"Doctor," said Chambers, "you're the least sociable man I've ever known. What do you do to enjoy yourself?"

"I work," said Craven. "I find it interesting."

"You must. You even begrudge the time it takes to talk with me."

"I won't deny it. What do you want this time?"

Chambers swung about to face him squarely across the desk. There was a cold look in the financier's gray eyes and his lips were grim.

"Craven," he said, "I don't trust you. I've never trusted you. Probably that's no news to you."

"You don't trust anyone," countered Craven. "You're watching everybody all the time."

"You sold me a gadget I didn't need five years ago," said Chambers. "You outfoxed me and I don't hold it against you. In fact, it almost made me admire you. Because of that I put you under a contract, one that you and all the lawyers in hell can't break, because someday you'll find something valuable, and when you do, I want it. A million a year is a high price to pay to protect myself against you, but I think it's worth it. If I didn't think so, I'd have turned you over to Stutsman long ago. Stutsman knows how to handle men like you."

"You mean," said Craven, "that you've found I'm working on something I haven't reported to you."

"That's exactly it."
