Five Get Into a Fix (পেপারব্যাক)

Julian, Dick, George and Anne feel that their Christmas is ruined because of their illness. It seems that Timmy is the only one among them who seems to be having fun. But when their neighbour offers them a holiday in Wales, they begin to feel better. However, this is not just a simple holiday. They get lost and find their way to a large and strange old building called Old Towers on the top of the lonely hill. This building is creepy, something is going on inside and the Five decide to investigate.
