Pierre, or Peter, is one of Mrs. Stafford-Smyth's grandsons. He comes to visit his grandmother in order to try to earn an ideal spot in her will. At first, Pierre suspects that Belinda may be intending to try to befriend his grandmother in order to try to take advantage of her, but soon realizes she is too innocent for that. Pierre is at first upset that his grandmother wants him to accompany Belinda around town even though she is a member of the staff, but soon begins to enjoy his time with her. Pierre leaves Boston to return to France with little warning because he feels that he is developing feelings for Belinda but realizes that their two worlds will not mesh. When Belinda and Mrs. Stafford-Smyth visit Pierre in France, Pierre has married Anne-Marie.
