You also potentially could argue that Cap’n Janeway (ST: Voyager) was Columbo’s wife and Rule 34 Kate Mulgrew.
The network execs (grrr) tried to introduce her as Mrs. Columbo around ’79. >:(
Supposedly, b/c of the uproar (fans/writers/Peter Falk) they wrote into the plotline of her (renamed)‘Kate Loves a Mystery’ series that she had gotten divorced. So b/c Columbo never divorced, to wit, she must not be the “real” Mrs. Columbo .. but, given that she was so young (24) in the series she would have been 13 yrs old when she married him, who’s to say that they didn’t divorce later when Columbo was all old and the ‘Columbo’ series was over?
