S3·E27 Santa Claus Wears a Gun

A elderly sharpshooter, Snowy Kringle, arrives in town for show where he will demonstrate his skill with a flintlock rifle and cap-and-ball pistol. The man who is charged with delivering the Army payroll warns the Deputy Sheriff that the old sharpshooter is really a crook and is probably after the payroll. When the express office is robbed, all the evidence points to the old man, but Annie suspects he's been framed for the crime.
