Timmy is in disguise at the start of this book. His mum has banned him from his detective business – shut it down – dead.

What’s even worse is his weird cousins Merry and Larry have come to stay, leaving him sleeping on the floor between their beds in his room.

Mum decides that since Timmy isn’t wasting his time being a detective he will have so much more time on his hands, signing him up for piano lessons and taking him to an orthodontist – neither of which go well.

But through all these obstacles, a teacher strike (leading to an extended school year into his summer holidays!), Timmy finds himself a new headquarters, a way to increase business, and a crime that must be solved. His best friend Rollo Tookus has gone missing. Can he solve his most important crime to date?
