Aspasia’s pedigree, on the other hand, was impeccable. She was the last of her line, and she controlled a substantial inheritance that she had received from her father. At seventeen she had been briefly married to a man some forty years her senior. His death six months after the nuptials had left her with an additional income. Tobias calculated that she was now twenty-eight. The combination of beauty, breeding, and money made her an extremely attractive addition to any guest list. It was not at all surprising that she had received an invitation to Beaumont Castle.

“I’m surprised the housekeeper was able to find a bed chamber for you on such short notice,” he said. “I thought the castle was filled to the rafters.”

“It is quite crowded. But when I arrived and made it plain that there had been a mistake with the invitations,” the butler and housekeeper consulted together. They managed to find a very pleasant room for me just down the hall. I suspect that they arranged to move someone of lesser consequence to a less desirable location.”

“Tell me what this is about, Aspasia.”

She began to pace back and forth in front of the hearth. “I’m not sure where to start. I returned from Paris last month and took a house in Town. Naturally I had intended to call upon you in due course after I was settled.”

He watched her face very closely and decided that he did not entirely believe that last statement. He was quite certain that, if she’d had a choice in the matter, she would have been content to avoid him indefinitely. He understood. She would always associate him with the tragic events of three years past.

“What changed your mind?” he asked.

Her expression did not alter, but her elegant bare shoulders stiffened with tension. It would, he reflected, take a great deal to rattle Aspasia’s nerves.

“Something happened this morning,” she said, gazing into the fire. “Something quite unsettling. I could not think of anything else to do but to consult with you immediately, Tobias.”

“I suggest you come straight to the point,” he said.

“Very well, but I fear you will not credit what I have to say if I do not show you what was left on my front step early this morning.”

She opened a tiny, beaded reticule and removed a small object wrapped in a linen handkerchief. She offered it to him on the palm of her hand.

He plucked the small parcel from her fingers and carried it across the room to examine it in the light of the candle. There he untied the handkerchief and let the cloth fall away.

He looked at the ring that had been revealed and felt the hair lift on the back of his neck.

“Hell’s teeth,” he whispered.

Aspasia said nothing. She folded her arms beneath her breasts and waited, eyes shadowed.

He studied the ring more closely. The band was set with black stones. The darkly glittering gems framed a small gold coffin. He used the tip of one finger to raise the lid. A tiny, exquisitely detailed white skull grinned up at him from inside the miniature sarcophagus.

He angled the ring to read the Latin inscription on the inside of the lid, translating the ancient warning silently to himself. Death comes.

He met Aspasia’s eyes. “It is an old memento-mori ring.”

“Yes.” She hugged herself more tightly.

“You said it was left on your doorstep?”

“My housekeeper found it. The ring was inside a small box covered in black velvet.”

“Was there a note? A message of some kind?”

“No. Just that damned ring.” She shuddered, no longer bothering to conceal her disquiet. “You see now why I went to such lengths to find you tonight?”

“It is impossible,” he said flatly. “Zachary Elland is dead, Aspasia. We both saw the body.”

She closed her eyes briefly in pain and then looked at him very steadily. “You do not need to remind me.”

The old guilt slammed through him. “Of course not. My apologies.”

“Afterward,” she said slowly, “you told me you’d heard rumors of another man who once made a profession of murder, just as Zachary had done, a killer who used the same ghastly signature.”

“Calm yourself, Aspasia.”

“I recall you told me that he was never caught and that there was never any proof of murder in the first place because the deaths always appeared accidental or natural.”

“Aspasia”

“Maybe he’s still out there, Tobias. Maybe-”

“Listen closely,” he said in a tone that finally succeeded in silencing her. “The original Memento-Mori Man, if he ever actually existed, would be quite elderly by now. Dead, most likely. Those rumors dated from decades back. Crackenburne and some of his companions heard them years ago when they themselves were young men.”

“Yes, I know.”

