Rachel’s eyes will become a recurring symbol throughout the novel. Here, Ambrose depicts Rachel as a sinister, stifling force, and her watchful eyes represent that power. As Philip gets to know Rachel over the course of the novel, he will rely heavily on her eyes to gauge her true feelings, reading in them by turns laughter, love, and cold impenetrability. By amassing these many different depictions of Rachel’s eyes—and by never entering Rachel’s point of view in the narration—du Maurier pushes back against the platitude that “eyes are the window to the soul,” suggesting instead that people often superimpose their own feelings or desires onto others.
