The Conspirators

The Conspirators (original French title: Le chevalier d'Harmental) is a novel written by Alexandre Dumas and Auguste Maquet, published in 1843. Dumas reworked a preliminary version by Maquet; this was the beginning of their collaboration which was to produce eighteen novels and many plays. The dramatisation of the novel - in five acts, a prologue and ten tableaux - was first performed on 16 July 1849 at the Th tre-Historique in Paris. It was adapted into an opera Le chevalier d'Harmental by Andr Messager with a libretto by Paul Ferrier, which was first performed on 5 May 1896.

The novel is set in 1718, and its subject is a conspiracy against the regency of Philippe d'Orl ans, who led France during the infancy of Louis XV. Dumas and Maquet's later novel Une fille du r gent features some of the same characters.
