It's half-term and the Five are going hiking through the woods and up the hills. But when Anne and Dick take a wrong turn, it leads them all straight into danger! An escaped convict is on the loose and passes a strange message to Dick by mistake. A stash of treasure has been hidden nearby - will they discover it before the prisoner strikes again?
