Mercy Brown, the Exeter vampire

In 1892 the Brown family of Exeter, Rhode Island, was losing one member after another to tuberculosis. Neighbours convinced the father that one of the dead was feeding on the living, and in March the bodies were exhumed. Two had decomposed; nineteen-year-old Mercy, who had spent the winter in a cold crypt, had not. Her heart was burned, the ashes mixed with water and given to her dying brother to drink. He died two months later. The case is the last and best-documented episode of the New England vampire panic — an attempt to explain an epidemic for which people had no other language.
