This military biography reveals the secret life of a closeted Austro-Hungarian intelligence officer who became a double agent in pre-WWI Europe.

On the night of May 24th, 1913, three high-ranking military officials waited outside a hotel in the center of Vienna. At around two am they heard a gunshot and knew that one of their own had just ended his life. Colonel Alfred Redl, the former deputy head of the Evidenzbüro, the Austro-Hungarian General Staff's directorate of military intelligence, and confidant of the heir to the throne. His suicide note read: 'Levity and passion have destroyed me'.

No one knew that for almost a decade, Redl had been giving military secrets to the Italians, French, and Russians. His motives for betraying the army he revered were a mystery for over a century. But after the discovery of long-lost records, the truth has been revealed.

Spy of the Century tells the tragic story of a devoted military man who was forced to hide his homosexuality, and used his wealth to please his young lover. Authors John Sadler and Silvie Fisch vividly reconstruct Redl's secret life and dramatic downfall.
