"It is to you that I owe Sherlock Holmes," wrote Arthur Conan Doyle to his former professor and mentor, Dr. Joseph Bell, in 1892. A distinguished physician and professor of medicine at Edinburgh University, and a forensic expert for the British Crown, Joseph Bell was well known for his remarkable powers of observation and deduction. In what would become true Sherlockian fashion, he had the ability to deduce facts about his patients from otherwise unremarkable details. Based on extensive research into the life of Bell and including tantalizing accounts of the connections between Bell and Conan Doyle, this biography is for anyone interested in Victorian medicine, in the history of detective fiction, and in Sherlock Holmes and Dr. Watson.
