Death in the Air by Kate Winkler Dawson

Death in the Air: The True Story of a Serial Killer, the Great London Smog, and the Strangling of a City - Kate Winkler Dawson

In December of 1952, a brutal winter and inferior heating coal collided with London's infamous fogs to produce a killer smog so lethal, it took the lives of thousands and literally strangled a city. Meanwhile, serial killer John Reginald Christie was adding to the body count, hiding his victims about his home and property.
Kate Winkler Dawson does a masterful job of weaving the stories of these two different harbingers of death on the streets of London, and displaying how each impacted that city in near equal measure, and left their filthy fingerprints on the pages of it's history.
Extensively researched and beautifully written, this book proves that history can be as engaging as any fictional work.

Highly recommended.
