On discovering that Rosalie is vulnerable, Mary blackmails her into corroborating everything she says. When Karen and Martha realize why all their pupils were pulled out of their school in a single night, they go to Mrs. Tilford's residence to confront her. Amelia tells Mary to repeat her story. When Karen points out an inconsistency, Mary pretends to have been covering for Rosalie, who reluctantly corroborates Mary's story for fear of being exposed herself. Resolving to take Amelia to court, Martha and Karen leave.
