Aired Sunday nights for two seasons from December 1973 to December 1974.
This one hour crime series could be considered a precursor to CSI: Crime Scene Investigation. The Collaborators were forensic scientists who worked with police to solve crimes.
The drama was created by Richard Gilbert and featured Michael Kane, Paul Harding and Toby Tarnow in the lead roles. Each story took viewers from the crime scene to the police station to the lab, offering insights into the investigative process. Harding left the show after the first season and Kane left the show after two episodes of the second season, due to health reasons. As a result, the show's ratings declined and The Collaborators was not renewed for a third year.
Nevertheless, it did have a strong cast, creative writers and proven directors.
