“He’s that!” Delaney declared. “He and his brother the devil are one in sin. They’re lost spirits.”

“Now everybody,” said Drew, gathering in the group with his eyes, which were strangely bright. “Everybody keep very quiet for a minute. Let me think.”

“Sure and I will, Chief. I’m thinking I want to think, myself.”

Drew frowned at Delaney. He dropped his eyes and studied the prisoner’s hands. They were strangely white and remarkably small for a man who had labored at telephone-repairing. The detective’s glance rested on the ink-stained thumb. His mind swung with this thought to the footprints. Following the train he arrived at the first conclusion that an expert in telephony could devise most any kind of a practical method for opening a window or a ventilator. He dismissed this theory with a glance about the room. The ventilator was well-hidden and inaccessible to any one without a step-ladder. Considerable time devoted in climbing upon a chair and a case of jade ornaments might reach it, but the trouble-man had not been alone in the room when he inspected the telephone.

Drew went over the salient details of the Stockbridge tragedy. One fact stood out. The windows had been well locked. The sashes were covered with snow. A climber, even on the face of the house, would have difficulty in springing a catch by a secret method, raising the window and entering without leaving a track of some kind. He dismissed this supposition as untenable. He turned to Delaney, fully puzzled.

“Was there a climber’s set in that bag?” he asked sharply.

“I didn’t see any, Chief. I don’t think this fellow’s a climber. He ain’t built like one. His shoes are smooth on the bottom and his hands are all polished up around the nails. Looks to me, Chief, as if he might be able to pick most any kind of a lock.”

“The locks are out of the question!” snapped Drew. “I examined them. They’re not in line. Has anybody here any suggestions?”

Drew stared at the prisoner’s drawn, white face as he asked this question. “He wasn’t long in this part of the house,” said the captain. “The maid watched him. She thought perhaps he might take something.”

“Fosdick is to blame!” said Drew almost losing his temper. “He should have given strict orders at the door not to let anybody in till the case was settled. It’s all mixed up now. This man had ample opportunity to cover himself. A clever sneak could do most anything under your eyes without you seeing him operate. I suppose the only thing to do is to turn him over to Headquarters. He’ll get his!”
