Let’s just start with the bait-and-switch, and get that out of the way: Dr. Arthur Conan Doyle had NOTHING to do with Dr. Robert Koch’s research into the causes and potential cures for tuberculosis. They had one point of commonality, in November of 1890, when Doyle traveled from Southsea, England to Berlin to try to attend Koch’s demonstration of a “cure” for consumption. As it turned out, the two men never even met – Dr. Doyle was turned away from Dr. Koch’s house because the doctor was too busy to meet with a stranger from England, and Doyle was not even able to get a ticket into the presentation. Doyle went back home and wrote up an account of Koch’s presumed discovery based on information passed on to him by one of the attendees who took pity on Doyle and passed on his notes.
The book turns on that point in time – everything before that date focuses on Dr. Koch’s history and research leading up to that moment, and after that date focuses on Dr. Doyle’s history, leading through his career as a doctor to his career as a writer and his creation of Sherlock Holmes. If you’re reading this book (as I did) hoping for some heretofore unknown collaboration between Doyle and Koch, you will be disappointed. However, if you read the book for insights into the turning point of medicine when the much-debated germ theory of disease was finally proven as scientific fact, you will be amply rewarded. The explanations of the differing methods and results of Lister, Pasteur, Koch, and other doctors, scientists, and microbiologists are well-written and understandable to non-scientists. It’s difficult for modern readers, who are well versed in the realities of germs as the cause for disease and illness, to look back at a time when even the most learned of scientists considered germ-theory as a crackpot idea. But this book explains clearly why it was so difficult to provide proof of that theory, until technology developed enough to provide a way to see the germs and track their growth, both in the lab and in human beings. In that respect, this book is a fascinating look at a specific point in medical history. As far as Doyle and Sherlock Holmes are concerned, it’s less fascinating, and more of a re-hash of already common knowledge.
