James R. Farr reveals the Giroux affair not only as a riveting murder mystery but also as an illuminating point of entry into the dynamics of power, justice, and law in seventeenth-century France. Drawing on the voluminous trial records, Farr uses Giroux's experience in the court system to trace the mechanisms of power-both the formal power vested by law in judicial officials and the informal power exerted by the nobility through patron-client relationships. He does not take a position on Giroux's guilt or innocence. Instead, he allows readers to draw their own conclusions about who did what to whom on that ill-fated evening in 1638.
