Mom P.I. - Season 1

Mom P.I. is a 1990-92 Canadian television comedy-drama series starring Rosemary Dunsmore, Stuart Margolin, Emily Perkins, and Shane Meier. Dunsmore plays eternal optimist Sally Sullivan, a recently widowed mother of two supporting her family as a waitress in a working-class diner, who talks her way into a job as assistant to grumpy, cynical private eye Bernie Fox, played by The Rockford Files' Margolin. Head writer for the show was Chris Haddock, who later created the much grittier Da Vinci's Inquest and Intelligence, also for the CBC.
