Crackenburne gave the matter some thought and then shrugged. “Not much, I’m afraid. If they are the gentlemen I am thinking of, both are elderly. Both are in ill health. Both are wealthy. They have memberships in this club, but I haven’t seen them here in years.”

“That’s all?”

“I’m afraid so. But I’ll see if I can turn up more information, if you like.”

“I’d appreciate it,” Tobias said.

“I must say, I rather enjoy this detecting business of yours.” Crackenburne picked up his coffee cup. “Almost as interesting as the old days during the war when you conducted your clandestine inquiries on behalf of the Crown.”

“I’m glad that you are amused,” Tobias said. “Personally, I have concluded that my career as a spy afforded me a far simpler and more restful life and put considerably less strain on my nerves than my present occupation as Mrs. Lake’s occasional partner.”

The Banks mansion was a vast, gloomy pile of stone in the Gothic style. Tucked away in a remote neighborhood, it rose several stories above a large, high-walled garden. The narrow windows on the upper floors were shrouded with dark drapes. In Lavinia’s opinion, the structure would have been well suited to a horrid novel featuring specters and the odd skeleton.

“Even if one did not know that the master of the house was slowly decaying inside, one could guess as much from the street,” Emeline said.

“It is a somewhat depressing place, is it not?” Lavinia banged the brass knocker. “But I suppose that is only to be expected under the circumstances. His lordship is dying, after all. And taking his time about it too.”

The housekeeper opened the door and peered out, blinking, as if the sunlight on the doorstep was unexpected and unwelcome.

“We wish to speak to Mrs. Rushton.” Lavinia put her card into the woman’s gnarled hand. “Please give her this and tell her that it is very important.”

The housekeeper stared at the card, as though puzzled by the printing, and then scowled. “Mrs. Rushton isn’t in this afternoon. She’s off getting one of her treatments.”

“Treatments?” Lavinia repeated. “What sort of treatments?”

“Got weak nerves. Started going to one of those mesmerists a few weeks ago. Does wonders for her, she says. Can’t tell the difference, if ye ask me, but the long and the short of it is, she ain’t home today.”

The housekeeper closed the door in Lavinia’s face.

Emeline’s eyes were alight with excitement. “Mrs. Rushton goes to a mesmerist.”

“Indeed.” Lavinia led the way down the steps. She did not trouble to conceal her satisfaction. “A very interesting bit of news, is it not?”

“But what does it imply?”

“I do not know where it will take us, but there is no getting around the fact that it is a connection of some sort.”

Emeline hurried after her. “When will you tell Mr. March about this latest development?”

Lavinia pondered that for a few seconds. “Tonight when I see him at the Stillwater ball. He may well turn up this information on his own. I want to be certain he knows that I got here first. I have no wish to listen to him take the credit. Quite intolerable.”

“I found Oscar Pelling.” Anthony’s voice was strained with the effort to conceal his pride and excitement. “It wasn’t easy. I had to make inquiries at a number of inns before I discovered that he is staying at the Bear’s Head in Shuttle Lane.”

“Excellent work.” Tobias eased aside the carriage curtain and checked the night-shrouded street. It was shortly after nine. The unmistakable stench of the river told him that they were nearing their destination. “Did you learn anything of his business in Town?”

“I spoke with one of the stable lads at the inn.”

Tobias glanced at him, frowning slightly. “I trust you didn’t give yourself away? I do not want Pelling to know that we are making inquiries.”

“Of course I was careful to act very casual.” Anthony looked offended. “Just a bit of conversation about horses and the departure times of the coaches and the quality of the out-of-town gentry who selected that establishment when they came to London. That sort of thing.”

“Well, then? What did you discover?”

“Nothing alarming. As Mrs. Lake guessed, Pelling is here for the usual reasons. He is a man of some substance, after all. He has business with his bankers. The stable lad said he heard him talk about paying a visit to his tailor and boot-maker. Just the customary routine of a wealthy gentleman who does not come to London frequently.”

“Hmm.” Tobias contemplated that information. “The stable lad knew nothing of Pelling’s business affairs, I assume?”

“No, of course not. He’s a stable lad, after all.” Anthony paused a beat. “In terms of personal information, the only thing he volunteered was that Pelling was amusing himself in the evenings with one of the prostitutes who does business in the neighborhood near the inn.”

“Find the woman,” Tobias said.

Anthony swallowed and turned red. “Uh-”

“Something wrong?”

“No, not at all,” Anthony said quickly. “I’ll, uh, pursue that line of inquiry immediately.” He coughed once and cleared his throat. “I’d rather you, uh, did not mention this aspect of the investigation to Mrs. Lake or Miss Emeline, if you don’t mind.”

It dawned on Tobias that Anthony would be mortified if Emeline discovered he was interviewing prostitutes.

“No need to be concerned on that front,” he said. “I haven’t told either of them that we are looking into Pelling’s activities. I do not want to alarm them.”

“Mrs. Lake may not thank you for keeping this from her,” Anthony warned.

“If we discover nothing to concern us, she need not know about these particular inquiries. In any event, when you locate the light-skirt Pelling is bedding, come to me. I’ll handle the inquiry personally.”

Anthony looked considerably relieved. “If you’re sure.”

“I’m sure.” Tobias glanced out the window. “We have arrived.” He rapped on the roof of the hackney, signaling the coachman to stop.

The vehicle clattered to a halt. Tobias opened the door, gripped the edge of the cab, and eased himself down onto the pavement. It was no longer raining, and his leg was in better form today than it had been yesterday, but even on good days he had no great inclination to vault in and out of carriages the way he once had. He told himself that it was the effects of the wound he had suffered in Italy, not the fact that he was perilously close to forty, that caused him to exit vehicles with considerably more dignity than he had employed in his younger years.

“Don’t forget to instruct the coachman to wait for us,” Anthony said. “We don’t want to find ourselves without transportation in this neighborhood. Not at this hour of the night.”

He jumped lightly down to the pavement with a careless ease that made Tobias sigh inwardly.

“We will be only a few minutes.” He tossed some coins to the man on the box. “Be so good as to wait for us.”

“Aye, sir.” The coachman made the coins disappear and reached for his bottle of gin. “I’ll be here when ye’ve finished yer business.”

Tobias walked toward the glowing yellow windows of the tavern. He sensed Anthony’s anticipation.

“Remember, say nothing at all until we are in Smiling Jack’s office,” he said. “Your manner of speaking will give you away instantly in this crowd. Is that quite clear?”

Anthony grimaced. “I assure you, your instructions in the fine art of disguise are as plain this time as they were the other ten times you gave them to me this evening.”

“If I tend to repeat myself, it is because I have good reason. The last thing we need tonight is a brawl with one of the patrons inside.”

“I promise you, I will not say a word.”

Tobias looked at the evil amber glow of the tavern windows and shook his head. “You will never believe it, but Lavinia actually asked me to bring her here to introduce her to Smiling Jack. She planned to disguise herself as a tavern wench.”
