Paris — October 1885

  The ferry docks at Calais as dawn breaks. I don't look for the woman among the passengers—somehow I know she's already gone, traveling by methods I can't guess toward destinations I can't imagine.

  But she'll be back—she said so—and when she returns, I'll have questions.

  Seven months since the black water. Seven months since Mei pulled me from the beach and began turning grief into purpose. Four names crossed off the list already—Webb, Cross, Blackwood, Garrett—each one a small victory against the congregation that tried to drown me.

  Fourteen names remain. The next one lives in Paris, and he has no idea I'm coming.

  And now I have a mother to find.

  I step off the ferry with my scholar's bag heavy on my shoulder—books I'll never read, blades I'll certainly use, and a file on a man who smiles while children drown. The locket pulses once against my chest, warm and strange, a new weight I'm still learning to carry.

  Paris in autumn smells of bread and revolution.

  The train from Calais deposits me at Gare du Nord as evening falls, and the city spreads before me like a fever dream—grand boulevards lined with chestnut trees dropping their leaves in showers of gold and rust, cafés spilling amber light onto rain-slicked cobblestones, the restless energy of a place that believes itself the center of the world. Gas lamps flicker to life along the Seine. Somewhere nearby, someone is playing an accordion, the melody threading through the clatter of carriages and the calls of street vendors packing up for the night.

  Seven months ago, I was a scholar's daughter who cried over dead cats and carried spiders outside instead of killing them. Now I'm something else entirely—something with thirteen marks carved beneath my ribs and four deaths already carved into my conscience. Something that walks through crowds and calculates sight lines, escape routes, the distance to the nearest water.

  The marks stir as I move through the crowded streets, responding to the moisture in the air, the rain-slicked stones, the river Seine flowing through the heart of the city like a dark artery. Paris is built on water—the river, the canals, the ancient wells that still feed fountains in hidden courtyards, the catacombs that flood when the rains come heavy. The network spreads beneath the cobblestones like veins beneath skin, and my marks sense every thread of it.

  The Deep One's attention surfaces briefly—curious, perhaps, about what I'll do in this new place—then settles back into its eternal patience. I've grown used to that attention over these months, the abyss pressing against the edges of my consciousness. It's not watching, exactly. More like listening. Waiting to see what its investment produces.

  Let's find out together, I think, and somewhere in the depths, cold amusement ripples through the dark.

  Mercer. His name is Victor Mercer, and he's the next one to die.

  The file Mei gave me includes everything: his daily routines, his known associates, his position in the congregation's hierarchy. He's mid-level—important enough to be trusted with ritual preparations, but cautious enough to have hired protection since the deaths began. Two former soldiers who live in his house and accompany him everywhere. A harder target than my first kills.

  But the file also includes photographs. And when I look at his kind face, his gentle eyes, I think about the cup he pressed into my hands seven months ago. The warmth in his voice as he told me to drink.

  His name is Victor Mercer, and he's the next one to die.

  Mei's file described him in careful detail. Fifty-eight years old, retired scholar, presents himself as a gentle academic interested in folklore and mythology. Gray hair, kind eyes, a rumpled manner that puts people at ease. The sort of man who would help a lost child find her parents, who would give up his seat on a crowded omnibus, who would never dream of hurting anyone.

  Except he has hurt people. Hundreds of them, over thirty years of service to the congregation.

  His specialty is preparation. He's the one who meets the children before the ritual—who gives them water, tells them stories, holds their hands while they walk to their deaths. The last kind face they see before the horror begins. The final lie they're told before the truth swallows them whole.

  I remember his smile. Remember the cup he pressed into my hands in that cold stone room, the warmth of his voice, that studied gentleness with which he said drink this, child, it will help you sleep. I remember believing him, for just a moment, because his voice was so soft and his eyes were so warm and I was so scared and so desperate for someone to be kind.

  The water tasted like copper and salt. Like the sea, but wrong somehow. Like the sea if the sea hated you.

  I was sixteen years old, trusting a stranger's kindness. I won't make that mistake again.

  My boarding house Mei arranged is in the Latin Quarter, three floors above a bookseller who asks no questions and keeps irregular hours. Stairs creak as I climb, each step announcing my presence to anyone who might be listening. Third step from the bottom: sharp crack. Seventh step: low groan. The landing outside my door: silence, the boards worn smooth by decades of feet. I make a note of all of it—useful information for late-night departures.

  My room is small but clean. A narrow bed pushed against the wall, a washstand with a chipped basin, a window that looks out over rooftops and chimney pots stretching toward the distant bulk of Notre-Dame. The kind of place a young scholar might stay while researching at the Sorbonne. The kind of place no one will remember when I'm gone.

