Girl In The Night
The 'Ironside' Season 1 episode 'Girl In The Night' is very similar to the Season 2 episode of 'The Virginian', 'A Portrait of Marie Valonne'. And I now see why. Dean Riesner wrote that Virginian episode and provided the story for the Ironside episode.
Madlyn Rhue played the luckless Marie Valonne whose fate was similar to that of Susan Saint James' character in 'Girl In The Night'. Mark Richman (later Peter Mark Richman) played the Donnelly Rhodes part.
