The Physician's Dark Bargain — The Scarlet Letter

After the scaffold, Hester and Pearl suffer a dangerous collapse in the prison, the child convulsing as if she has absorbed her mother's agony. The jailer sends for Roger Chillingworth, the same stranger from the marketplace, who treats them with unsettling calm.

He eases Pearl with medicine, then offers Hester a draught that may quiet her nerves but cannot give a clean conscience. When she suspects poison, he answers that letting her live with the letter is vengeance enough.

Their interview becomes a reckoning. Chillingworth admits he married a young woman without love and sent her ahead to Boston, accepting shared guilt for the mismatch, yet he demands the name of Pearl's father. Hester refuses absolutely. He then reveals his plan: he will read guilt in the lover's body though no mark shows on his clothes, and he will not expose him to law if he can pursue him privately.

Most binding of all, he makes Hester swear never to tell the colony that Roger Chillingworth is her husband. She takes the oath, knowing she has traded one public shame for a secret that will shadow Pearl, Dimmesdale, and the whole settlement.
