  • The four citadels - bunkers created in World War II in case of German invasion, which were expanded during the Cold War in case of nuclear attack - existed in real life. In the Behind the Scenes feature, James Goss said he created a fifth so he could set a story there without anybody "writing in to Big Finish saying 'ahhh, it can't be that one'."
  • This story was recorded on 22, 23, 25 and 26 October 2012.
