A boy becomes involved in an art heist when his father leaves home, leaving him in charge of the family.
Dylan Hughes is the only lad living in his tiny Welsh town. He helps out in his family's failing garage, managing the petrol log and keeping track of every single vehicle - including the mysterious convoy of lorries that trundles up the misty mountainside one day.
Dylan Hughes is more interested in Ninja Turtles than in the Renaissance artists they are named after. Even when he discovers priceless artwork stashed down the disused slate mines of his tiny Welsh village, Dylan would still prefer a pizza-eating, party-loving mutant turtle to a painting.
Then Dad leaves home and, overnight, nine-year-old Dylan must become man of the household - and boss of the failing family business. A masterpiece worth a mint might just be what they all need...
Book banded for guided reading by the Institute of Education - humorous novel / inspired by a press cutting describing how, during WWII, the treasured contents of London's National Gallery were storied in Welsh slate mines
