Peter Marlow goes undercover to infiltrate the KGBThe Soviet intelligence agency’s worst nightmare has come true: Besides the five directorates that oversee its operations, there lurks a sixth—a shadow directorate that may be plotting a coup against the Communist Party. Disruption of the KGB might spell trouble for Moscow, but for the British Intelligence, chaos in the Soviet Union means a chance to infiltrate. To make the most of the opportunity, Her Majesty’s intelligence service turns to Peter Marlow, a disgraced former spy who has spent the last four years in jail. He is given his freedom in exchange for his espionage service. Peter assumes the mantle of George Graham, a KGB agent with more secrets than he’s prepared to handle.  The Sixth Directorate is the second book in the Peter Marlow Mystery series, which also includes The Private Sector and The Valley of the Fox.
