Ever since Herbie Jones had to be Annabelle's partner in the class dance contest, he's been acting weird, even going to the library instead of going fishing with his best friend, Raymond. Lucky for Herbie, Raymond is determined to get to the bottom of this mess.
Herbie's experiences in the third grade include finding bones in the boy's bathroom, wandering away from his class on their field trip, and being promoted to a higher reading group.
