This book was great and really interesting! It talks about a number of health and contamination problems in the 1800s in London. Dead bodies, cess pools, ash, smoke, disease, bathing, mud, poop, clean water...It was really interesting. My complaint was that is was a little dry and hard to get through at some points. Still, well researched and has opened my eyes to a whole new world behind my historical romances I so love to read.
