Very sad. For me that episode had the creepiest ending when Nicholas Frame 'loses it.' Gives me the shudders hearing him reciting Shakespeare and laughing in the background after getting found out.
Along with P---- Galore in GOLDFINGER (I'm guessing the full name would be edited if I used it), she was great as Hera in JASON AND THE ARGONAUTS.
And many other roles, of course.
She was excellent in "Columbo" and in those other roles as well, even if a bit cartoonish but of course that was part of what was called for. Sadly we've been hearing of deaths in the family of "Columbo" actors for some time, but in this case, the fact that Honor was 94 somehow really brings home the historical context of Colubmo's original era. RIP.
