The Virginian S02E16 - Roar from the Mountain

A cougar kills a Shiloh hand and Steve Hill, experienced in hunting these animals, tracks it into the mountains where he comes upon a homestead owned by Nancy Mayhew (Joyce Bulifant) and her husband Charles (Jack Klugman). The Mayhew's have strained relations and it is learned Charles son was killed by the same cougar. Nancy blames this on Charles' cowardice and indicates a romantic interest in Steve, an interest which eventually endangers Steve's life.
