I enjoy watching old reruns of Columbo and just thought I'd show some female guest stars who were in both Columbo and Bonanza.
Suzanne Pleshette, one of my faves back in the day, guest starred in "A Place to Hide'. Jodie Foster played her daughter.
Pleshette played a divorcee who witnessed a murder in Columbo's "Dead Weight." This was a year (1971) before she starred in The Bob Newhart Show and her stint on Bonanza.
