From the bestselling author of The Butchering Art and The Facemaker comes the astonishing true story of Joseph Bell, the Scottish surgeon whose extraordinary talent for detection inspired Sherlock Holmes

Edinburgh, 1878. A medical student squeezes into the Royal Infirmary's packed operating theatre, eager to catch a glimpse of his celebrated professor-a man whose uncanny powers of observation blur the line between diagnosis and detective work.

That man was Joseph Bell. With a flair for the theatrical and an eye for clues hidden in the tiniest details, Bell astonished his students with lightning-fast deductions about his patients' lives. Though he considered his methods to be quite 'elementary', they captured the imagination of his audience - including his prized student, a young Arthur Conan Doyle, who would eventually abandon his medical career in order to create the fictional detective Sherlock Holmes.

In Sleuth-hound, award-winning historian Lindsey Fitzharris guides us through the smog-choked alleys and crowded slums of Victorian Edinburgh to recount the untold story of the man who inspired literature's most iconic sleuth. Bell's talent was so formidable that he was called upon to investigate criminal cases and, alongside Edinburgh's chief police surgeon, worked on some of the highest profile murders of the century, including Jack the Ripper. Together, the two men pioneered a new era of forensic science to crack crimes.

By scrutinizing a scratch on a desk, a trace of cigar ash, or the slightest peculiarity of a man's gait, Bell could turn the smallest clues into revelations. The result, as Sleuth-Hound grippingly shows, changed medicine, literature - and detection - forever.
