Satisfied with the result of his first investigation, Leger has settled back into his old life of chasing tabbies, playing with his Labrador room-mate, Bob, when they are alone and recreational catnip use. However, a burglar is at work in his street. Leger's curiosity leads him to witness the theft of three expensive tropical fish from his neighbour's home. Putting his personal feelings for the fish aside, Leger has to break the law himself and endure a white knuckle ride across town in his quest to track down the thief and he will stop at nothing to bring him to justice! This is the second story in The Leger Mysteries and sees the return of all the clowder and their unlikely friends.
