The Conspirators is a novel written by Alexandre Dumas. It was adapted into an opera Le chevalier d'Harmental by Paul Ferrier. The novel is set around 1718, and its subject is a conspiracy against the regency rule of Philippe d'Orléans, who led France during the infancy of Louis XV. A section of the novel involving a street named "rue du Temps-Perdu" (street of wasted time) may have inspired the title of Marcel Proust's À la recherche du temps perdu.
