The Director breathed heavily.

"Just who are these people, Dr. Brill?"

"They are all positives. Some of them are positive positives."

The Director made a small, strangling sound.

"If you don't mind, Dr. Brill—just what in the hell are positive positives?"

"Oh, I'm sorry. I had presumed you were familiar with my work."

"I'm a little vague about it."

"I see." Lucifer's expression showed intolerance for this cultural lag, but he condescended to explain.

There was an expression on the Director's face of a man trying to plod doggedly against a strong gale.

"Positives ..." he reminded, a little desperately.
