Ah, well, in one of the B&tB books, she mentions in passing Catherine notices a 'private detective' passing through, & that was 'the Equalizer', from the same era's shows.
And I recommend her "Ishmael" in the ST series, she invokes 2-3 versions of Dr.Who, Battlestar Galactica characters, Han Solo, Hokas, Paladin from 'Have gun, will travel', Clint Eastwood's character from 'Rawhide', 'Bonanza', & probably several others I didn't notice - in the middle of the "here come the brides" show about the founding of Seattle. Quite amusing to read.