  I unpack my things with methodical care, the routine Mei drilled into me until it became automatic. Books on the shelf—philosophy, folklore, maritime history, nothing that would seem unusual for a student. Clothes in the wardrobe—plain dresses suitable for academic work, nothing memorable, nothing that would make someone look twice. And the blades, hidden in their usual places: one beneath the mattress where my hand can find it in the dark, one wedged behind the washstand where I can reach it while washing my face, one strapped to my thigh where it always lives, a constant pressure against my skin.

  Mei taught me this. Never be more than a second away from a weapon. Never assume any room is safe. Never let your guard down, not even when you're sleeping, not even when you're alone, not even when every instinct says there's nothing to fear. The congregation has eyes everywhere, and what they can't see, they can often guess.

  When I'm finished, I sit on the bed and study Mei's file on Mercer.

  He lives in the Marais district, in an apartment above a pharmacy owned by a cousin who may or may not understand what his relative really is. The congregation tends to keep its members close—families who've been involved for generations, networks of obligation and complicity that make betrayal difficult and escape nearly impossible. They marry within the faith. They raise their children in the faith. They die in the faith, and what waits for them after death... I try not to think about that. The glimpses I caught in the black water were enough.

  He hosts salons twice a month. Gatherings of folklore enthusiasts who discuss obscure myths and ancient rituals without ever mentioning what those rituals actually involve. Respectable academics debating the symbolic meaning of sea-serpent legends while their host knows exactly what lurks in the deep. Perfect cover for a man who spends his life preparing children for sacrifice.

  He takes his coffee at the same café every morning at nine. Walks through the Jardin du Luxembourg every afternoon at three. Attends mass at Saint-Sulpice every Sunday, kneeling in the same pew, reciting the same prayers to a God who surely cannot hear him over the screaming of the children he's helped murder.

  A man of habits. A man of routines. A man who believes his patterns make him safe.

  He's wrong.

  I don't sleep that night. The marks won't let me.

  They pulse with the rhythm of the Seine, with the water in the pipes, with the rain that starts falling around midnight and doesn't stop until dawn. Every time I close my eyes, I see the black water rising. Feel the hands on my shoulders, pushing me down. Hear the voice that said drink this, child, and the other voices, the ones that chanted in languages older than French, older than Latin, older than anything human.

  So I sit by the window instead and watch Paris sleep. Watch the gas lamps flicker and the rain fall and the occasional late carriage clatter past on the cobblestones below. I think about Thomas Garrett on the cliff path, about the surprise in his eyes when he recognized me. About the way he begged at the end, all that respectability stripped away, just a frightened man facing the thing he'd helped create.

  The void where feeling used to live doesn't fill. It never fills. But around its edges, purpose grows like scar tissue over a wound.

  Fourteen names—thirteen after Mercer, twelve after that. The arithmetic of vengeance, simple and clean. By the time the sun rises, I have my plan.

  The café is small and warm, tucked into a corner of the Rue de Seine where the morning light filters through windows streaked with condensation. I arrive at eight, an hour before Mercer's usual time, and settle into a corner table with a cup of chocolate I don't want and a book I've memorized the first page of. Playing a role. Being invisible.

  At nine-oh-three, he arrives.

  My marks flare the moment he walks through the door, heat spreading in my chest like a brand being pressed to raw flesh. They remember him even if he doesn't remember me—one child among hundreds, one face among all the faces he's smiled at before the deep claimed them.

  He's exactly as Mei described. Gray hair neatly combed. Spectacles perched on a nose that's been broken at least once. The rumpled clothes of a scholar who cares more about ideas than appearances. He moves through the café with the comfortable familiarity of a regular, exchanging greetings with the proprietor in rapid French, settling into what is obviously his usual table with the easy confidence of a man who has never been hunted.

  He orders coffee—black, no sugar. The waiter doesn't need to ask.

  I watch him over the edge of my book, careful to let my gaze slide past him rather than fix on him directly. He looks like someone's grandfather. The kind of man who would slip you sweets when your parents weren't looking, who would tell you stories before bed, who would hold your hand when you were scared and tell you everything would be fine.

  He used that smile on dozens of children. Used it to make them drink the water, eat the bread, believe his lies. Used it on me, in that cold stone room, while the chanting built and the black water waited.

  Drink this, child. It will help you sleep.

  He finishes his coffee. Pays his bill with coins he counts out carefully—the habit of someone who's lived through lean times, or perhaps just the methodical nature of a man who does everything precisely the same way every single day. He tips the waiter. Gathers his satchel. Walks out into the morning light like a man without sins.

  I don't follow—not today. Today is for watching and learning, for becoming certain.

  The sigils burn below my heart, and I consider kind smiles and gentle voices and the way monsters can look like anyone at all.

  Fourteen names remain, and his is next.

  And somewhere behind me, in the shadow of a doorway I didn't check, a figure watches me watch him. Taking notes. Sending reports.

  By now the congregation knows someone is hunting their people—they just don't know it's me. Not yet.
