Plot

This story concerns Dan Coulee, a supposed cattleman, his only daughter, Mary, and her sweetheart, Bob Weston. Bob has been elected sheriff. Bob is elated at his good luck and comes to tell his sweetheart. Her father is there at the time, but doesn't seem to share the enthusiasm engendered, yet he likes Bob amazingly and has no objection to Bob marrying his daughter. But if Mary was overjoyed at the good fortune of Bob, she was also harassed with fear for his safety, as Bob's first mission was to capture a noted outlaw known as "Black Robert." This man had been terrorizing the vicinity for some time, doing his work single-handed, and his deeds were much talked of. Dan Coulee could have wished that anyone else than Bob had gotten the sheriff's job, perhaps because of the desperate character of the bandit. It so happens that Bob's posse are compelled to return, and Bob decides to follow the trail of the outlaw alone, for which undertaking his bravery and heroism are rewarded with success. His daring riding and unsurpassed courage has done for him what others have failed in; he has captured the famous Black Robert! He is downhearted and miserable, for his prisoner is none other than the father of his own sweetheart, Dan Coulee, the supposed cattleman. No wonder Dan hated to see his intended son-in-law become sheriff. Should he arrest or release Dan? His sense of duty won out. It is needless to say that Mary was broken-hearted. But she saw that while her father was lacking in goodness, she had found in her sweetheart one who could rise sublimely above all self-considerations and dare to do right.
