The queen at first resented the open and undisguised infidelities of the king, and publicly manifested her sense of them on one occasion by quitting the theatre when Miss Davis made her appearance on the stage; but, finding it impossible to reclaim him from his vicious propensities, she abandoned all hopes of restricting his libertinism, or even of keeping him within the bounds of conventional decency. The Countess of Castlemaine (afterward created Duchess of Cleveland) was of a more jealous temperament than the queen, and took a more characteristic revenge on Charles for his frailties. She took another lover, and went to reside at his house, very much to the comfort of her royal patron, who had a kingly dislike of trouble. After quarreling with Lord Buckhurst, Nell Gwynne returned to the stage, but had not long resumed her profession when it was rumored that she had made a conquest of the king. These reports were apparently contradicted by her continued appearance at the theatre, and the progress she made in her art, which could only be the result of careful study. A tragedy by Dryden was advertised, the principal character to be performed by Nell; but, before the night of its first representation arrived, it was found necessary to postpone the performance, owing to Nell's not being in a condition to appear. From this time her connection with Charles no longer remained a secret. Nell, like her predecessors, was not long suffered to maintain uncontested her supremacy over the king's affections. When the Duchesse d'Orleans, the sister of Charles, paid a visit to the English court in 1670, she had in her train a handsome maid, who was admired for her simple and childish style of beauty. Whether instigated by the courtiers who accompanied her mistress, whose visit was a political one, or prompted by her own sagacity, she made her acquiescence in the king's desires conditional upon his executing the shameful treaty which gave France such important advantages, and rendered Charles a mere tributary to the French king. This girl, Louise de Querouaille, became the rival of Nell Gwynne, and had a child by Charles, who was created Duke of Richmond.
