The Sign of the Four (Collector's Edition) (Laminated Hardback with Jacket) (Hardcover) (ISBN-13: 9781998736614)

A cryptic letter, a long-lost treasure, and a secret pact forged in blood-Sherlock Holmes and Dr. Watson are about to step into one of their most dangerous cases yet. When the intelligent and composed Mary Morstan arrives at 221B Baker Street, she brings a mystery wrapped in pearls and shadow-her missing father, a nameless benefactor, and a dark secret buried in the past. As Holmes unravels a tangled web of betrayal and revenge, the hunt takes them deep into London's underworld, where every clue leads to more peril. A desperate chase, a wooden-legged man, and whispers of an oath sworn in a distant land pull them toward a truth far stranger than they could have imagined.

Blending adventure, mystery, and psychological depth, The Sign of the Four cemented Sherlock Holmes as literature's most brilliant detective. Introduced during the height of Victorian fascination with crime and empire, the novel explores themes of colonialism, greed, and justice through an intricate case tied to India's past. Doyle's masterful storytelling and sharp deduction scenes shaped the modern detective genre, influencing countless writers and filmmakers. Beyond its thrilling mystery, the book deepened the relationship between Holmes and Watson, setting the stage for one of fiction's most iconic partnerships.
