Ray Kaufman, a former homicide detective dismissed for corruption, now working as a private eye, takes photos of a rich man's much younger wife, Janet Seymour, out with her husband's business manager, Tony Howard. Janet's husband is distraught and commits suicide. Kaufman, who is still in the house, convinces Howard, who comes upon the body that they should fake a murderous intruder so Janet can collect the $500,000 insurance policy. Kaufman keeps the suicide note and the gun which Howard had picked up and, after Howard is arrested, plants them in his apartment. He offers to sell the suicide note to Janet, enabling Howard's freedom. Kojak realizes Kaufman is more capable of faking the murder scenario than Howard, and when another murder occurs, Kojak is sure of who is the criminal.
