WINNER: BEST ONLINE ONLY AUDIO DRAMA (BBC AUDIO DRAMA AWARDS)
People’s history, fantasy and high drama. The winning entry was outstanding in every respect:  a complex, gripping narrative made visible through three-dimensional characters in believable relationships, some fine acting, and a superbly orchestrated soundscape which never overdoes the atmospherics or signposting of changes in time and place. Above all, it manages its historical and fantastical elements seamlessly and, for a brief period, time is suspended for the listener.
