Mrs. Rushton devoted only two or three seconds of close consideration to the question before nodding once, decisively. “I will give you a commission provided I do not have to pay you so much as a single penny if you are unsuccessful in locating the bracelet.”

“That is understood,” Lavinia said. “Now, then, as we have established a business arrangement, I would like to ask you some questions, if you don’t mind.”

“What sort of questions?”

“You mentioned that you suffer from delicate nerves and that you are prone to bouts of female hysteria.”

“Yes.”

“When I called yesterday afternoon, your housekeeper remarked that you take regular treatments from a mesmerist.”

“Indeed,” Mrs. Rushton said. A glow of enthusiasm blazed in her eyes. “Dr. G. A. Darfield. He is excellent, I must say.”

Lavinia recalled one of the advertisements she had studied. “I saw a notice of his services in a newspaper. He claims to be especially skilled at alleviating the symptoms associated with female hysteria in married women and widows.”

“I can assure you that I have consulted with many doctors and various types of medical practitioners over the years, but I have never had such amazing results as those I have obtained from Dr. Darfield’s therapies. I cannot begin to describe the marvelous sense of relief and well-being that descends upon me following a session with him.”

“May I ask if you ever consulted Dr. Howard Hudson?” Lavinia asked, holding her breath.

“Hudson?” Mrs. Rushton’s brows snapped together above her long nose. “Hudson? No. I have never even heard of him. Does he treat cases such as mine?”

Bloody hell, Lavinia thought. She had been convinced that she would uncover a link between Mrs. Rushton and Celeste Hudson.

“Dr. Hudson’s wife was the lady who was murdered,” Tobias said. “We have reason to believe that she may have been involved with the theft of the bracelet.”

“Dear heaven.” Mrs. Rushton touched her bosom again. “This entire affair is becoming odder at every turn.” She gave Tobias a melting glance. “I am relieved to know that a gentleman of your obviously vigorous physique is investigating, Mr. March.”

Lavinia cleared her throat. “I am also investigating the case. I assure you, I am every bit as vigorous as Mr. March.”

Lavinia went straight to the sherry cabinet the moment she walked into her study. She poured two glasses, handed one to Tobias, and then threw herself down into her favorite chair.

She propped her ankles on the hassock and watched Tobias crouch carefully to light the fire. He seemed to move without obvious discomfort today, she thought, no doubt because the sun was out.

“Damnation,” she said. “I was so certain that we would uncover a connection between Mrs. Rushton and Celeste Hudson.”

“That would have been much too convenient.” Tobias gripped the mantel and used it to haul himself to his feet. He took a long swallow of sherry. “This case does not lend itself to simple answers. But look on the bright side. We have got another client.”

“Thanks to me.”

“Indeed.” He raised his glass in a mocking salute. “You did very well.”

“Mmm.” She sipped sherry. “Unfortunately, I am forced to conclude that, although approaching Mrs. Rushton was my idea, it was the sight of your obviously vigorous physique that secured us the commission.”

“I am delighted to know that I was able to contribute in some small way.”

“Not small,” she mumbled into the glass.

“I beg your pardon?”

“I believe Mrs. Rushton was persuaded to employ us because she has concluded that the portion of your obviously vigorous physique that interests her is most assuredly not small.”

He grinned. “You’re jealous.”

“The woman is a female version of a lecherous rake. She reminds me of my former employer, Mrs. Underwood.”

“The lady’s sexual proclivities aside, the fact that she hired us to find the Medusa would seem to settle the question of whether or not she might have been involved in the theft.”

“So it would appear.”

“Come now, Lavinia, you saw her face when she returned from checking to see if the bracelet was missing. It was obvious that until that moment she had no notion that it was gone.”

“I suppose it’s possible that she is a very fine actress.” Lavinia leaned her head back against the cushion. “But I’m inclined to agree with you. My intuition tells me that she was not pretending her response. She truly was stunned by the loss of the bracelet.”

“Yes.” Tobias wandered over to the window and stood looking out into the small garden. “Now all we have to do is find the bloody Medusa and the killer and we can collect fees from a number of different clients. I must admit, I was not at all enthused about this case at the start, but it is beginning to show some potential for profit at last.”

“What do you suggest we do next?”

“Mrs. Rushton believes that she has the only key to the safe in Banks’s dressing room, but she did not take up residence in the household until a few months ago. It’s quite possible that the servants know more than she realizes. Some of them would have had access to those keys for years.”

“Do you think it would be a good idea to interview them?”

“It certainly cannot hurt. But the Banks household staff is large. It will take hours to talk to all of them. I believe that I shall set Anthony to the task. It will be fine training for him.”

“Emeline can accompany him. As I told you, she has a certain talent for charming answers out of people.”

“As does Anthony. I believe they will make an excellent team. If nothing else, the business is bound to be exceedingly boring. Perhaps it will discourage both of them from pressing on with careers in this line.”

Lavinia sighed. “Do not pin your hopes on that strategy, sir.”

He turned around slowly and gave her a wry smile. “You are right. One long morning of dull interviews is not likely to put either of them off, is it?”

“No. Meanwhile, what shall I tell Howard? To be honest, I am worried about his state of mind, Tobias. He is quite distraught.”

“Why don’t you advise him to seek treatment for his weak nerves?”

“That is not at all amusing, sir.”

“Wasn’t meant to be.”

She eyed him closely. “You really do not care overmuch for Howard, do you?”

“I think the man very likely murdered his wife in a fit of jealous rage,” Tobias said shortly. “No, I cannot say that I am fond of him.”

“I would remind you that you are quite free to quit this case.”

“That is impossible and well you know it.” He came to stand over her, gripped the arms of her chair, and leaned down to put his face very close to hers. “I cannot walk away from it as long as you insist upon being involved in the affair.”

The cold, grim determination in his eyes sent an unaccountable shiver through her. “Why are you so suspicious of Howard? You have no evidence to indicate that he murdered Celeste.”

“I may lack the evidence to support my belief, but I am very sure that your old family friend has ulterior motives in this affair. I am certain that he has no interest in avenging his dead wife. He is using you to help him find that damned bracelet.”

“Rubbish. You took a strong dislike to Howard even before Celeste was murdered. Admit it.”

“Very well, I admit it. I did not like the man one damned bit before his wife turned up dead, and I trust him even less now.”

“I knew it. I could see it in your eyes that first day when I walked into the parlor and found you with him. But for the life of me, I cannot comprehend such instant dislike on your part. What on earth set you so strongly against him right from the start?”

For an instant she thought he would not answer. She was aware of his powerful hands tightening around the arms of her chair. The fierce planes and angles of his face looked as if they had been hewn from stone. There was an implacable, immovable, unalterable quality about him that, in another man, would have sent a shock of dread through her.
