Choco rat

Our resident rat not content with trying to break in the kithchen cupbpard to get at the dog food took a fancy to the Royal (as in Prince Charles) chocolates in Marys handbag. It went for the hazelnut truffle.
Mary wants to poison it. Being an animal lover I won't hear of it, however if I can't persuade it to move to a nearby chocolate factoy shortly the mad Tajiki axeman might by called into action. His aim is swift and true.
