The Famous Five are back solving three more puzzling mysteries:

Book 8 - Five Get into Trouble
Dick's been kidnapped, mistaken for someone else, and the Famous Five are frantic! Desperately, they track him down to a sinister old house in the middle of nowhere -- and he's safe and well! But just when they thought their troubles were over, the gang find themselves held captive and in terrible danger! Who will come for them now?

Book 18 - Five on Finniston Farm
There's a ruined castle on Finniston Farm, but only the dungeons remain -- and nobody knows where they are! The Famous Five are determined to find them -- and whatever is hidden in them -- but they are not alone. Someone else wants to know, too. The question is: can the Five get there first?

Book 21 - Five Are Together Again
The Famous Five are having great fun camping out near the home of a famous scientist. But they might have known there'd be a mystery to solve. When the scientist's important research papers go missing, he needs the gang's help to get them back! But how can the Five work out who took them? And why?
