A mysterious villain is tripping the poor, innocent students at Dizzie Day Elementary School. They’re tripping; they’re flipping; they’re flying through the air! Worst of all, they’re losing their homework as they fall. The whole town is in a frenzy searching for the boot-wearing culprit . . . until one student makes a startling confession.          With vivid illustrations—and plenty of clues for readers to do their own detective work—Gene Barretta has created a hilarious, creepy tale about the perils (and sometime rewards!) of following the crowd.
