A special Valentine's Day card helps third-grader Harry overcome his fear of climbing the rope in gym class.

Nearly every kid in Room 3B is trying to get picked for the South School Safety Patrol Squad--especially Harry. Harry wants a star badge just like his grandpa's, so he works extra hard to be the perfect student: hanging up his jacket neatly, organizing the crayons in rainbow order, and--his favorite part--cleaning up sticky noodles off the floor after lunch.

Third-grader Harry thinks of a way to patch up a conflict with his schoolmate Mary and include his friends in a fun detective case with rewards for everyone, including Grandpa.

They even claim he's cheating. Harry insists he's playing fair and square. Doug doesn't know what to think! He must prove his best friend is innocent...
