Larson’s true-crime historical non-fiction 2006 book is excellent.

I loved learning about technology of the day. This time the early 1900s.

Guglielmo Marconi, the young Italian entrepreneur. Often credited as the inventor of radio. He shared the 1909 Nobel Prize in Physics. He had no training in physics. And was a jerk.

Hawley Harvey Crippen, who murdered his overbearing wife and fled Britain with his mistress, unaware that Scotland Yard was hot on his heels. Nice guy — aside from the murder

The two men never met, yet their interacting stories make up this tale.

The climax occurs during a trans-Atlantic chase which, thanks to the miracle of Marconi’s invention, was followed by millions of people around the world—with Crippen and his mistress completely unaware.
