Ever since he made his first appearance in A Study In Scarlet, Sherlock Holmes has enthralled and delighted millions of fans throughout the world. Now Arthur Conan Doyle's complete works – four novels and five collections of short stories – has been brought to life by Stephen Fry, a lifelong fan of Doyle's detective fiction, in this The Definitive Collection. In addition, Stephen has written and narrated nine insightful, intimate and deeply personal introductions to each title. Part 2: The Sign of the Four Sherlock Holmes is bored and case-less, and relieving his boredom by alternating morphine and cocaine. Enter the charming Miss Mary Morstan, with whom Watson is instantly smitten. She requests the assistance of Holmes and Watson to solve the mysterious disappearance of her father, and the subsequent invitation to 'have justice' by an anonymous letter writer. Holmes and Watson happily accompany her to see the anonymous letter writer; only to become deeply embroiled in a mystery concerning treasure, murders, India, escaped convicts and small savages with poisoned blowpipes.
