A peaceful moonlight drive in the English countryside is interrupted when Simon Templar and Patricia Holm listen to a disturbing radio broadcast from France by a would-be dictator who plans to make France the latest in a growing number of European dictatorships under a ruling party called the Sons of France. This broadcast disturbs Patricia, and Templar makes a dire prediction that the future of Europe will be one of invasions and concentration camps. The two adventurers are interrupted in their worries when they spot a house on fire in the distance. Rushing to help, Templar enters the burning building but is unable to rescue a man trapped inside. Later, he and Patricia learn that one of the occupants of the house is a known war profiteer who is expected to make millions off both sides should a new European war erupt.  Considering this book was first published in 1938, the storyline is an uncanny prediction of what was to come.
