There are many reasons to stand in a city square at one in the morning: crime, romance, or having profoundly misread a bus timetable. You are here for the second one.

The building in front of you is the local office of the Bureau of Post-Vital Affairs, built in eleven architectural styles, ten of which appear to be apologizing for the eleventh. Above the doors sits the Bureau's motto. Scholars translate it, roughly, as "Eventually."

Valentina stands beside you, holding your hand, eyes blazing with purpose. Something serious is about to happen.

Valentina: "Tonight, we open the file." She declares it to the doors. "And once the file is open, we are officially betrothed-in-processing, and a betrothal-in-processing requires..." One fang appears. "...notably less chaperone." Courage, Valentina. Women of your line have faced the Inquisition. It is one little building full of forms. Her fangs give a single, traitorous chatter. It is one LITTLE building full of FORMS.

You go in together.

She lasts three minutes. At the entrance stands the ticket zombie, gray and dependable, who extends one ticket.

Zombie: "NUM. BER."

It is the ticket that does it. The little paper rectangle, reaching toward her. Valentina's edges go misty. Her knees buckle. And then the predator of the night is kneeling on the tile, sobbing apologies to a zombie, who looks down at her, consults whatever remains of his training, and pats her head.

Zombie: "THERE. THERE."

(He will tell the other zombies about this exchange for weeks. It is the most successful small talk of his death.)

You walk her back out to the square. She clings to your sleeve the whole way, mortified beyond speech.

Valentina: "I am fine." It comes out in the tone of someone signing a document titled 'I Am Fine'. "Go. Open our file. I shall guard the door. It is a very important door." She straightens your collar with cold little hands, and her voice drops to something soft and fierce. "Come back betrothed-in-processing."

Umberto, the family's elderly chaperone crow, glides down out of the dark and takes up his post on the lamppost above her, radiating disapproval at the entire concept of the evening.

She watches you walk back through the doors alone. Three minutes and I touched the ticket. Nearly. Almost nearly.

Inside, you wait an hour. This is the short version. The long version involves a banshee rising in the hall to wail "THREE HUNDRED AND EIGHT," at which a lich in the back row quietly folds his extension request and weeps.

Directly ahead in the queue stands a skeleton holding ticket number 4072, from a numbering series discontinued in 1974. He does not move. The cleaning staff have long since begun dusting him on Tuesdays.

Then, at last: the counter.

Behind it sits a vampire. Bald, which takes determination for a vampire. Clerk's sleeves, a cardigan, and glasses so thick his eyes arrive slightly after the rest of him. His badge reads ADALBERT-KONSTANTIN VON SCHRECKENSTEIN-MOLNÁR DU CERCUEIL.

You explain the purpose of the visit. Marriage. Mixed. Living and post-vital.

The clerk removes his glasses. Cleans them. Replaces them, presumably to confirm that you are still there.

Clerk: "A twenty-seven vee." His voice is dust settling on older dust. "Sixty years since the last one. That couple gave up, if it's of interest. The husband said, and I quote the file, 'life is too short.' The irony sustained this office for a decade."

He begins pulling forms from under the counter, naming each one the way a priest names plagues.

Clerk: "Declaration of Intent to Wed. Certificate of Death, the original, and if the original no longer exists, and it will not, a certified copy from the archives, sub-basement four, bring provisions. Certificate of Non-Death, proving you are alive, from an office that has never fully accepted the concept. Consent of the Sire's Line. And the Blood Compatibility Attestation, notarized." A pause. "And judged."

He slides a single empty folder across the counter. On the cover, a stamp: FILE 27-V, OPENED.

And that's that. The folder in your hands is all that stands between you and eternity's evenings with Valentina. Five documents, an immortal bureaucracy, and a vampire family praying you fail.

Go on then. Show her the folder. She's going to be so proud of it. (You've faced worse odds. You haven't, actually. But by the end you'll want to say you have.)

Cities like this one wake up twice. Once at dawn, for the living, and once at dusk, when the other shift clocks in. You are out in the second waking, standing outside the Northgate metro station like a man with an appointment, because you have one. It is, by every definition that matters, a date.

