Sherlock Holmes: The Sign Of Four

by Sir Arthur Conan Doyle

Adapted for the Stage by Nick Lane

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

Seen by over 50,000 people in 70 towns and cities across the UK, The Netherlands and China, The Sign of Four is Sir Arthur Conan Doyle’s epic second Sherlock Holmes tale, a breathtaking yarn brought to life in this spectacular new stage adaptation which premiered in September 2018. Crammed full of adventure, romance, comedy and of course one or two rather brilliant deductions, The Sign of Four will be streamed free of charge on Youtube from Sunday 5 to Wednesday 15 July.

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.
