During the celebration of Big Hat Anderson's wedding to Lily who used work in the Blue Bonnett, Anderson gives his big hat to newspaper editor Harry Tate.  When Tate walks out the saloon door wearing the hat, he's shot dead by someone shooting a rifle from a building across the way.  Dan figures out that the person was trying to kill Big Hat.  He finds out that Frank Slater was in love with Lily and from there traps the killer.  This episode was a sad day for Laramie because it marked the replacement of the interesting Jon Lormer as Dan's friend, Free Press editor Harry Tate with the decidedly uninteresting Barbara Lang playing Harry's niece Julie.  This also marked the end of the sweet but bland character of Dru Lemp.  Presumably, Julie was brought in as a new love interest for Dan Troop but she didn't last long enough for the script to move far in that direction.
