The difficulty in reading about centuries past is adopting the mindset of those who lived then; how can we, with our 21st century knowledge, grasp a world in which people washed their babies' diapers next to the local drinking supply and thought nothing of it? Yet, Johnson weaves such a detailed picture of London life at the time that the commonplace miscomprehensions held by both the academics and uneducated are understandable. Johnson's greatest narrative gift is capturing the extent of the devastation and its commonplace nature in 19th century London, where people lived with the constant threat of epidemic.

The last fifth of the book is given over to Johnson's theorizing about the future of city planning, trying to tie it into the work of the pioneering researchers of the cholera outbreak. This non sequitur weakens the overall book, but only slightly. The mystery is real, the medical discoveries ingenious and Johnson's research and narrative compelling.
