NO GIRLS says the sign on the door of The Wizard Private Eye clubhouse, but Marigold and Gussie and Rosie are determined, one might say possessed, with joining. The boys are baffled when a funny little bearded man gives Snitch a coded message. Later they scuffle with three funny little bearded men--the girls in disguise, readers will realize--who prove in the course of the exchange that they will make valuable club members. The boys end up begging them to join, and Marigold accepts for the girls when Wizard agrees to call the club the WIZMAR Private Eyes. With sexism out of the way, maybe the kids can start working on democracy--but they don't seem about to. Bonsall's cute kids zip through their paces, but the story is just inept politics.
