“Agatha Christie’s mysterious 11 day disappearance in 1926 gripped the nation and set off one of the biggest manhunts ever mounted. In desperation, Britain’s most famous crime writers of the time, Sir Arthur Conan Doyle and Dorothy L. Sayers, were drafted in to help the search. As they took matters into their own hands with their contrasting methods of detection, this was the beginning of crime’s most unlikely investigative partnership: Sayers and Conan Doyle, together at last and on the hunt for Agatha Christie.”

The programme also features a live piano performance from Rupert Cross as he arranged and accompanied Anna Maxwell Martin singing.
