Beauvallet by Georgette Heyer

Doña Dominica thought it imperative that Beauvallet's impudence should be suitably punished, and took it upon herself to perform this pious office. Master Dangerfield was a tool ready to her hand; she sought him out, cast a thrall about that susceptible lad, and flirted with him, somewhat to his embarrassment. She brought her long eyelashes into play, the minx, was all honey to him, and flattered the vanity of the youthful male. She used a distant courtesy towards Beauvallet, listened when he spoke to her, folded meek hands in her lap, and turned back to Master Dangerfield at the first chance. Beauvallet had stately curtseys and cool impersonalities from her; she let it be clearly seen that Dangerfield could have if he chose a hand to kiss, her smiles, and her chatter. Master Dangerfield was duly grateful, but showed a lamentable tendency to set her high upon a pedestal. At another time this might have pleased her, but she had now no mind to play the goddess. She was at pains to show Master Dangerfield that he might dare to venture a little further.

But all this strategy failed of its object. Doña Dominica, out of the tail of her eye, saw with indignation the frank amusement of Sir Nicholas. Beauvallet stood back and watched the play with a laughing, an appreciative eye. The lady redoubled her efforts.