“They eventually concluded that the tale of a professional killer for hire was never anything other than just that, a grisly legend. It was fed by rumors among servants who gossiped in the taverns and told tall tales to their friends. Zachary no doubt took pleasure in invoking the old stories because it suited his sense of melodrama.

“You know how he thrived on excitement.”

“Yes, of course.” The room was warm, but she rubbed her arms as though she felt a chill. “He craved thrills and drama the way some are addicted to opium.” She hesitated. “He no doubt enjoyed re-creating the legend of the Memento-Mori Man. Now it would appear that someone else has the same taste for melodrama.”

“Perhaps.”

“Tobias, I do not mind telling you that I am quite frightened.”

“Obviously someone else knows about Zachary Elland and his connection to you.” He contemplated the miniature skull in the gold coffin. “Are you sure there was no note?”

“I am positive.” She stared bleakly at the ring. “He left that death’s-head on my step to terrify me.”

“Why would he do that?”

“I do not know! A visible shiver went through her. “I’ve been thinking about that question all day. Indeed, I’ve thought of little else.”

She paused. “What if… what if whoever left that ring blames me for Zachary’s death and seeks some sort of crazed revenge?”

“Zachary took his own life when he realized that I was about to have him brought up on charges of murder. You had nothing to do with his death.”

“Maybe whoever left that ring doesn’t know that.”

“Indeed.” But that conclusion did not feel right, he thought. He raised the little skull to the light again. The death’s-head stared back at him with its empty eye sockets, taunting him with its macabre grin. “We must also consider the possibility that this was intended as an announcement of some sort.”

“What do you mean?”

He weighed the ring in the palm of his hand. “You are one of the very small number of people who would comprehend the significance of this ring, because you are one of the few who knew that Zachary Elland styled himself the Memento-Mori Man and used such rings as his signature. I wonder if this is some new villain’s way of telling us that he plans to take up Zachary’s professional mantle.”

“You mean there might be another murderer out there who seeks to emulate the Memento-Mori Man? What a terrible thought.” She paused. “But if that were true, it would have been far more logical for him to leave his calling card with you, not me. You were the one who hunted Zachary down.”

“For all I know there will be a ring waiting for me when I return to Town,” he said quietly. “I set off very early this morning. Perhaps he delivered this ring to you first, and by the time he got to my house I was gone.”

She swung around and took a step toward him, anxiety clear in her eyes. “Tobias, whoever left that ring has something dreadful in mind. If you are right and this is a calling card, we are dealing with a new Memento-Mori Man. You must find him before someone is murdered.”

Lavinia heard a door open as she reached the bottom of the shaowed staircase. Midway along the stone corridor, a wedge of candlelight appeared. A gentleman moved stealthily out of the bed chamber and started toward her.

Yet more traffic. This was not the first time she had been obliged to pop into a closet or hurry around a corner in the past few minutes. The passageways of Beaumont Castle were as busy as a London street tonight. All the comings and goings between bed chambers would have been amusing if not for the fact that she herself was attempting to make her way to a clandestine rendezvous.

It was her own fault, she reminded herself. Tobias had suggested that he visit her in her bedchamber after the house quieted down for the night. It would have been an excellent plan, if she had been allowed to remain in the spacious, comfortable room that she had been given when she and Tobias arrived this afternoon. But earlier this evening, for reasons that remained quite unclear, she had been moved to a very small bedchamber.

She had taken one look at the cot in her new room and realized that it would be extremely uncomfortable for two people, especially when one of them was a man endowed with very fine shoulders. She had informed Tobias that she would come to his room instead, never imagining for a moment that the task would be so difficult to carry out without drawing attention to herself.

She was well aware that most of the guests were not unduly concerned with the prospect of being spotted navigating between bed chambers. It was understood that these sorts of goings-on were to be ignored by passersby. Such was the way of the world when one moved in elevated social circles, she reminded herself.

But she had a feeling that it would not be good for business for a lady who made her living conducting discreet, private inquiries to be seen behaving in a very indiscreet manner. One had to consider the possibility that some of the elegant people who had been invited to the Beaumont estate this week might prove to be future clients.
