"Puts me in mind of a story," began Shadow. "At a school——"
"No stories just now!" cried Dave. "I want to know who did this?"
"I saw some burdock burs yesterday," said Polly Vane. "Little Sammy Bilderman had them."
"Yes, and he gave them to Nat Poole," declared Chip Macklin. "I saw him do it."
"That explains it!" cried Dave.
"Explains what?" asked several of the others.
"Why Poole and Plum didn't show themselves while the racket was going on in Haskers's room. They came in here and fixed us up."
"It must be so," said Phil, "for I know my bed was all right before."
Dave leaped noiselessly to the door and threw it open. Nobody was outside, but he heard a door at a distance close softly.
"Somebody was out there. He just ran off," he declared.
