human being given over to his care; a tangible thing to put handcuffs on and hold. He immediately proceeded to put the handcuffs on.
"Any need of an ambulance?" he asked.
"No," replied The Thinking Machine. "He'll be all right in half an hour."
