Geronimo1967
A visiting lecturer (Lee Kohlmar) is speaking in a pitch-black planetarium when a gunshot causes mayhem and the body of "Dr Stone" is found slumped in a seat. Local cop Russell Hopton and journalist Lola Lane vie to discover the culprit. Unfortunately the print I saw very recently was poor, the lighting all over the place (though the sound was a damn sight better than many virtually inaudible dramas produced today!) but that didn't detract from this enthralling little murder mystery that keeps you guessing - partly because there appear to be so many suspects - right to the end of the 70 minutes.
