1x19 - The Deputy

While defending the Spencer ranch against rustlers, Deputy McCord shoots and kills ranch-owner Aaron Spencer. Though the shooting seems justified, McCord feels guilty, especially when breaking the news to young Mrs. Spencer. At first she is angry and bitter but later softens and seems to be falling in love with McCord, much to his discomfort. Red Dawson and his rustlers now break into the Spencer home one night, demanding money. (It seems Aaron Spencer, unknown to his wife, was the rustler's secret partner.) McCord arrives in time to arrest the rustlers and Mrs. Spencer decides to join relatives in Canada.
