Benjamin and Rosanna Fitton are the husband and wife team behind the number-one hit podcast They Walk Among Us ®. The podcast started in September 2016, focusing on crime in the UK — delving into the crimes that are close to home, the criminal who sleeps beside you, lives next door, or delivers your newspaper. The podcast has won a British Podcast Award for best true crime podcast and a Lovie Award for best entertainment podcast. The couple wrote the book They Walk Among Us available through Virgin Books.

They Walk Among Us has been praised by The Guardian who called the show "a cult hit", The Financial Times referred to it as "sharply written", The Evening Standard praised the "expertly understated storytelling", and Newstatesman labelled it "the mysterious true crime podcast that'll keep you up at night".