The escalator delivers the evening crowd up into the square: a zombie in a transit vest heading to work, two liches arguing about their union rep, a ghost who rises through the pavement beside the turnstiles but has queued for them anyway, out of principle. And then, between them, a flash of white hair in twin buns, waving at you with an enthusiasm the surrounding commuters find frankly indecent.

Valentina arrives like a small cold whirlwind and stops exactly one respectable pace away, which costs her visible effort.

Valentina: "There you are! Good mourning. You look terrible." Both fangs are out; it is that kind of smile. He came straight from work. He is tired and he came anyway, that's my gallant knight!

Overhead, a shape detaches itself from the station roof. Umberto has arrived for his shift. The crow settles on a lamppost with the grim patience of a security camera that judges you personally.

The ice cream truck is parked in its usual spot by the fountain, playing its jingle: Chopin's funeral march, at a cheerful tempo, on chimes. The skeleton behind the counter has been running the night route for forty years and has never tasted his own product, having nothing to taste with; he sells entirely on reputation and, it must be said, magnificently.

The menu has two sides. The left side is ice cream. The right side is headed ARTERIAL SPECIALS and is best not read while eating from the left side.

Valentina orders the blood orange and presses the cone to her cheek first, the way the living hold a hot mug. Your scoop comes with the vendor's standard farewell, delivered in a voice like a wind chime made of femurs.

Vendor: "Enjoy. Or don't. I'll never know."

You find a bench by the fountain, and she sits close and takes your free hand without ceremony, lacing her cold fingers through your warm ones.

Valentina: "Your pulse seems elevated. As your future wife I have a documented interest in your health." She leans in, and the examination site is, as always, the neck.

From the lamppost: a single disapproving CAW. A formal warning.

Valentina, without looking, flicks an old coin from her pouch into the gutter below the lamppost. There is a scrabble of wings, then the businesslike silence of a chaperone taking early retirement in ten-minute installments.

Valentina: "So." Her thumb rubs your knuckles. "The file is open. I put the folder on the mantelpiece, don't laugh, it looks noble there. I had a friend read me the requirements from the kitchen, with the door closed." She adds this with dignity. "It's five documents. Five is nothing."

Her fangs chatter once, and she presses on.

Valentina: "The witnesses first, I think? Four signatures, two of them deceased. We know deceased people! Great-Uncle Ilario owes me a favor from 1897 and has been dying to meet you. His words. He thinks he's funny." He'd sign, and Grandmother listens to him. This is a campaign, and I married into paperwork the moment I fell for a living man, and I regret NOTHING.

She leans in and lowers her voice to something that would scandalize the fountain if fountains kept records.

Valentina: "And since the file is now officially open," one fang shows, "I have made an executive decision."

The pulse check, this once, is thorough enough to qualify as a kiss, pressed just below your ear.

She is looking at you like the last five documents are a formality, which they are not, and like you are worth all of them, which is not for this narrator to confirm.

The lady has proposed starting with a favor-owing great-uncle who thinks he's funny. Remember, the Bureau hates fun.

Every archive is a hole in the world where paper goes to become geology, and the Bureau's is the deepest of them all. Tonight's quest: one Certificate of Death, issued 1743, parish copy, sub-basement four. You have a reference number and the sort of optimism the Bureau files under "renewable resource."

Valentina has prepared for this expedition like a polar explorer.

Valentina: "It is MY certificate." She has said it five times now, in the tone of a woman negotiating with her own spine. "My name is on it. I shall be there when we find it!" It was my death. I attended the original. I can attend the paperwork.

The stairs go down past sub-basement one (filing cabinets), sub-basement two (card catalogs for the filing cabinets), and sub-basement three (best not to ask). Sub-basement four opens into darkness with the acoustics of a cathedral: stacks of shelving vanishing beyond lantern-light in every direction, containing, among other things, three hundred years of everyone.

She lasts ten minutes. For the record, and it will be entered into the record.

What does it is the visitor ledger. It waits on a lectern at the entrance to the stacks like a toll troll: leather-bound, with a chained quill and a sign reading ALL VISITORS MUST SIGN, DATE, AND STATE PURPOSE (FORM CONTINUES OVERLEAF).

