Then he heard the deep, gruff voice of Dr. Blair Gaddon half laugh.

"Thanks a lot, Fenwick. You've taken a load off my mind. Goodbye, Miss Drake."

He heard Joan reply and then saw Dr. Fenwick usher the physicist out into the hall.

Trent rose as the two men approached.

"Why, hello, Trent," Dr. Fenwick said.

Trent nodded at the tall, white-coated figure of the famous gland specialist.

"Afternoon, doctor."

Fenwick smiled at him. "Don't tell me you're waiting to see me?"

Fred shook his head. "Not exactly. I was waiting to see Dr. Gaddon though. I was on my way out to the Proving Grounds and I happened to stop by and talk to Miss Drake." He turned to the physicist, a bulky man with firm, hard features, who moved his large body with an almost cat-like grace.

"I hope you don't mind, Dr. Gaddon. Possibly I can give you a lift back out to the Base. I'm covering the launching for my paper."
