"I expected that, Doctor, and a car is already on its way to pick you up. I'll meet you at Langley Field where a plane is already being tuned up and will be ready to take off by the time we get there." "Good work, Carnes. I'll see you at the field." * * * * * A car was waiting for Carnes and Dr. Bird when the Langley Field plane slid down to a landing at Atlanta. At the penitentiary, Dr. Bird went direct to the infirmary where Karuska had been confined. As he entered, he shot a keen glance around and gave an exclamation of satisfaction. "Look at the windows, Carnes," he cried. Carnes went over to the nearest window and moistened his finger tip and applied it experimentally to the glass. The moisture produced no effect, for the glass of the windows was permanently clouded as was that of the doctor's laboratory. "Whatever happened in my laboratory the night before last was repeated here last night with a similar object," said the doctor. "The object there was to steal a gun model; here it was to steal a man who could construct a full-sized gun from the model. I understand that one of the guards escaped the fate which overtook the rest of the persons in the infirmary?" "Not altogether, Doctor," replied the warden. "I think that his mind is somewhat affected, for he tells a wild yarn and insists on trying to wear a goldfish bowl on his head. I have him under observation in the psychopathic ward." Dr. Bird shot a scornful glance at the warden. "'There are none so blind as those who will not see'," he murmured. "By all means, I wish to see him," he went on aloud. "Will you have him brought here at once, please?" * * * * * The warden nodded and spoke to one of the attendants. In a few moments a tall, fair-haired young giant stood before the doctor. Dr. Bird pushed back his unruly shock of black hair with his fingers, those long slim mobile fingers which alone betrayed the artist in his make-up, and shot a piercing glance from his black eyes into the blue ones, which returned the gaze unabashed. "What is your name?" he asked. "Bailley, sir." "You were on guard here last night?" "Yes, sir. I was detailed as a special guard over No. 9764." "Tell me in your own words just what happened. Don't be afraid to speak out; I'm not going to disbelieve you; and above all, tell me everything, no matter how unimportant it may seem to you. I'll judge the importance of things for myself. I'm Dr. Bird of the Bureau of Standards." The guard's face lighted up at the doctor's words. "I've heard of you, Doctor," he said in a relieved tone, "and I'll be glad to tell you everything. At ten o'clock last night, I relieved Carragher as special guard over No. 9764. Carragher reported that the prisoner was somewhat restless and hadn't been asleep as yet. I sat down about fifteen feet from his bed and prepared to keep an eye on him until I was relieved at six o'clock this morning.
