The Toast of Death(1915)

Ballerina Poppea is adored by all the men of Calcutta, especially British soldier Captain Drake and Indian PrinceYar Khan. Because of his title and wealth, Poppea decides to marry the prince, while keeping Drake as a lover. But the prince eventually discovers what she's up to and goes out of his way to catch the adulterers together. He takes two glasses of wine, pours arsenic into one, and tells Poppea to choose which glass each man will drink. She innocently picks the poisoned glass for Drake and he dies horribly. The prince disposes of the body and drives Poppea out into the desert.
