One mistake, two mistakes… The case of the wooden fish

Stephen and Renee, along with their dogs Ping and Pong, are back on the case! Something strange is happening in the neighborhood: bizarre items have started to disappear – an overly realistic Halloween doll (brrr!), a decoration from the school fence that all the kids made by hand, a beautiful mailbox. And at night, someone stole the neighbor's garden gnome. Additionally, a weapon was found left behind by someone in the school library! Stephen continues to count mistakes – both his own and others', and skillfully uses them to conduct the investigation! Will he manage to identify the cunning culprit?
