You are all dead men

Disturbance Patrol's hunt for the Viper is hampered by Kourosh's arrest. But once they get a tapped phone on him, it leads them to Edmond, who proves a capable opponent. Louise's nocturnal investigation into the jet set's coke consumption leads her to Edmond's little brother. Smiley's investigation is uncovered and shut down, but when Niller kills himself in front of him, he refuses to let go.
