Catherine Jinks lives sometimes in Australia, sometimes in Canada, but all her life she has been passionately studying the Middle Ages, the era of the Crusades and the great knightly orders that strived for power in Europe and Asia. She also writes her books about this era, which enjoy constant success in the English-speaking world. Jinx's new novel takes us to 14th-century France, during the years when the Catholic Church wages a war of annihilation against the Albigensian heretics. The movement of the Albigenses or Cathars, who rejected the church hierarchy and the papacy, swept, starting from the 12th century, all of southern France, captivating both the nobility and the common people. The case of the Cathar heresy is investigated by an inquisitorial court composed of Dominican monks, but the investigation is interrupted by the brutal murder of the senior inquisitor, Father Augustine. The search for the killer brings his subordinate, brother Bernard, back to the complicated events of fifty years ago. On the way to the solution, Bernard not only learns the terrible secret of Father Augustine and discovers a traitor in his inner circle, but also meets his love.
