“When you have eliminated the impossible, whatever remains, however improbable, must be the truth!”

Following their hugely successful tour of The Hound of the Baskervilles, Colin Baker (Doctor Who, The Brothers) and Terry Molloy (The Archers, Doctor Who) return as the legendary Sherlock Holmes and Dr Watson in another gripping mystery from Sir Arthur Conan Doyle.

When Miss Morstan receives a mysterious pearl each year from an unknown sender, Holmes and Watson are drawn into a chilling case of murder, greed and revenge. A missing fortune, a locked room, and a map to hidden treasure — can the world’s greatest detective uncover the truth behind The Sign of Four before it’s too late?

Presented by Crime and Comedy Theatre Company as a radio play live on stage, this clever and atmospheric production transforms the theatre into a 1940s radio studio, complete with live sound effects and a dash of comedy.
