Roger Chillingworth is a fictional character and primary antagonist in the 1850 novel The Scarlet Letter by Nathaniel Hawthorne. He is an English scholar who moves to the New World after his wife, Hester Prynne. Chillingworth, a doctor and student of alchemy, attempts to emigrate from England to Puritan Boston. He sends his wife ahead to set up in Boston, but he is delayed by problems at sea and then held captive by Indians. When he finally arrives in Boston, he finds his wife on a scaffold, being shamed for committing adultery. Meeting Hester in jail, Chillingworth presses her to divulge the name of her partner in adultery, but she refuses. Searching without her help, he eventually discovers that her lover is the town minister, Arthur Dimmesdale. Using his position as a doctor, and under the guise of treating Dimmesdale's unexplained sickness, Chillingworth manipulates Dimmesdale into insanity and a confession of sin before the entire community before his death. Chillingworth then also dies. Throughout the book Chillingworth is referred to as "the leech", which at the time was a term for a doctor, and then dies once he no longer has a victim to harm. (en)
