This has attracted many would be bounty hunters, fuelled by countless rumours of buried treasure and of course ghostly goings on. The abbey has always resisted giving up its secrets as though protected by some invisible force. Its secret remains buried with the spirits of the monks - until now Three children, staying with their grandparents for a week in October, are drawn to the mystery of the abbey and embark on a journey to learn the secret buried by the monks 800 years ago. Will they succeed in their quest or will they be thwarted? On their trail are treasure seekers, government agents and a man with a moustache.
