"Who? Who taught you?"
"The Pipers."
"Who? The Pipers? Who are the Pipers?"
There was no answer.
"Mr. Bradshaw, who are the Pipers?"
After a long, agonized pause, the heavy lips parted. "They live in the woods...."
Harris snapped off the projector, and the lights came on. He and Cox blinked. "That was all I could get," Harris said. "But I was lucky to get that. He wasn't supposed to tell, not at all. That was the thing they all promised not to do, tell who taught them to become plants. The Pipers who live in the woods, on Asteroid Y-3."
"You got this story from all twenty?"
"No." Harris grimaced. "Most of them put up too much fight. I couldn't even get this much from them."
Cox reflected. "The Pipers. Well? What do you propose to do? Just wait around until you can get the full story? Is that your program?"
