 Producer of the series Kerry Appleyard revealed that the concept for the show came from the creator and writer of the show Keith Brumpton who had the idea it would be fun to do a kids spy show and worked on the concept that kids find it very hard to keep secrets.MI5 and MI6 did not want the production team to use their names in the television programme but did allow them to use the name of the now defunct MI9 which back in World War II was in charge of covert operations in the UK and overseas and created various gadgets.Producer Kerry Appleyard thought that it was appropriate because the show has a lot of fantastic gadgets.
