Just as Philip was within his rights to feel embarrassed and confused in the preceding scene, du Maurier makes it clear that Rachel has a right to her humiliation as well. Rachel is upset because Philip has made it seem as though Rachel has no respect for Ambrose. Even more than being publicly embarrassed, Rachel seems to feel genuinely guilty about having slept with Philip so soon after losing Ambrose. Philip’s accusation that Rachel was “not ashamed at midnight” is all the more cruel for this reason, since it throws Rachel’s own sexual desire back in her face, as if to humiliate her even further. Rachel, too, is cruel in suggesting that the only reason she slept with Philip was to thank him for the jewels. This fraught conversation captures the complexity of sex and the vital need for communication if two people hope to ever understand the slightest thing about one another.
