A terrorist doesn't let strangers into her flat because they might be undercover police or intelligence agents, but her children bring their mates home and they run all over the place
The terrorist doesn't know that one of these kids has bugged every room in her house, made copies of all her computer files and stolen her address book.
The kid works for CHERUB
CHERUB agents are aged between 10 and 17. They live in the real world, slipping under adult radar and getting information that sends criminals and terrorists to jail.
