No, Peter Falk, aka Lieutenant Columbo, never appeared on the series “Mrs. Columbo” (NBC, 1979).

It was never completely clear that the title character, Kate Columbo (Kate Mulgrew) was even married to the rumpled policeman.

Midway through the short-lived series, the character was renamed Kate Callahan and the title became “Kate Loves a Mystery.”
