Great Scott, There's Been a Murder at the Mine
When no one has heard from his brother for a while, mining engineer, Larry Sutton (Randolph Scott) heads up to the mining location where he was last heard from to do a bit of detective work and track him down. It seems that Larry's brother's disappearance is not the only thing going on up at the mine as there has been a murder which deputy sheriff Tex Murdock (Charles 'Chic' Sale) is investigating. Larry and Tex join forces to find out what is going on where the family of mine owner Jim Ballard (George F. Marion) are waiting for him to die.
"Rocky Mountain Mystery" is not just another one of those old 1930s westerns as it also wants to be a mystery movie. As such on one hand we have the usual western style set up with Randolph Scott being the good guy stranger who shows up in town and ends up becoming friendly with a pretty young woman who happens to be the daughter of a businessman. But whilst we know something dodgy is going on with a murder we are not made aware of what is what right away and have to wait for the mystery to unfold. In truth it is quite an enjoyable little mystery, not overly subtle but still a nice variation on the usual plain sailing westerns of the era.
What this all boils down to is that due to the mystery element "Rocky Mountain Mystery" is a bit more interesting than most of these old movies yet still having the feel and style of a typical one hour western, making it easy to watch.
