11. The English Teacher

Complete story — includes the ending

Back in Washington, Carrie faces nearly a dozen federal charges, but Saul has her released into his custody. Searching for Saul's Russian asset, Carrie tracks down Andrei Kuznetsov, a man Saul had exfiltrated from East Berlin in 1987. Kuznetsov informs her that Saul used red leather books to communicate with him. Flashbacks reveal that Saul's asset is Anna Pomerantseva, a former English teacher for the KGB who volunteered to turn against the Kremlin after her entire class was executed because their classmate, Kuznetsov, defected. In the present, Anna is the GRU's head interpreter, joining them at a United Nations summit. Carrie discovers notes tucked in the bindings of the red leather books in Saul's collection, which correspond to various American intelligence coups. She arranges a meeting with Yevgeny to report her findings, still unable to identify the asset. Yevgeny proposes an alternative way to neutralize the asset: eliminate Saul.
