Sherlock Holmes - The Sign of Four

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

Crammed full of adventure, romance, comedy and of course one or two rather brilliant deductions, The Sign of Four is Sir Arthur Conan Doyle’s epic second Sherlock Holmes tale, a breath-taking yarn brought to life in this spectacular new stage adaptation.

When Mary Morstan arrives at 221B, Baker Street to request help with the mystery of her missing father, Holmes takes the case and together with his companion Dr Watson enters a murky world of deception and trickery, unravelling a complex plot involving murder, corruption and stolen jewels.

Don’t miss Blackeyed Theatre’s stunning world premiere of Sherlock Holmes: The Sign of Four. Original live music, stylish theatricality and magical story-telling combine for an unforgettable theatrical experience. The game’s afoot!
