Set in the leafy suburbs of 1950s London, the Beresfords find themselves in need of some adventure in their lives. With Tommy undertaking a variety of business opportunities, and Tuppence trying to dissuade him, the couple find themselves in the wrong place at the right time to solve a mystery - or two - and perhaps save someone's life. They are about to enter a world of espionage and skulduggery guided by Tommy's mysterious Uncle, Major Carter. It is a world which will prove easier to enter than to leave.
