I knocked on the door. A lanky servant, awkward in what should have been elegant green-and-gold livery, did a terrible job disguising his surprise at finding a caller. He assured me his mistress and her daughter were at home, and urged me to follow him. I waited in a wide corridor while he secured permission for me to enter.

When I entered the sitting room, Mrs. Sanders and her daughter shared similar drawn expressions on faces gray with worry. Polly’s eyes, swollen and red, lacked all sparkle. Her mother, dignified and old-fashioned, stood to greet me.

“Lady Emily, I am more grateful than I can say to see you. As you must imagine, our plight is such that most of society is unwilling to receive, let alone call on, us.”

“I’m so sorry.” I ran my hands along the cool, smooth surface of the horsehair sofa upon which I sat. “My heart goes out to you, Polly. Have you heard from Lord Thomas?”

“His father wrote, ending the engagement,” Mrs. Sanders said. Polly sniffed behind a handkerchief. “Their family cannot tolerate such a connection.”

“Forgive me, Mrs. Sanders, if I speak out of turn. I know not the truth of Polly’s birth, but it seems to me irrelevant. You have never questioned her position as your daughter. Why should anyone else?”

“You’re very kind,” she said. “But we both know discretion is essential in such matters. Society will accept nearly anything so long as it’s not spoken aloud. Once such a secret’s out, however…”

“Have you any idea who might be responsible for the rumor?” I asked.

“It’s no rumor, you may as well know. These things happen, and distraught though I may have been at the time, I can’t say I was surprised. We sent the maid off, of course, but my husband wanted the baby to enjoy the same benefits and comforts as his other children. How could I object?”

Polly fidgeted in her seat, wrenching her hands.

“It’s admirable that you did not,” I said.

“I enjoyed having a little girl to spoil,” she said. “Sons are what we’re told to want, but after seven of them, I was happy for a daughter, and I’ve loved Polly as much as I would have had she been my own. Now, though, our whole existence is shattered.”

“It’s dreadfully unfair,” I said. “I know it’s difficult, but can you think of anyone who might have wanted to harm your family by exposing your secret?”

“Not at all. My husband is to receive a knighthood. We’re an honorable and much-respected family.”

“Yet someone did this to you,” I said. “We must figure out who it was.”

“For what purpose?” Mrs. Sanders said. “I can’t see how it will do anything but extend the life of the scandal. We’re going to take Polly abroad. Summer on the Continent and winter in Egypt. We’ll not return to England until this talk has quieted.”

The talk might quiet, but Polly’s reputation would never recover. No doubt her parents were hoping to find, during their travels, a respectable enough gentleman in need of cash, someone willing to overlook the accident of Polly’s birth in favor of her father’s wealth, and agree to marry the girl. If they did not succeed, she had a year, possibly two, before she’d be doomed to the lonely life of a spinster.

“Did you know Mr. Michael Dillman?” I asked.

“I’ve heard the name, but can’t say I’m acquainted with the man,” Mrs. Sanders said.

“He was murdered this week. And before his death, someone painted his door and stoop with red paint, just as someone has done to yours.”

“Murdered?” She gasped, alarm stretching her thin features. Her daughter shuddered. “I had no idea. I’ve been too consumed by our own troubles to read the papers. Do you think we’re in danger?”

“I don’t have evidence one way or the other,” I said. “Although it appears this villain has already done his damage to you. Were you acquainted with Mr. Dillman, Polly?” I asked.

“I know his fiancée better. We were all occasionally at the same parties, and Cordelia might have introduced us. I can’t say I remember.”

“Was he friends with Lord Thomas?” I asked.

“Not so far as I know,” she said. “They both could have belonged to the Turf Club. Lord Thomas spends loads of time there.”

I made note of the information, determining to find out whether Mr. Dillman was also a member, although it seemed unlikely. He hadn’t been known for aristocratic connections and I couldn’t imagine he would have much enjoyed the company he’d find there. “You and Mr. Dillman both have been singled out by someone with brutal intentions. Can you recall any other connection you or Lord Thomas might have with him?” I asked.

“I don’t see any point in thinking further about Lord Thomas,” Mrs. Sanders said.

Polly lowered her eyes as they filled with tears. “I’m doomed, aren’t I?”

