Chapter 1 – Seven Nights in a Glass Vein

The Blood Bank predicts my first murder at eleven minutes past midnight.

At ten fifty-eight, I am hanging upside down from its glass ceiling with a forged inspector’s seal between my teeth.

Below me, a cathedral of suspended blood glows through the dark. Millions of sealed capillaries run from donor vaults to brass prediction engines, each carrying the memory of a crime its owner may one day commit. The city calls this prevention. People who have never been arrested call it peace.

People like me call it a profitable market for alibis.

My own tube hangs in the Pre-Offender Gallery, shelf 9, row 31. I know because a frightened clerk paid me to forge his innocence, then sold my name to avoid his sentence. By sunrise, the Council will read my blood and arrest me for murdering Crown Prince Lucien Draev—a man I have never met and have only considered killing in the abstract.

I cut the ceiling latch and drop onto a curator’s balcony. My boots make no sound. I designed them for adultery investigations and constitutional crises.

The forged seal opens the first gate. The second asks for a living pulse. I press the clerk’s stolen heartbeat cylinder to the sensor. The third gate asks me to state my lawful purpose.

“Routine calibration,” I say.

The lock turns green. Machines, unlike priests, only care whether a lie has the correct paperwork.

Inside the gallery, glass veins climb thirty stories. Each tube bears a name, probability, date, and victim. I pass a baker predicted to poison his brother in twenty years, a child expected to kill an unknown soldier, and a surgeon whose blood has forecast the same mercy killing every month since her patient recovered.

My tube waits behind black sovereign glass.

MARA VEY.

MURDER PROBABILITY: 97.4%.

VICTIM: LUCIEN DRAEV.

TIME TO EVENT: SEVEN NIGHTS.

The memory inside shows my hand driving a silver stiletto through a man’s heart. The prince’s face remains hidden, but I recognize the ring on my finger. It belonged to my mother and was confiscated nine years ago when a false prediction convicted me of conspiracy.

Someone did not merely forecast the murder. Someone dressed the future in evidence stolen from my past.

I slide a diamond wire around the tube.

“If you cut that,” a man says behind me, “every artery in this gallery closes.”

I do not turn. “Your security briefing needs revision. Threats should come before the intruder touches the expensive object.”

“You have not touched the expensive object.”

Cold fingers close around my wrist.

He moves without disturbing the air. One moment I am alone; the next my back rests against a velvet coat and a silver blade lies beneath my jaw. Lucien Draev smells of winter stone and old smoke. His face is sharper than the propaganda portraits, his eyes red only at the edges, as if hunger is a secret he disciplines rather than a condition he suffers.

“Mara Vey,” he says. “Professional witness. Amateur burglar. Future regicide.”

“Future victim,” I correct. “You should be more polite.”

He rotates my wrist and sees the forged seal. “Who sold you an inspector’s cipher?”

“Your inspectors. Most institutions fail at the human layer.”

His mouth nearly smiles. Then the gallery bells strike eleven.

Lucien removes my wire from the tube and studies the memory. When my predicted hand enters his chest, his grip tightens—not from fear, but recognition.

“That stiletto is mine,” he says.

“Wonderful. The murder is vertically integrated.”

“It was buried with my brother.”

The bank lights shift from red to white. Somewhere in the engine, a clerk has noticed a sovereign file open after hours. Lucien pulls me through a maintenance arch just before mirrored guards enter the gallery.

“You are helping me escape?”

“I am moving a suspect to a room with fewer witnesses.”

“Romantic.”

He takes me into the donor crypt, where royal blood is stored in tubes as thick as tree trunks. No Council clerk is permitted here. Every vampire ruler has deposited memories to prove continuity of mind across centuries.

Lucien stops before his own vein.

The glass is black.

“Royal predictions are sealed,” I say.

“Not from royal blood.”

He opens his palm against the lock. The vein clears and projects a future across the crypt walls.

I see Lucien standing at the center of the city beneath an artificial dawn. Bodies fill every street. His mouth is red. His hands hold the broken controls of the Blood Bank while towers burn around him.

MURDER PROBABILITY: 100%.

VICTIMS: UNRESOLVED POPULATION SET.

TIME TO EVENT: SEVEN NIGHTS.

My smaller prediction tube begins vibrating in my pocket. I did not take it, yet it is suddenly there, warm as living skin. Lucien looks from the city’s massacre to the glass bearing my name.

“Someone linked the forecasts,” I say. “If I kill you, your massacre cannot happen. The bank has turned me into its correction.”

“Or you are the person who creates it.”

Footsteps gather beyond the crypt door. Council voices order the prince to surrender the intruder. Lucien could hand me over and preserve his throne for another seven days.

Instead he bars the door.

“Predictions cannot be edited without a memory exchange,” he says. “Someone fed the bank a future that has already been lived.”

“Time travel. Excellent. Ordinary corruption was becoming dull.”

He takes my stolen tube. When his thumb touches the glass, a memory jumps between us: his brother laughing in a graveyard; me at nineteen, learning that evidence can be manufactured more easily than innocence. The exchange lasts a second and leaves a clean absence behind his eyes.

“What did it take?” I ask.

Lucien searches his mind. “The reason I once trusted the Council.”

The cost frightens him. He hides it beautifully.

The crypt door buckles under a silver ram. We have seven nights to find whoever rewrote our blood. Each clue may require another exchange, and each exchange will erase one of the moral memories keeping Lucien human.

He offers me the silver stiletto from inside his coat—the same weapon the bank places in my future hand.

“If I become what the prediction shows,” he says, “you will use this.”

I accept the blade. “And until then?”

The final hinge tears free. White execution light pours through the gap.

Lucien’s fangs descend as he turns toward the door.

“Until then, Miss Vey, try not to murder me before we discover who wants you to.”
