Hartson Brant came down the stairs, dressed in a suit, with white shirt and tie. Rick stared at him. "Going somewhere, Dad?"

"Yes. Parnell Winston has disturbed me deeply, with the implications of his theory. I'm going to pay a call on an old friend in Newark, an associate of Chavez. I want to explore some of the electrophysiological background of his hypothesis. I won't be very late. Is there any gas in the car?"

"Almost full," Scotty said.

The boys went on upstairs into their adjoining rooms. For a few minutes Rick tinkered with his camera equipment, then he went back down to the library and searched the shelves for something to read. He finally settled on W. Grey Walter's The Living Brain and carried it back up to his room.

He sat down in the old leather armchair and manipulated buttons on one arm. The light brightened to reading intensity, and the back tilted to the most comfortable position. He had wired the chair himself, and it fit him perfectly. He settled down to read.

Time passed as he lost himself in the clear, exciting descriptions in Dr. Walter's book. He heard a bell ring downstairs, but paid no attention. Then Scotty stuck his head in the door. "Rick! Your mother's calling you."

Rick sat up swiftly. It was true, and his mother had urgency in her voice.

He dropped the book and ran to the stairs, going down them three at a time. A strange, dark-haired man was standing in the hallway, and his mother, Barby, and Jan were waiting for him with strained white faces.

"Your father has been hurt," Mrs. Brant said with false calm. "He's on this gentleman's houseboat!"
