Cherub series of books by Robert Muchamore

The Cherub series is a group of spy novels for teenagers written by Robert Muchamore which revolve around a top-secret branch of the British Security Service called CHERUB, which employs bright children, predominantly orphans, under the age of 17, as intelligence agents. They are trained to slip under adult radar and discover information that sends criminals to jail because, unlike adult-spies, they are unlikely to be suspected of anything. For official purposes, these children do not exist.
