The Case of the Psychic Hamster

There can be
only three in
the Freaky Joe Club
Those are the rules, set down by Freaky Joe himself in the big red book, slightly chewed on one corner and wrapped in a locked bicycle chain. The newest chapter of the Freaky Joe Club consists of Conor, Timmy, and Jack, and their mission is to solve crimes and fight evil in Ship's Cove, Texas -- if they can only convince anyone that there is evil in Ship's Cove.
The members of the Freaky Joe Club are back in school, but somehting strange is going on at the Edith R. Hammerrocker Elementary School. Why does the new principal hate the school's nickname? What is a Hammerrocker Hamster anyway? And what are those strange, brown creatures doing in the gym? For that matter, who was Edith R. Hammerrocker? And most of all...
WHO IS FREAKY JOE?
