Miss Furnivall’s dramatic reaction—the first display of sincere emotion we have seen from her or Mrs. Stark—is startling. Because Miss Furnivall seems genuinely afraid of the child, readers begin to suspect that she might know more than she’s saying about the cause of the supernatural happenings. This increases the suspense of the scene and greatly heightens the pervading sense of danger, and gives credibility to Rosamond’s version of events. Readers will likely begin to suspect that the supernatural events have something to do with the household’s history based on her outburst.
