'This historical play is based on the incident of the selling of England to France through the weakness of Charles the Second, who, infatuated with Louisa de Queroualle, the Maid of Honour to Henrietta, the Duchess of Orleans, who brought the Treaty to England, signs the Treaty, through which Louis the Fourteenth of France promised to support Charles against his Parliament. Fortunately, this deed was never called into effect, and thus was never made public during the lifetime of the King, a copy of the Infamous bargain being discovered long after the death of Charles, where it had been filed in the archives in Paris.'
