Sherlock Holmes: The Sign of the Four - Sir Arthur Conan Doyle

Sherlock Holmes: The Sign of the Four by Sir Arthur Conan Doyle “…the individual man is an insoluble puzzle…” One of the earliest and most thrilling Sherlock Holmes novels, The Sign of the Four plunges the great detective into a labyrinth of secrets, betrayal, and revenge in Victorian London. When Miss Mary Morstan receives a series of mysterious letters from an unknown benefactor, she turns to Sherlock Holmes and Dr John Watson for help uncovering the truth behind her father’s unexplained disappearance. What begins as a curious enquiry quickly spirals into a dangerous investigation tied to a long-buried conspiracy. Holmes soon finds himself tracking the trail of the legendary Agra Treasure, a fortune stolen years before and bound to a pact between four men—a pact sealed by greed, loyalty, and murder. The pursuit leads through fog-shrouded streets, along the River Thames, and toward a relentless adversary: a wooden-legged man driven by vengeance. Combining deduction, action, exotic intrigue, and emotional depth, The Sign of the Four is a cornerstone of classic detective fiction and an essential chapter in the Sherlock Holmes canon. A must-read for fans of Victorian mysteries, literary classics, and the enduring brilliance of Sherlock Holmes.
