Death of Sherlock Holmes [PDF ebook] 

The previous diaries of Arthur Conan Doyle tell of the shadowy real life Sherlock Holmes, a medical school dropout. While in the laboratory of Dr. Joseph Bell, a brilliant Edinburgh surgeon, Holmes learned anatomy, surgery, observation and deduction. These skills and his ability to solve crimes led to his recruitment by the British secret service. In this the last of three diaries, Doyle recounts a series of murders and the pursuit of a sinister Russian assassin from Edinburgh to the Yosemite Valley in California. When the case, involving a California millionaire and Chinese tongs becomes desperate, the British secret service sent Sherlock Holmes. The case ended in his death but the great detective lives on in the novels by Arthur Conan Doyle.
