Egg and Binky McNaughton are thrilled to be named class managers for the School Store and when they take over, the little hole-in-the-wall shop becomes a top-notch retail store. Sales are way up and things are going great until money starts disappearing from the till.

Only two employees have access to the money: Mary Beth Adamson a member of the elite High Five Club and Angela Hardy, Egg's girlfriend. Since the High Five's are all from wealthy homes, the finger seems to be pointing at Angels. She would never do that to Egg-or would she? Can Egg discover the thief before his relationship with Angela is ruined forever?

Will Egg's girlfriend turn out to be a criminal?
