The Double Agent series is Alex Gerlis’s most recent work, with Every Spy a Traitor published in 2024 and The Second Traitor following in 2025. The series focuses on the theme of double agency and betrayal within the intelligence world.
Building on the espionage foundation of his earlier series, Gerlis uses the Double Agent books to explore what happens when spies turn against their own side. The two-book series adds another layer to his body of work on wartime and Cold War-era intelligence.
