The Spy Masters series by Alex Gerlis is a collection of four standalone spy novels set during World War II. Each book focuses on a different intelligence operation in a different European city, from Switzerland to Austria to Germany.
The Best of Our Spies (2012) launched the series with a story tied to D-Day preparations, and subsequent entries explored espionage in Switzerland, Vienna, and Berlin. While each book tells its own story, the series shares a consistent focus on the moral compromises and personal risks that wartime spying demands.
