The first 85% of this book is very good. I really enjoy historical renderings of medical cases or scientific/technological discoveries, and this recounting of the cholera epidemic in London did not dissapoint.
If the book would have ended with the conclusion of the medical mystery, I think I would have been content. But the last few chapters of this book transition from a historical retelling of the cholera epidemic to the author's opinions and predictions regarding past, present, and future outbreaks of various disease processes and epidemics. While these discussions are somewhat relevant in light of the way in which the cholera epidemic was handled, it is not an ending that I preferred. Perhaps it was just becuase I wasn't really expecting it.
Author opinions aside, I thought that this book did a very good job of following the historical events that surrounded the cholera outbreak at the Broad Street pump. Because of that, I do recommend this book to anyone who enjoys factual but well-written medical history of the 19th century.
