The Sign of Four: Sherlock Holmes: Book #3

'How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?'

Enthralling, fast-paced and undeniably clever, The Sign of Four is Arthur Conan Doyle's second novel to star the iconic and unparalleled consulting detective, Sherlock Holmes.

When Miss Mary Morstan receives a series of mysterious gifts and a cryptic note, ten years after her father's sudden disappearance, she's at a loss of where to turn. Enter detective Sherlock Holmes and his trusted companion Dr John Watson, determined to solve the case. With nothing but a cryptic clue – a map of a fortress labelled as 'The Sign of Four' – Holmes is drawn into a complicated labyrinth of stolen treasure, secret pacts and profound betrayal. Racing against the clock, he is led to the opium dens of London and a decades-old conspiracy born within colonial India, unveiling a case that tests both his intellect and the heart of right-hand man. Dark and richly atmospheric, The Sign of Four blends deduction and danger into Holmes's most perilous exploits yet.
