Bonanza - Season 1 - Eps 31: Dark Star
Joe falls in love with Tirza, an undeniably strange gypsy girl who says she is cursed and never does seem to "snap out of it". The first episode of the series with a supernatural flavor, directed appropriately enough, by Lewis Allen, who made the classic ghost film "The Uninvited".