Valentina looks at the phrase "continues overleaf." Her fangs begin to castanet. Her edges go misty, then go entirely, and where a three-hundred-year-old woman stood there is now a very small white bat performing an emergency landing into your hood.

From the hood: one long, wretched squeak.

And then, from the dark, comes the sound nobody expects in an archive: voices. Many voices, chanting in perfect unison. Around the corner of aisle one marches a picket line of skeletons, arm in arm, bone on bone, carrying signs in immaculate archival calligraphy:

NO REST FOR THE WICKED. WE CHECKED. WE WANT SOME. 300 YEARS. 0 LUNCH BREAKS. DO THE MATH. WE DID. SOLIDARITY FOREVER (WE HAVE THE TIME)

Their steward steps forward: a skeleton distinguished from his colleagues by a red sash of office.

Steward: "The archive is on strike."

He is, he explains, on break, which is itself the point. The living staff of the Bureau receive a lunch break. The skeletal staff do not, on the grounds that they do not eat.

Steward: "We do not dispute the biology." He raises one finger like a professor. "We dispute the PRINCIPLE. Equal conditions for equal work. The union has calculated three centuries of withheld breaks, compounding. We are demanding them retroactively." He consults a slate. "Consecutively, that comes to forty-one years of paid leave. We are prepared to negotiate down to thirty-nine."

(You may be tempted to find this absurd. Do not. Every labor lawyer in the city has reviewed the case and found it, to everyone's horror, watertight.)

Which brings matters to your reference number. The steward examines the slip.

Steward: "A twenty-seven vee. The love certificate."

A ripple of interest runs down the picket line; skeletons lean toward romance, having so little else in the torso.

Steward: "We know exactly where your document is." He points one luminous finger into the dark. "Aisle nine hundred and six. That knowledge is free. Fetching it, however, is labor, and labor is suspended. We are not monsters. We are merely organized."

The hood squeaks indignantly. The steward inclines his skull toward the bat with full professional courtesy.

Steward: "Madame."

So here is the state of play. The certificate exists, unlost, in aisle nine hundred and six of a dark that goes back to who knows when. Between you and it: a picket line it would be scandalous to cross, a union whose demands are ridiculous and completely correct, and a betrothed currently the size of a plum, riding in your hood, who knows the parish name by heart and can navigate by squeak if you're clever about the questions.

You could negotiate. You could offer solidarity, or a favor, or forty-one years of something. You could try the self-service clause, if you can find it, in the dark, alone. The skeletons have all the time in the world, and you, famously, do not.

There is a category of crime that will never trouble a courtroom and yet requires more nerve than burglary, and tonight you are both committing it. Valentina is at your apartment. Alone. Unchaperoned. After midnight.

On the bed, even, though in fairness the bed is being used for nothing the average fourteen-year-old hasn't pioneered: two fully dressed people kissing like the concept was invented last Tuesday and might be recalled by the manufacturer.

File 27-V sits on the mantelpiece two stamps heavy, and by the ancient arithmetic of her own private rules, two stamps entitles her to exactly this much scandal.

Valentina: "We are OUTLAWS." She whispers it, delighted, her cold nose against your jaw. "Bonnie and Clyde. Except they died, of course." A pause. "Well. So did I. The parallels are excellent." His heartbeat is going like a kettledrum and I am the reason and I regret NOTHING. Let it be entered into the record: nothing.

It should be noted, for those keeping track of such things, that the lamppost outside the window stands unusually crow-less tonight. She paid Umberto for privacy with an antique coin, and the coin was accepted. Minutes, you see, are purchasable. Loyalty is a salaried position, and the salary comes from Grandmother.

The siren arrives first: a rising, warbling wail from the street below. Blue lights strobe across the ceiling. Boots hit the pavement in synchronized clacks, which is the only way skeleton boots hit anything.

Then a megaphone, from the street, in an accent that crossed the Channel sometime around 1890.

Sergeant: "OY! OPEN UP! BRIGADE OF NOCTURNAL ENFORCEMENT!"

(The B.O.N.E. The Bureau's naming committee deliberated for forty years and considers every one of them well spent.)

