In the 21st entry in the series, Ray Corrigan returns to the Range Busters, but John “Dusty” King has departed, along with David Sharpe; Dennis Moore joins as well, and Max “Alibi” Terhune, with Elmer, remains (the only member of the trio to star in all 24 movies). This time around, the boys are looking into mail robberies and must also deal with supposed vigilantes, too. Charles King turns in another performance as a crook, this time saloon keeper “Faro” Wilson, who begrudges losing money in a card game. Supporting player Fred Toones makes some valuable contributions to the investigation as the boys’ cook. This is weaker than some of the earlier movies in the series, but entertaining for fans.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 183 for 2021.
