In this wickedly funny sequel to MI5 and Me, it is the 1950s, and reluctant typist and spy's daughter Lottie has had the bad luck to fall in love with Harry, a handsome if frustrated young actor, who has been press-ganged into the family business as an undercover agent in the Communist hotbed of British theatre. Together the young lovers embark on a star-studded adventure through the glittering world of theatre - but between missing files, disapproving parents, and their own burgeoning creative endeavours, life is about to become very complicated indeed.
