. "Ask them to let you go,
baby. Oil Pocket said he'd put you in a musical. You always did want to
hit the big time--"

"Not any more." She smoothed down her dress and patted up her hair.
"Well, I want to catch the rest of that lecture, hon. See you around if
you decide to stay."

He sat down morosely and watched her snake-hip toward the Center,
realizing that her seductive walk was no more than professional
conditioning. She had grown in some mysterious way, become more
serene--at peace.

He had wondered what catatonics got for their work. He knew now--the
slickest job of hypnotic flattery ever invented. That was _their_ pay.

But what did the pitchmen get in return?

Clocker put in a call for Barnes at the box office of the Center. Barnes
left a lecture for researchers from his planet and joined Clocker with
no more than polite curiosity on his paternal face. Clocker told him
briefly and bitterly about his talk with Zelda, and asked bluntly what
was in it for the aliens.

"I think you can answer that," said Barnes. "You're a scientist of a

"I think it can be stopped, yeah. But you birds act like you don't want
