Fifteen-year-old Jasmine feels very alone. She's never known her father, her mother is always working and her best friend Tess has moved away. Channelling all her energy into trying to be like the gorgeous and fortunate Sadie, Jasmine's own life begins to seem like a pale imitation of Sadie's. When one day Jasmine's father's face appears on Crimewatch, Jasmine welcomes the chance to put her detective skills into practise, but finds herself drawn into a world of mystery, danger and intrigue, where she stands to uncover more than she ever dreamed of.
