The Mystery of the Haunted Farm by Elys Dolan
Strange and spooky things are happening down on the farm, and Farmer Greg knows exactly who to call - Ghosthunters! The three little pigs are the best guys for the job, a specialist team of Ghosthunters equipped with the latest in ghost-hunting gadgets. But when the Phantom Finder 5000 fails to recognise any paranormal activity AT ALL, the pigs realise all is not quite as it seems. . . and there's certainly something suspicious about the mysterious chicken coop up on the hill . . . could that be a werepuppy?
