An exhilarating spy thriller about two women CIA agents who become intertwined around a threat to the Russia Division—one that's coming from inside the agency. Lyndsey Duncan worries her career with the CIA might be over. After lines are crossed with another intelligence agent during her most recent assignment, she is sent home to Washington on administrative leave. So when a former colleague, now Chief of the Russia Division, recruits her for an internal investigation, she jumps at the chance to prove herself once more. Lyndsey was once a top handler in the Moscow Field Station, known as the "human lie detector" and praised for recruiting some of the most senior Russian officials. But now, three Russian assets have been discovered—including one of her own—and the CIA is convinced there's a mole in the department. With years of work in question, and lives on the line, Lyndsey is thrown back into life at the agency, only this time tracing the steps of those closest to her. Meanwhile, fellow agent Theresa Warner can't avoid the spotlight. She is the infamous "Red Widow," the wife of a former director killed in the field under mysterious circumstances. With her husband's legacy shadowing her every move, Theresa is a fixture of the Russia Division, and as she and Lyndsey strike up an unusual friendship, her knowledge proves invaluable. But as Lyndsey uncovers a surprising connection to Theresa that could answer all of her questions, she exposes a terrifying web of secrets within the department, if only she is willing to unravel it...

CIA agent Lyndsey Duncan has a new asset to turn, in order to prevent the most calculated global invasion of our time. But will their blossoming friendship get in the way? After an explosive takedown of a well-placed mole within the CIA, agent Lyndsey Duncan has been tasked with keeping tabs on her newest Russian asset, deadly war criminal Dmitri Tarasenko. She arrives in London fully focused on the assignment at hand, until her MI6 counterpart, Davis Ranford, the very person responsible for ending her last mission overseas after they were caught in a whirlwind affair, personally calls for her. After a suspicious attack on a powerful Russian oligarch’s property on Billionaires’ Row in the toniest neighborhood in London, Davis needs Lyndsey to cozy up to the billionaire’s aristocratic British wife, Emily Rotenberg. Lyndsey’s job is to obtain any and all information related to Emily’s husband, Mikhail Rotenberg, and his relationship with the new Russian president, whom CIA and MI6 believe is responsible for the sudden mysterious disappearance of his predecessor, the Hard Man. Fortunately for Lyndsey, there’s little to dissuade Emily from taking in a much-needed confidante. After all, misery needs company. But before Lyndsey can cover much ground with her newfound friend, the CIA unveils a perturbing connection between Mikhail and Russia’s geopolitical past, one that could dangerously upend the world order as we know it. As the pressure to turn Emily becomes higher than ever, Lyndsey must walk a fine and ever-changing line to keep the oligarch’s fortune from falling into Russian hands and plunging the world into a new, disastrous geopolitical reality. Red London is a nuanced, race-against-the-clock story that at times feels eerily set against today’s headlines, a testament to author Alma Katsu’s 30-plus career in national security. It’s a rare spy novel written by an insider that feels as prescient as it is page-turning and utterly unforgettable.
