The Sleepwalker

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.
