It was late evening when he took off the headpiece. A faint smile was on his lips as he closed the door of the room behind him.

He spent two hours more searching the stacks of the fairly ample library of the Institute. Then he returned to the hotel, and his smile was broader than ever as he entered the door. The psychiatrist, Dr. Spindem, was waiting for him in the lobby.

He arose and came forward, hand outstretched to greet Montgomery. His face was beaming professionally and his eyes scanned the major intently.

“I came as quickly as I could,” he said. “I told Colonel Dodge we couldn’t afford to endanger unnecessarily a man with your qualifications.”

Montgomery chuckled. “I can imagine what Dodge’s answer was!”

“What do you mean by that?” Spindem’s eyes sharpened their inspection.

“Nothing — particularly.”

“You mean you feel the colonel doesn’t appreciate you?” Spindem insisted.

“Something like that,” Montgomery agreed. “Would you like to come up to my room where we can talk?”

Spindem nodded. “Yes. I want to hear everything you’ve found out so far about this incredible, so-called Institute.”
