In the novella, Appointment in Prague, one woman, a British secret agent, sets out in May 1942 to single-handedly send to hell the most evil Nazi alive—SS General Reinhard Heydrich, the head of the SD, the domestic and foreign counter-intelligence wing of the SS; second in rank only to the head of the SS himself, Reichsfuhrer SS Heinrich Himmler; and the architect of "The Final Solution" that will send millions of European Jews to their doom.When British Prime Minister Winston Churchill authorizes the SOE—the 'Special Operations Executive'— in October 1941 to assassinate Heydrich, he is unaware that the entire operation has been conceived and is being run by his Scottish goddaughter, the former Pulitzer Prize-winning Hearst photojournalist Mattie McGary. The SOE is Churchill's own creation, one he informally describes as the Ministry of Ungentlemanly Warfare and, at his suggestion, Mattie becomes one of its Deputy Directors. Mattie has a history with Heydrich dating back to 1933 and a personal score to settle. In September 1941, when the man known variously as 'The Blond Beast' and 'The Man With the Iron Heart'—that last coming from Adolf Hitler himself—is appointed Reichsprotektor of Bohemia and Moravia, the remnants left of Czechoslovakia after the Germans had dismembered it in 1939, Mattie is determined—now that he is no longer safely within Germany's borders—to have him killed. She recruits and trains several Czech partisans for the task and has them parachuted into Czechoslovakia in December 1941.
