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.”
