In Gunsmoke #399, "Hard Lesson," a desperate young man named Joe Belvin faces an impossible choice when his outlaw brother Pete comes home mortally wounded from a bank robbery. Pete has returned seeking their mother's healing touch, only to learn she died a year ago. With Pete bleeding badly and refusing a doctor for fear of the law, Joe rides into Dodge City to strike a deal with Marshal Matt Dillon. The naive farm boy believes that returning the stolen money will square everything with the law and save his brother, but he receives a hard lesson when Matt tells him Pete would still have to stand trial regardless.

Frustrated and angry that the law won't help his dying brother, Joe returns home and hides Pete before Doc Adams arrives. When Matt and Chester ride out to investigate, they find blood but no patient, as Joe stubbornly refuses any assistance that might bring the law down on Pete. The young man is determined to protect his brother at any cost, even as Pete grows weaker and mentions his outlaw partners, Lo and Raleigh, who aren't far away. Joe must now decide whether his misguided loyalty will lead to more tragedy or whether he'll accept the hard truth about justice and the law.