“I don’t know,” I said, knowing full well the unforgiving nature of society and not wanting to deceive her. “But I promise I will do everything I can to help you.”

“I don’t feel safe in these circumstances,” Mrs. Sanders said. “Not after a murder. I must speak to my husband at once about pushing forward our departure for the continent. Will you excuse me, Lady Emily? Please know how deeply I appreciate the gesture you’ve made by calling on us. The significance of a woman of your rank and reputation maintaining civil ties with us after this devastating incident will not be lost on society. I thank you for that.”

I wished there was more I could do for Polly, but there is little that offers respite from a well and truly broken heart. When, heavy with sadness, I stepped back into shade-filled Kensington Palace Gardens and headed for the park, I saw Ivy standing across the street from me. She waved.

“Emily!” she called, beckoning me to her. “You’ll never believe what’s happened.”

“Have you been waiting for me?” I asked.

“Yes, Colin told me where you’d gone. I thought you’d never come out.”

“You could have come in, Ivy,” I said. “The Sanderses are in dire need of friends at the moment.”

Her pretty face clouded. “You’re right, but I’m not so brave as you. I will call on them, I promise, truly. But you wouldn’t have wanted me there this afternoon. I never would have been able to refrain from telling you what happened.”

“What?”

“You’ll agree, I’m sure, it wouldn’t have been appropriate to mention this in front of Mrs. Sanders.” She twirled the handle of her lacy parasol as we walked.

“I can’t agree if you don’t tell me,” I said, knowing my friend sometimes needed coaxing, especially when she had something important to say.

“Right.” She took my arm and guided me along the pavement in the direction of the park. “Red paint has been found on another doorstep.” She spoke with a measured but deliberately dramatic flair.

“Whose?” I asked.

“The Mertons’,” Ivy said. “Lady Merton’s laughing about it. I saw her earlier on Rotten Row. But everyone’s already speculating.”

Lady Merton, one of the most celebrated hostesses in London, lived, so far as I could tell, a blameless life.

“What are they saying?”

“It must be something her husband’s done. She’s as harmless as they come. But it’s all very strange, don’t you think?” She tilted her head closer to me. “And rather a bit exciting, in a terrible way.”

“Not exciting for the victims,” I said.

“I didn’t mean to be cruel.”

“Of course you didn’t, darling,” I said. “You don’t have a cruel bone in your body. I understand what you’re trying to say. It’s unsettling and exciting all at once. But we must not forget it’s damaging as well. Lives have been ruined and we don’t know what will happen next.”

“It makes me half afraid to look at my own doorstep every morning.”

“You can’t be worried, Ivy. You’ve nothing to hide.”

“Everyone has secrets, Emily.”

The Sanders family may have found a measure of relief in the attention given to the Mertons over the following days. Polly’s birth was no longer a mystery and the story had grown tiresome. Society was now focused on speculating what secret scandal might have inspired this new splash of red paint. Theories had been circulating for nearly a week when I came down to breakfast and found Colin waiting for me, the London Daily Post spread out on the table at my place.

“I thought you’d want to see this right away,” he said.

I put aside my copy of The Aeneid, to which I’d been glued for weeks. After nearly a year of constant study with my friend, Margaret, who was currently holed up in Oxford with her new husband, I’d become invigorated with my newfound competence in Latin. While Greek would always be my passion, it was a pleasure, sometimes, to be free of the challenges posed by a different alphabet. Virgil’s epic was particularly satisfying to me because I liked to see something good happen to a Trojan. Lots of bad happened, too, of course—this was mythology. But if I couldn’t have the Trojans victorious over the Greeks, I was happy to see one of them become so culturally significant to the Romans. What would Julius Caesar, who claimed Aeneas as an ancestor, have done without the legitimacy provided by the mythical hero?

I bent over the newspaper. A paid advertisement took up an entire page but it was not there to suggest one should buy a certain type of bonnet or shoes. Nor did it beg the reader to visit an attraction or show. Instead, it contained the text—almost lurid text—of a series of love letters. Bold type highlighted a dozen characters:

T E R C N O M L K A E R.

“I don’t understand,” I said.

“The letters are signed only with initials—M or C,” Colin said. “Now study the bold bits.”
