An Agent In Place by Robert Littell

A tense, character-driven spy novel that follows a veteran intelligence officer who depends on a long-term mole inside the Russian security apparatus; as the world moves from the Cold War into the chaotic post-Soviet era, loyalties and identities blur and long-buried betrayals surface. The narrative interweaves operational tradecraft with intimate human drama, exploring the moral costs of espionage and the ways personal sacrifice and political intrigue reshape lives and nations.
