The corner of his mouth raised quickly—if she hadn’t been so focused on him, she might have missed it. “So certain of yourself.”

“One does not spend one’s life on the edge of ballrooms and not learn exactly what it takes to be belle of the ball, my lord.”

“If anyone can help Juliana navigate these shark-infested waters, I think it quite possibly could be you, Lady Calpurnia.” The words, laced with respect, caused a warmth to spread through Callie, which she tried, unsuccessfully, to ignore.

As the waltz came to an end and her skirts swirled back into place, she risked asking, “May I suggest you escort me to my mother?”

He immediately recognized the logic behind her words. “You think a single conversation with your mother will convince them that I am reformed?”

“It cannot hurt.” She smiled up at him as they promenaded around the edge of the ballroom. “You forget one of the most important tenets of London society.”

“Which is?”

“Wealthy, unmarried marquesses are always welcome back into the light.”

He paused, letting one finger stroke slowly across her knuckles as he spoke softly in her ear. “And if I am not sure I want to exit the darkness?”

A shiver pulsed down her spine at the words, more breath than sound. She cleared her throat delicately. “I am afraid it is too late.”

“Lord Ralston!” Her mother’s voice came, high-pitched and excited, as they approached her and Mariana, who appeared to have been watching the entire waltz, waiting for this particular moment. “How fortunate we are to have you join us this evening.”

Ralston offered a low bow. “It is I who was fortunate to have received an invitation, my lady. Lady Mariana, you are radiant. May I offer my best wishes on your coming marriage?”

Mariana smiled warmly at Ralston’s flattery, offering him a hand. “Thank you, my lord. And, may I say that I am quite eager to meet your sister? Callie has said wonderful things about her.”

“Lady Calpurnia has been a good friend to Juliana in the week since her arrival.” He looked to Callie, and added, “I am of the opinion that there is no one better to ensure my sister’s success.”

“You are absolutely correct, of course, my lord,” said Lady Allendale. “Callie’s reputation is impeccable. And, considering her age and situation, hers is the ideal tutelage for Miss Juliana.”

Callie winced inwardly at her mother’s words, which—whether intentionally or not—drew attention to her status as untouchable spinster. The real meaning of Lady Allendale’s statement couldn’t have been more obvious if she had announced that Callie had taken vows as a nun.

Lady Allendale plunged onward. “May I ask, my lord, how you and Callie came to such an agreement regarding your sister’s introduction into society?”

Callie’s gaze flew to Ralston, her heart in her throat. How was he going to avoid the truth? He replied calmly, “I confess, Lady Allendale, the agreement was entirely my idea. I was extraordinarily lucky that Lady Calpurnia happened to be in the right place at the right time, as they say. I do not know how I will repay her for such a generous offer.” Callie’s eyes widened at his reply; did she detect a teasing tone in his words? She turned her attention back to her mother, who appeared entirely pacified with the marquess’s answer, as though it were perfectly ordinary for rakes to request the company of her unmarried daughter for purposes not altogether clear.

She had to end this embarrassment. Immediately. Before her mother did something truly mortifying. As if it weren’t enough that she was dressed in a shimmering aubergine silk adorned with peacock feathers. Many peacock feathers.

“Mother, Lord Ralston has agreed to escort me to the refreshment room,” she said, avoiding Ralston’s gaze as she attempted to lie as prettily as he seemed to do. “May we fetch something for you?”

“Oh, no, thank you.” The dowager countess waved her fan in the air dismissively before placing a hand on Ralston’s arm and meeting his gaze directly. “Lord Ralston, I look forward to meeting this sister of yours very soon. Perhaps she will come to luncheon?” It was not a question.

Ralston tipped his head graciously, accepting the countess’s offer of support, saying, “I am certain Juliana would enjoy that, Lady Allendale.”

Callie’s mother nodded firmly. “Excellent.”

With that, Lady Allendale was off, poor Mariana in tow, to greet more guests. Ralston offered Callie an arm.

“I should very much like to escort you to the refreshment room, Lady Calpurnia,” he said wryly.

She took the arm. “I apologize for the untruth.”

“No need.” They walked in silence for several moments before he added, “Thank you.” He recognized how important the interaction with her family and the invitation from her mother would be in securing Juliana’s acceptance into society.

She did not immediately respond, her thoughts instead focused on the evening’s surprising turn of events. Keenly aware of the heat of Ralston’s arm under her hand, of the eyes of London’s best and brightest following their path around the ballroom, Callie couldn’t stop herself from wondering just how different this particular evening could become.

“Do not thank me too quickly, my lord,” Callie began tentatively. “After all, as you so tactfully stated, I have not yet made my request for payment.”

Ralston glanced down at her. “So I’ve noticed. I don’t suppose you’ll out with it now, so we can get it over with?”
