Judy had noticed a change in Clarissa’s appearance. The shampoo had made her hair fluffy and bright.

“It’s like mine,” Honey said. “You sounded so strange over the telephone, Judy, when you asked me not to change the color of my hair. Why were you so afraid?”

“I like it the way it is. I guess that’s why.”

“Don’t you like mine?” Clarissa asked plaintively. “I didn’t use much of the shampoo. It hardly changed the color at all. It just brought out the golden highlights.”

“It’s lovely,” Judy had to admit. “It isn’t the product. It’s the way they advertise it that’s wrong. Peter calls ‘hidden sell’ advertisers thieves of the mind,” she continued, “but he says mind control can be used in another way.”

“This is interesting,” Horace said. “What is this other way our minds can be manipulated?”

“I—I’m not sure. Peter said something about talking pillows, but he may have been joking. I never heard of a pillow that talked.”

“Maybe it works like a Mamma doll,” Holly suggested, and everybody laughed.

“You tell us, Peter,” urged Judy.

“The pillows I spoke of,” Peter said, “are supposed to change a prisoner’s outlook on life by what is called sleep teaching. They contain taped messages that are fed into his subconscious mind while he sleeps. ‘You are filled with love and compassion’ is one. For all I know Lawson’s ‘Do good and gain good’ may be another. I don’t know how well they work. A study is being made.”
