Black-clad rider arrives in town. Matt knows him from Matt's own unexplained past. The man's Carl Killion, a feared gunfighter, but he is also quite personable and not at all menacing. Still he does have a reputation, and above all, why is he in Dodge. As Matt observes, Killion's not a drifter, so there must be a reason-- someone's marked for death. But who. The whole town is on edge waiting to see how his presence plays out.
Pretty good episode. Paul Langton's Killion is a charming ladies man, even if a bit over-age. Chester's thwarted attempt to spark dance-hall girl Madelyn Rhue appears to be a sub-plot; however, these tightly scripted half-hours seldom meander. Good twist ending. Frequent mentions of head-writer John Meston's home-town, Pueblo (Colorado), made me think script must be from him, but screenplay is credited to Les Crutchfield. Apparently there're advantages to being a head-writer.
