Agent Z
Agent Z is a fictitious character in a series of four comical children's books written by British author Mark Haddon, better known for his 2003 novel The Curious Incident of the Dog in the Night-time. In the first published versions of the books Haddon also did the artwork for the covers and a number of illustrations inside (the cover pictures were changed for later editions). The Agent Z series is set in the present day in an unnamed British city.

Agent Z is not an actual living person in the books but a 'front' used by three schoolboys, Ben, Barney and Jenks, who have been friends for years, and who also call themselves the Crane Grove Crew. The mission of Agent Z is to wreak havoc on the unsuspecting and the deserving in a battle against boredom. The missions take the form of practical jokes, and with the culprits usually leaving a Z mark (like Zorro) on the scene of the prank. The Crane Grove Crew have their own secret base in a boarded-up, derelict park-keeper's cottage on the edge of the park near where they live. With a few exceptions that emerge in the stories, no-one knows of the identity of Agent Z, and the boys say they have made a pledge of secrecy never to reveal the identity of Agent Z.
In 1996 Agent Z and the Penguin from Mars was adapted for television by the BBC.
