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...
