CHERUB: The Sleepwalker - Robert Muchamore

The ninth title in the number one bestselling CHERUB series! James is getting into trouble on campus, while Lauren has an air crash to investigate ...An airliner explodes over the Atlantic leaving 345 people dead. Crash investigators suspect terrorism, but they're getting nowhere. A distressed twelve-year-old calls a police hotline and blames his father for the explosion. It could be a breakthrough, but there's no hard evidence and the boy has a history of violence and emotional problems. Only CHERUB agents can unearth the truth. They're trained professionals with one essential advantage: adults never suspect that children are spying on them. For official purposes, these children do not exist.
