A Conspiracy in Belgravia (Lady Sherlock #2)

“She was spared further suspicion because that particular Mr. Finch turned out to be counterfeit. In which case, of course she wouldn’t have recognized him. And of course he wouldn’t have known to meet her for their annual glance of longing at the Albert Memorial.

“But throughout it all, I never fully trusted Lady Ingram. I have always felt, from the very beginning, that she was not the kind of person to love deeply—not in a romantic sense, anyway. So there was always this tension between what I considered to be her character and the story she told of the impossible longing that contradicted everything I knew about her.

“Then there was the question of her choice of private investigator. She didn’t go to someone else, she came to Sherlock Holmes, who had worked closely on an infamous case with Inspector Treadles, a man who is well known to her husband. How certain could I be that she didn’t know that I was Sherlock Holmes, and that Myron Finch was my half brother?

“If she did know, it would have meant that I was specifically chosen for that connection. And if she knew of that connection, then it meant she knew a great deal more of Myron Finch than she admitted. But just because she was less than forthcoming didn’t imply she harbored ulterior motives. She might have feared that I wouldn’t help her if I knew she wanted my help specifically. She might also have felt herself incapable of facing the judgment of others were she to confess how much effort she, a married woman, had put into searching for a man who wasn’t her husband.

“My reservations about Lady Ingram were shunted to the side while we tried to understand why Mr. Marbleton was impersonating Mr. Finch. That is, until Miss Redmayne and I spoke to my father’s solicitor and learned that Lady Ingram had been to see him. This meant she did know which family he was connected to—and probably a great deal more. But it wasn’t until the Marbletons sought refuge here, after having been ambushed at Mrs. Woods’s, that my suspicions concerning Lady Ingram began to solidify.

“Lord Ingram first informed me that Mrs. Watson’s house was being watched. I had thought that it was Moriarty, on the off chance that our movements might lead him to the wife who had escaped his clutches. But now I began to wonder, what if it was someone connected to Lady Ingram, trying to see if following me would lead directly to Mr. Finch?

“In the days after we first discovered that our movements were being watched, we acted with a great deal of care. As time passed, we became less careful. There was every possibility that the surveillance had been pared back when we were being deliberately evasive—and then resumed when we let down our guard. And that I had led Lady Ingram to Mr. Marbleton’s address without meaning to.”

“You’ll remember that I had come to you with the theory that the Marbletons were impersonating Mr. Finch in order to get close to the Holmeses, to find out what they might inadvertently know—and that the real Mr. Finch was the man murdered in Hounslow. I had connected the Marbletons to Moriarty because of a similar scheme of codes that they used, and my theory was brought down when Lady Ingram definitively stated that the dead man wasn’t Mr. Finch.

“But then Stephen Marbleton confirmed that at least some of my conjectures were correct—namely, that Mr. Finch had worked for Moriarty. That the dead man in Hounslow had been his colleague under Moriarty. And that together they had defected, taking something important from Moriarty at their departure.

“It was quite a leap to consider that Lady Ingram might be tracking down Mr. Finch for Moriarty. On the other hand, she was perfectly placed. You have no one close to you, so in the short term, at least, she was their best bet, a highly intelligent woman who is bored by Society and antagonistic toward her husband, who happens to be not only your brother but your most trusted ally.”

At this, Lord Bancroft downed another cup of tea.

Lord Ingram was tight-lipped and meticulous. But his wife, however estranged, lived in the same household. He kept a diary, which, even if written entirely in code and with everyone important referred to by aliases at all times . . . Well, codes were made to be broken and codes suitable for frequent usage even more so. And should he be away and the diary out of the house, he still wrote his children frequently and the envelopes would give his wife a good idea as to the locations where he carried out assignments.

When he stopped trusting her with his affections, he had believed that would be enough to keep him safe.

Charlotte stirred her tea. “I visited my father’s solicitor a second time to find out when exactly Lady Ingram went to see him. And the answer was three weeks before she came to see me. In Mr. Finch’s old village, a man had come asking for his news at about the same time. I could make the argument that she passed on the information to Moriarty and he had sent the man. But that would be only speculation.

“I mulled a plan to speak to ladies Avery and Somersby, to check the age of the rumor that Lady Ingram had once fancied someone unsuitable. But even if I found out, and the rumor turned out to have been recent, it would only give me more circumstantial evidence.

“There was, however, one way to test whether she worked for Moriarty: If she did, she would know how to decode a message from him.

“I spoke to Lord Ingram. He was, needless to say, highly displeased with me, from the first revelation that I’d tried to help Lady Ingram track down her erstwhile beau, to my final suggestion that he do what he could to find out whether she had pledged her allegiance to someone the crown considers an enemy and a threat.”

Little wonder. The last time he’d put his wife to the test, he’d found out that she’d married him only for his money.

Charlotte reached for the muffin again. “And the rest you know.”

Lord Bancroft’s lips curled humorlessly. “Did it not occur to you, Miss Holmes, to give me this information last we met?”

Charlotte met his gaze squarely. “I owed Lord Ingram an immense debt of gratitude. I do not believe he would have appreciated what you would have done to the mother of his children.”

“The mother of his children is now a threat to us all.”

“I’m sure he took that into consideration.”

At this Lord Bancroft rose, went to the sideboard, and served himself a healthy draught of Sherlock Holmes’s best whisky. “I do not know all the rest. I do not know, for example, Mr. Finch’s current whereabouts.”

Charlotte took a ladylike sip of her tea. “Of that I haven’t the slightest idea either.”

Lord Ingram had always said that she was the greatest liar he had ever met, a once-in-a-generation talent. Perhaps all the untruths she had ever disseminated had been in preparation for this moment.
