Everyone knows Sherlock Holmes. Sir Arthur Conan Doyle created a unique literary character who has remained popular for over a century and is appreciated more than ever today. But what made this fictional character, dreamed up by a small-town British doctor in the 1880s, into such a lasting success, despite the author’s own attempt to escape his invention? In , Swedish author and Sherlock Holmes expert Mattias Boström recreates the full story behind the legend for the first time. From a young Arthur Conan Doyle sitting in a Scottish lecture hall taking notes on his medical professor’s powers of observation to the pair of modern-day fans who brainstormed the idea behind the TV sensation , from the publishing world’s first literary agent to the Georgian princess who showed up at the Conan Doyle estate and altered a legacy, the narrative follows the men and women who have created and perpetuated the myth. It includes tales of unexpected fortune, accidental romance, and inheritances gone awry, and tells of the actors, writers, readers, and other players who have transformed Sherlock Holmes from the gentleman amateur of the Victorian era to the odd genius of today. Told in fast-paced, novelistic prose, is a singular celebration of the most famous detective in the world—a must-read for newcomers and experts alike.
