Robert Chillingworth is actually a false name for Hester`s husband. The two were married in England. Because Chillingworth had work to do in Amsterdam, Hester left for New England first and he followed, being delayed for several reasons. When he sees Hester with Pearl on the scaffold, he realizes that she has committed adultery. He visits Hester to discover the identity of her lover but at first Hester declines to reveal it and then identifies Dimmesdale as the lover. Chillingworth spends time with Dimmesdale to confirm his identity as Hester`s lover and get revenge.
