The Legend of Lylah Clare (1963, DuPont Show of the Week)

Well, you could have knocked me over with a feather. Warner Archive finally released the 1968 feature film adaptation (directed by Robert Aldrich and starring Kim Novak) on DVD after many decades of not being available in any home video format, but this, the original TV version (directed by Franklin Schaffner and starring Tuesday Weld) was still nowhere to be found apart from a single clip and some stills.

Not anymore! Here's the whole thing! Incidentally, this was way better reviewed than the Robert Aldrich adaptation (which I kind of have a complicated relationship with, but which I actually do like).
