Summary: A dramatically rendered history of a decade in the lives of Guglielmo Marconi, the inventor and popularizer of a lot of early radio technology, and Harvey Hawley Crippen, a notorious murderer. After murdering his wife, Crippen and his lover fled and eventually boarded an ocean liner bound for Quebec. The captain of the liner recognized them, exchanged radio messages with authorities in England, and managed to get the fugitives to Quebec (where they were arrested by a Scotland Yard chief inspector who had taken a faster ship) without letting them know that their identity had been discovered. Because of Marconi's invention, millions of people on both sides of the Atlantic knew about Crippen's situation and his imminent capture days in advance.
