Mad Barbara by Warwick Deeping

Barbara Purcell stood alone by the window, her eyes fixed upon the torches that were spitting and flaring in the rain. The salon had been emptied of its wits and gallants, as though the men had been whirled away into the darkness by the very energy of my Lord Pembroke's wrath. The women were left alone with the cynical old aristocrat who dabbled in science, and who had not moved from his chair during the brawl. Hortense, who had dreaded bloodshed in her house and the scandal that might follow, was watching from another window, with the three girls and the widow gathered round her. My Lady Purcell appeared to be the most vexed and troubled of them all. She moved restlessly about the room; sat down in a chair beside the cynic; spoke a few words to him, and seemed repelled by the flippancy of his retort; rose again; walked to and fro for a minute, and then, as though driven thither by some spasm of suspense, joined Hortense and the rest at the window.

The Mancini heard my lady's deep breathing, and, turning to make room for her, was startled by the scared expression of her face. But, being discreet, she ignored her guest's uneasiness.
