Betrayal, survival, and the fate of nations hang in the balance as a Russian orphan turned double agent navigates the treacherous world of espionage during World War II.

In The Double Agent, a sequel to the acclaimed A Single Spy, William Christie weaves a riveting tale of deception and danger. Alexsi Smirnoff, a Russian orphan trained by the Russian Secret Service and inserted into Nazi Germany, finds himself trapped between two brutal dictatorships. Desperate to protect himself, Alexsi betrays both sides in a daring ploy that succeeds-and fails.

With his false identities burned and his life at risk, Alexsi is caught by the British and recruited by the SIS. Sent to Italy under a new identity, he finds himself at the nexus of competing forces: the Vatican, the Italian resistance, and the ruthless German Army determined to maintain control of Northern Italy.

As the war reaches a critical juncture, Alexsi must navigate a web of deceit, forge alliances, and finally choose sides in a battle for survival. Christie's fast-paced, compelling novel of espionage takes readers on a suspenseful journey through one of the most momentous and dangerous periods in history.
