Riders of the Whistling Skull (1937)

The Three Mesquiteers appeared in several Republic Pictures during the 1930s, and this is considered one of their best. It's about a mysterious murder at an archaeological expedition, which leads the three prairie pals into some dangerous territory. Can they solve the murder without losing their own lives? The cast includes Robert Livingston, Ray Corrigan, Max Terhune, and Roger Williams, all trying to survive a hail of poison arrows and hot lead! (BW)
