"And now you are sufficiently rested, the music is striking up for a lively quadrille, and so, if you please, we will join the dancers and dance away dull care!" said Lyon Berners, rising and offering his arm to Rosa Blondelle. She arose and took his arm. (Sybil, in her little Puritan's dress moved after them.) He led her to the head of a set that was about to be formed. "Oh! there she is!" suddenly exclaimed Rosa. "Who?" "Sybil." "Where?" "There!" And Rosa pointed to one of the doors, at which Beatrix Pendleton, in Sybil's disguise, was just entering the room. "No matter! See! she has taken another direction from this, and will not be near you, dear child; so be at rest," said Lyon Berners soothingly. "Oh! I am so glad! You don't know how I fear that woman," replied Rosa. "But you did not use to do so!" "No! not until to-night! To-night when I met her terrible eyes," said Rosa. "Come, come, dear! Cheer up," smiled Mr. Berners, encouragingly, as he took her hand and led her to the order--"Forward four!" The dance began, and Sybil heard no more; but she had heard enough to convince her, if she had not been convinced before, of her guest's treachery and her husband's enthrallment. She went and sat down quietly in a remote corner, and "bided her time." And waltz succeeded quadrille, and quadrille waltz. At the beginning of every new dance, some one would come up and ask for the honor of her hand, which she always politely refused--taking good care to speak in a low tone, and disguised voice. At length Captain Pendleton came up, and mistaking her for his sister, said: "Sulking still, Trix?" Not venturing to speak to him, lest he should discover his mistake, she shrugged her shoulders and turned away. "All right! sulk as long as you please. It hurts no one but yourself, my dear," exclaimed the Captain, sauntering off. She saw Beatrix Pendleton, in her dress, moving merrily through the quadrille, or floating around in the waltz. She heard a gentleman near her say: "I thought that lady never waltzed. I know she refused me and several others upon the plea that she never did." And she heard the other lightly answer: "Oh, well, ladies are privileged to change their minds." The waltz of which they were speaking came now to an end. Sybil saw Beatrix led to a seat near her own. She also saw her partner bow and leave her. She seized the opportunity and glided up to Beatrix, and whispered: "There will be but one more quadrille, and then supper will be served. I am going to my room. Do not dance in the next quadrille, but follow me, that we may change our dresses again. We have to be ready to unmask at supper, you know." "Very well! I will be punctual. I really have enjoyed myself in your dress. And you?" "As much as I expected to. I am satisfied."
