Der Chinese(1979)

Constable Studer of the Bern cantonal police is stubborn and gnarled. Because of his nature, he has few friends. He has this in common with the murder victim: James Farny was known by everyone as "The Chinese". The man had traveled the world and now he has been found shot dead in the village cemetery: was it murder or did he kill himself? He had the gun in his hand. Studer doesn't believe it was suicide...
