Stewart was never better on the air than in this drama of Britt Ponset, frontier drifter created by Frank Burt. The epigraph set it up nicely: “The man in the saddle is angular and long-legged: his skin is sun dyed brown. The gun in his holster is gray steel and rainbow mother-of-pearl. People call them both The Six Shooter.” Ponset was a wanderer, an easy-going gentleman and — when he had to be — a gunfighter.
