Halloween should be fun, but Beast is in big trouble. He was working really hard on his spelling homework when Ms. Rooney read The Halloween Horror to the class. Then she told the students to write to the author. "Say anything," Matthew suggests, and Beast does. He tells the author he loved the dog in the book. And he even invites the author to come to school's Halloween parade, never dreaming he might accept. Then Beast finds out therewas no dog in the book. And now, to make Beast's Halloween really horrible, guess who's coming to the Polk Street Halloween parade? And guess who's been assigned to be his helper?
