By Erik Larson. The author's website describes the story as "The saga of how the lives of the inventor of wireless and of Britain’s second most famous murderer (after Jack the Ripper) intersected during one of the greatest criminal chases of all time. The inventor was Guglielmo Marconi, the young Italian genius; the killer was Hawley Harvey Crippen, who murdered his overbearing wife and fled Britain with his mistress, unaware that Scotland Yard was hot on his heels."
A nice, neat, looks-never-read paperback with very mild shelfwear.
