Julian began to understand these were not separate misfortunes. Someone had been circling the house for weeks, patient and precise, and Margaret's arrival had somehow set all of it into motion.
The children, without meaning to, became the ones who pieced it together.
Lucas, walking back from the stables one evening, overheard two men near the property line speaking low and fast. He caught only fragments, a date, a name he did not recognize, and twice, unmistakably, the words "the music box." He ran the whole way back to tell Julian, breathless, no longer angry, only afraid.
Emma remembered something too, hesitant at first, unsure if it mattered. Weeks earlier, she had seen a figure leaving Margaret's room through a servant's corridor rarely used, moving quickly and careful not to be seen. She had not thought much of it then. She thought of nothing else now.
Oliver, who forgot very little of what he overheard, recalled a conversation from his very first week at the manor. Two grooms had murmured about old papers hidden "where music sleeps," a phrase that had meant nothing to a boy obsessed with beetles and horses. It meant everything now.
Julian sat with all three accounts laid out before him like pieces of a puzzle he was only beginning to understand the shape of. The fire, the ledgers, the bribed footman, the missing box. None of it added up to simple theft.
"This was never about money," he told Margaret, the two of them alone in his study long after the household had gone quiet. "Someone has been hunting that music box specifically for a long time, I think. Longer than you have been here."
Margaret's hands were folded tightly in her lap. "It was my husband's. He left it to me before he died. I never thought..." She stopped and shook her head. "I don't understand what could be inside it worth all this."
"Neither do I," Julian admitted. "But I intend to find out."
There was no formality left between them in that moment. No employer and governess, no duke and widow separated by rank. Only two people who had both lost someone, both frightened for the children they loved, and both determined not to lose anything else.
"I will help you search," Margaret said. "Whatever this is, I want to know."
Julian looked at her for a long moment. "You don't have to."
"I know." Her voice was steady. "I am choosing to."
They began that night, working side by side through old estate records, servants' logs, anything that might explain who wanted the box badly enough to burn down a stable for it. Hours passed. The candle burned low. At some point, their shoulders were nearly touching over the same ledger, and neither of them moved away.
It was, Julian realized, the first time in years he had not faced trouble alone. Not as a duke protecting his household, not as a widow protecting her children, but as partners.
Just before midnight, a horse collapsed at the front gate, its rider barely clinging to consciousness. A stranger, bloodied, had been sent from miles away. With his last breath, the dying messenger managed only one sentence.
"Your husband died protecting the Duke."
The messenger died before he could say anything more.
Julian sat with Margaret through what remained of that night, neither of them sleeping. The man's final words repeated between them like something too heavy to set down. Your husband died protecting the Duke.
It made no sense. And yet it explained too much to be dismissed.
By morning, they had a name from the messenger's coat pocket: a solicitor's card, water-stained but legible, belonging to a man in London who had once handled correspondence for Margaret's late husband. Julian sent word immediately, along with instructions to search the bribed footman's belongings one final time before he was handed over to the magistrate.
It was Emma, of all people, who found the answer first.
Sitting with the music box's twin, a smaller carved box Margaret had kept separately, a gift from her husband early in their marriage, Emma noticed the base did not sit flush with the sides. She showed Julian, who ran his fingers along the seam and found a hidden catch cleverly disguised in the scrollwork.
Inside was a false bottom. Inside that, folded tightly enough to survive years of hiding, were letters, estate maps, treasury records, and signed confessions.
They spent the whole afternoon reading them, and by the end, the manor felt like a different house entirely.
Margaret's husband, it turned out, had not died in the carriage accident she had always been told about. He had been investigating, quietly and at great personal risk, the death of Julian's father, the previous duke, years before Julian himself had ever suspected anything but grief.
The letters detailed months of careful work, financial discrepancies buried in the estate's books, a pattern of theft disguised as bad harvests and failed investments, and finally proof that the old Duke's death had not been the accident everyone believed.
The name behind it all was one Julian had trusted without question for most of his life: his longtime steward, the man who had run the household since before Julian could walk its halls, who had taught him to ride, who had stood beside him at his father's funeral and later his wife's.
The steward had orchestrated the theft. When the old Duke grew close to discovering it, he had arranged his death and allowed an innocent groundskeeper to hang for the crime.
Margaret's husband had uncovered the truth. He had gathered the evidence carefully, meaning to bring it to Julian directly. But before he could, he was killed, made to look like an accident just as the old Duke had been. The evidence was hidden inside the one place no one thought to look: a widow's grief, carried inside a music box she never stopped keeping close.
Julian sat with the papers in his hands for a long time, saying nothing.
