Once error, two mistakes ... The case of wooden fish (#2)

Annotation to the book "times error, two mistakes ... A case of wooden fish.
Stephen and Rene, and with them the dogs Ping and Pong again in the case! Something something was happening in the district: strange things began to disappear-an overly natural Halloween doll (BRRR!), Decoration from a school fence that all children did with their own hands, a beautiful mailbox. And at night someone stole a neighboring garden gnome. Yes, and in the school library found a weapon left by someone! Stephen continues to consider mistakes - both his own and strangers, and masterfully conducts an investigation with the help of them! Will he be able to calculate a skilled attacker?
