Boileau-Narcejac’s works included in this book are extraordinarily multi-layered and information-dense in how they reveal the authors’ creative credo. The mystical exoticism of “The Enchanted Fear” (Zaklyatie); photographic accuracy in depicting the morals of the Parisian bohemia in the novel “Hearts in Discord” (S serdecem ne ladou); and rich philosophical reflections on good and evil against the backdrop of echoes from the long-finished Second World War—these elements shape the fabric of “The Tragedy of Errors.” What unites all these works is the invariable humanity and anxiety for a human fate in a merciless real world, always inherent to P. Boileau and T. Narcejac.
