I woke up in a bar I did not recognize, on a chair that smelled of stale beer and regret, with a headache that felt like someone was driving railroad spikes through my temples. The neon sign outside the window buzzed in a language I almost understood. Rain lashed against the glass. Everything was gray. Everything was wet. Everything was wrong.

I knew my name was Jack Lin. I knew I was a jeweler. I knew I had come to New York two years ago, fresh out of the service, with a duffel bag full of memories I could not quite remember and a pair of steady hands that could make gold do anything.

But I did not know how I had gotten to this bar in Chinatown. I did not know why my wallet was empty. I did not know why my left hand was trembling.

The bartender, a heavy-set Italian with a scar running from his ear to his collar, slid me a glass of whiskey. "You been here all night, Mr. Lin. Waiting for somebody."

"Who?" My voice was a stranger's.

He shrugged. "A lady. Chinese. Beautiful. She left hours ago."

The name hit me like a bullet: Yvonne.

I had met Yvonne Chen three months ago, maybe four. Time had become slippery since then. She had appeared in Chinatown like fog rolling over the bay—suddenly everywhere, then suddenly gone, leaving everything damp and changed. She rented a storefront on Canal Street and opened a jewelry shop that smelled of jasmine and old money. The signs said she sold jade and gold, but everybody in the neighborhood knew the real product was something else.

She was beautiful in a way that made men stupid. Not the loud, flashing beauty of the nightclub girls in Midtown, but something quieter and more dangerous. She wore qipaos cut from silk so fine it looked like water. She spoke in a voice that sounded like honey poured over ice. And when she looked at you—with those dark, bottomless eyes—you felt like she was reading something inside you that even you did not know was there.

I was her newest customer. Or maybe her newest victim. I still did not know which.

She hired me to repair her grandmother's jewelry—a collection of pieces that had clearly seen better centuries. I worked on them in her back room, which smelled of incense and something else, something animal and ancient. She would sit across from me, watching, her chin resting on her hands, her fingers tapping a rhythm on the table that matched the ticking of my tools.

"You have steady hands, Jack," she said one evening, as I was re-setting a jade stone into a gold dragon. "Steady hands are rare. In the war and in peace."

"I learned in the army," I said. "Field repair. You learn to work with what you have."

"I like that," she said. "You work with what you have."

She started bringing me more than repairs. She brought me designs—sketches of jewelry that had never existed before. A necklace with a pendant shaped like a nine-tailed fox. A ring with nine sapphires arranged in a spiral. A bracelet with nine clasps, each one depicting a different animal in flight.

"Who designed these?" I asked.

"My grandmother," she said. "Or my great-grandmother. The family stories are unclear."

"What do they mean?"

She smiled. "That depends on who is asking."

The first man to disappear was Mr. Wu, the triad boss who controlled Chinatown's gambling dens. He had been Yvonne's customer for years, and his body was found in the Hudson three weeks after he stopped showing up at her shop. The police ruled it a drowning. The triads ruled it a betrayal. Nobody ruled it Yvonne.

The second man was a real estate developer named Frank Russo, an Italian who had been trying to buy out Chinatown block by block. He lost his fortune in a single afternoon—every investment went bad, every deal collapsed, every bank called in his loans. He was evicted from his penthouse and moved to a studio in Queens. I saw him at the bar one night, staring into a glass of cheap whiskey, his eyes hollow.

The third man was a socialite named Victoria Ashworth, who had hosted a party at Yvonne's shop after seeing one of her jade pieces in Vogue. She came back from the party and fired her entire staff, sold her apartment in Greenwich Village, and moved to a monastery in upstate New York. When a reporter from the Times tried to interview her, she said only one thing: "She showed me what I really am. And I could not unsee it."

I should have been afraid. I was afraid. But I was also in love with her, or something that felt like love, and fear is a poor barrier when what you want is right in front of you.

One night, she kissed me. It was after midnight, raining, the shop closed, the neon sign outside casting a pink glow through the blinds. She took my face in her hands and kissed me like she was trying to memorize the shape of my mouth.

"Jack," she whispered. "You are different from the others."

"Different how?"

"You remember things."

The words followed me home like a ghost. I started looking at my life with new eyes. My wallet had been empty that night at the bar. My hands were trembling. I could not remember the last three months in detail—only fragments, like a film reel with pieces burned away.

I went to see Detective Russo, an Italian cop I had met when a gang of thieves had tried to rob my shop. He was a good man, tired but honest.

"I need your help," I said. "I think I am losing my memory."

He studied me over his coffee. "Since when?"

"Since I started working for a woman named Yvonne Chen."

His face changed. Not with fear—with recognition. "How long have you known her?"

"Three months. Maybe four."

He leaned back in his chair. "Jack, I have been investigating Yvonne Chen for two years. She has been in this country since at least the 1930s. Maybe longer. Every city she touches, something happens. Men lose everything. Women forget why they were angry. Children stop speaking. And she moves on, always moving on, always beautiful, always alone."

"Is she dangerous?"

He smiled without humor. "Mr. Lin, everything that walks on two legs and smiles is dangerous. The question is whether you are smart enough to see the teeth before she bites."

I went back to her shop the next day. She was not there. The back room was empty—no jewelry, no sketches, no smell of jasmine. Just dust and a single white hair on the table, impossibly soft, that would not come off no matter how hard I scraped it.

On the wall, written in what looked like pencil but felt like fingernails, were the words: YOU REMEMBERED TOO MUCH.

I left Chinatown that night. I do not know where I am going. I do not know if I am running toward something or away from it. But I know one thing: in my coat pocket, I found a bracelet this morning. Nine clasps. Each one depicting an animal in flight. And underneath the clasp, engraved in tiny characters I could not read but somehow understood:

Thank you for remembering, Jack. But some things are better forgotten.

The rain has not stopped since I got to this city. I do not know which city. I do not know my name anymore. But sometimes, in the reflection of a window, I see a woman in a qipao standing behind me. And when I turn around, there is nobody there.
