Mathnet is a segment on the children's television show Square One Television, of which five seasons were produced. This parody of Dragnet featured detectives at the Los Angeles Police Department who solved mysteries using their mathematical skills. There were two main characters: detectives Kate Monday and George Frankly. Mary Watson also had a regular role as the duo's technical analyst, Debbie Williams. The third season had the show's setting moved to New York City. Beginning in the fourth season, Kate Monday was replaced by Pat Tuesday. James Earl Jones played a recurring role as Chief Thad Green. He also briefly appears in season 4 and indicates he knows Pat Tuesday. When the duo was transferred to New York, Captain Joe Greco became their new boss and undercover NYPD officer Benny Pill became their semi-regular backup support.
