Dark Poison is set in Chicago in 1963. When a grotesque and melodramatic female seeks protection from a convict Mike helped to send up, Mike suffers paralysis. While she rifles his office, he can only watch her take a file and leave. The next morning he awakes and tries to identify what was taken. Once he pinpoints the case file he stumbles through a chain of events involving three murders (one body found in his own kitchen!), an interview with the convict at Joliet, and a reinvestigation of the diamond heist and killing--which in turn uncovers a suspicious international gem company with ties to Argentina, escaped Nazis, the Daley administration, and the CIA. The escalating case further tangles when the famous Chicago Police Commissioner, O.W. Wilson, taps Mike to flush out the Nazi mastermind for the Israeli secret police. Throughout the episode Mike struggles against attraction for Rebecca Lutz, a vulnerable blonde employed by the gem company whose sister is named in the stolen file. Rebecca becomes the client and helps Mike uncover the truth about the company. Tension builds from this triangle, which includes Molly Bennett, and parallels the building suspense in solving the murders and capturing the escaped Nazi. In a twisting climax, Mike finds himself in crossfire between the CIA, the demands of the Israeli Mossad, and the FBI. A plot to insure that the master criminal will not be taken alive unfolds to hide collusion about other Nazis who worked for West Germany against the Soviet Communists.
