Charlie’s mother is about to be taken as a witch. She’ll surely die – and Charlie too. With the aid of Balthazar, his mother’s cat, Charlie escapes – but now he finds himself in another time, Northumbria four centuries earlier – and a different kind of danger! He’s arrived for the prizegiving at the annual Feast of the Book. But just as the winner is about to be announced there’s news of a different kind. One of the abbey monks has been found dead – horribly murdered. Charlie and his new-found friend Lady Marian are drawn into investigating the crime – but there’s more to it than that. At the peril of their own lives can they solve a runic riddle and find the abbey’s missing treasure? “The Riddle of the Poisoned Monk” is a fast-paced medieval mystery set in an ancient castle – with potfuls of potions, dark secrets and missing treasure. Sarah Matthias has written a thrilling adventure with lively characters that will appeal to 9-12’s.
