The Cold War is over. Its habits are not.

When a dead broker in Berlin leaves behind a fragment pointing east, CIA deputy station chief Phil Swain and Russian consultant Tatiyana Druyanova follow the line from Berlin to St. Petersburg to Moscow. What begins as a relic of Soviet procurement opens into a protected corruption structure running through transport, archives, intelligence channels, and men who survived the collapse of the state by changing letterhead rather than loyalties.

As senior Russian officer Bersanov tries to move the truth outside General Orlov’s control, Swain, Tatiyana, and Moscow station chief Richard Kessler are forced to decide whether intelligence is enough—or whether the line must be carried state to state at a level that changes succession inside the Russian security world itself.

Stopover in Leningrad is a novel of espionage, institutional memory, old loyalties, and the cost of understanding a system just well enough to alter it.
