Lucy Pym, a former French teacher who has unexpectedly achieved fame as an author of popular psychology, arrives at a prestigious women's physical training college to give a lecture. What she expects to be a single afternoon engagement turns into an extended stay when the principal, an old school friend, invites her to remain for the final weeks of term. Lucy finds herself immersed in the intense, insular world of Leys Physical Training College, where young women undergo rigorous preparation for careers as gymnastics instructors. The students live, train, and compete together in an atmosphere of disciplined camaraderie, but as Lucy observes them more closely, she begins to detect currents of ambition, jealousy, and suppressed rivalry beneath the surface of their seemingly wholesome routines.
Tey crafts a deceptively quiet mystery that unfolds not through dramatic crimes but through keen psychological observation. The confined setting—a single institution in the English countryside during the final stretch of an academic year—becomes a pressure cooker where small grievances and long-held resentments gain weight. Lucy's position as an amateur psychologist gives her confidence in her ability to read character and motivation, yet the novel subtly questions whether anyone can truly know another person's heart. The physical training college, with its emphasis on discipline, fairness, and moral uprightness, becomes an ironic backdrop for examining how justice and morality can diverge.
This is crime fiction that operates on a slow burn, more concerned with moral ambiguity than neat solutions. Tey rewards patient readers who appreciate psychological complexity over action, and those who find satisfaction in watching assumptions crumble. The novel poses uncomfortable questions about the nature of justice, the reliability of our judgments, and the distance between what we think we know and what we're willing to act upon.
