The new police officer Clive is not nice—even the other police are afraid of him. Everything, even the dog, must have a receipt to prove there’s no stealing going on. Things without receipts are locked up. Of course, Theo’s family don’t have a receipt for anything, especially not their dog Sherlock. When Sherlock is caught, Theo makes a plan to get him back using cooking oil, a dog onesie and cunning—a plan so good that it reveals Clive’s true identity and gives him the comeuppance he deserves. Even Theo’s family are impressed. This criminally funny tale contains a break-in at the candy store, an interrogation and a super-smart plan—with comical commentary from the dog, who thinks his name is Shuddup Sherlock.
