[1] The Find-Outers (Fatty, Larry, Daisy, Pip, Bets and Buster the dog) are desperate for a new mystery to investigate.
While they wait, Fatty has been using his newly learned skill of ventriloquism for pranks, especially against his nemesis Mr Goon, the village policeman.
The gang investigate and determine that Mr Fellows must have run away carrying a mysterious bundle, while the burglar was breaking in.
To create a distraction, Fatty throws a sack of rocks in the river saying it belongs to Fellows and escapes.
The gang has a setback when the doll's clothes are stolen, which they presume is by the burglar who ransacked Fellows' home.
