The Mystery of the Missing Necklace

Fatty's disguises are better than ever. No one recognises him as a balloon seller, or as the old man in the village. Burglaries are going on and the police are baffled. It's a new mystery for the Five Find-Outers and Dog!

The fifth book is paced well, chock full of descriptions for a change, and very engrossing. The mystery itself starts around chapter six as usual, after a bit of fun with Fatty's disguises, but the necklace of the title isn't announced as missing until the end of chapter seventeen, leaving a mere four chapters to find it.
