孟买的杀手 The Stranglers Of Bombay (1959)

A murderous religious cult is way-laying travellers and stealing goods in nineteenth century India. As the disappearances mount and trade becomes difficult, the British East India Company is forced to act. But they give the job to an upper-class officer completely out-of-touch with the country rather than the obvious candidate who has been in India for years and well understands the people and culture.