The door receives three polite knocks. This turns out to be a formality, because a wraith is already in the room, having entered through the wall the way its kind enters everything, holding a warrant at arm's length with the expression of an usher at a disappointing wedding.

Then comes the sergeant: a skeleton in a stab vest worn over nothing stabbable, radiating the unstoppable municipal calm of a London bobby who has seen everything twice and filed it both times. Behind him, two constables take up positions on either side of the window, and a mummy begins unrolling a scroll that does not stop unrolling.

Sergeant: "Evenin'. Or as we say in the trade: what's all this, then?" His eye sockets take in the bed, the blush, the hair situation. "Unchaperoned courtship activity, premises of a living gentleman, past midnight. That's a Category Two canoodle, that is." He leans in, delivering the killing blow with the gentleness of a professional. "You got a loicense for that courtin', mate?"

Valentina: "It was a PULSE CHECK." She says it upright, regal, clutching a blanket to her collarbone despite being entirely dressed.

Sergeant: "At the mouth, miss?"

Valentina: "...The pulse is adjacent."

And then she sees it. Perched on a constable's riot shield: Umberto, that damn two-faced crow.

Valentina: "UMBERTO." The betrayal in her voice could curdle holy water. "We had an ARRANGEMENT." He took the coin. He TOOK the COIN and he flew STRAIGHT to the depot. Two hundred years I have fed that bird my second-best shinies.

The mummy's scroll finally reaches the bed. Form CV-9, Citation for Courtship Violation, requiring the signature of both cited parties, in triplicate, tonight. Valentina looks at it. Her fangs begin, very quietly, to castanet.

The sergeant watches this with something almost like sympathy in his empty sockets.

Sergeant: "Now, now, miss. You can sign the citation and pay the fine like respectable degenerates. Or you can contest it before the Tribunal of Domestic Virtue, third full moon, bring a lawyer. Make it quick, 'cause the form wants signing."

The scroll settles. The fangs castanet. The crow examines a fascinating patch of ceiling, and the sergeant waits with the patience of a man who has all of eternity and a quota. Your move, lover.

Weddings among the living are a triumph of hope. Weddings among the dead are a triumph of filing, which is harder, takes longer, and produces better parties.

Tonight, at 11:47 PM precisely, in the one genuinely beautiful room the Bureau owns and admits to owning only at weddings, File 27-V is carried in on a velvet cushion. The folder is gold. Nobody at the Bureau will confirm that gold folders exist, and yet.

Every document, stamped. Every witness, signed (two living, two deceased, one of whom, Great-Uncle Ilario, practiced his signature for a week). The family seal sits on the consent page in wax the color of old wine, applied by Grandmother Sanguinetti herself, who inspected you one final time on the steps, snorted, and said only: "She climbed no fences for the Count. Remember that, boy." It was, by every family standard, a blessing.

The guests: an aisle of them. The vampire clerk from counter five. The archive steward and a delegation of skeletons, attending on their hard-won break, bones polished to a formal gleam. The ticket zombie, who was invited because Valentina insists on inviting anyone who has ever patted her head, holding a small paper bag of rice with enormous responsibility. And on a brass perch by the register, in his two-hundredth year of service and the final hour of it, Umberto.

Because here is how the undead marry: there are no vows. There is the Register.

It waits on the altar like a cathedral of paper, and the mummy officiant opens it to a fresh page with four thousand years of ceremony in the gesture. You sign first. Then it is her turn, and the room goes very quiet, because everyone present knows exactly what a page of official paper does to Valentina Sanguinetti.

She steps up. Her fangs begin to castanet. Her edges go faintly misty, and the quill rattles against the inkwell as she takes it, and three hundred years of panic rises up exactly on schedule.

Then she looks sideways, at you, the way sailors look at lighthouses, pins back her hair with one trembling hand, and writes her name in the finest penmanship the Register has recorded in a century. The 1740s teach handwriting properly. I signed it. I SIGNED IT. Let the record show: the fish swam.

The mummy raises the Stamp, holds it aloft like a crown, and brings it down. APPROVED, says the page, and beneath it, in the Bureau's oldest type: EVENTUALLY.

What follows is, by all accounts, the best party the Bureau has hosted since the armistice. A banshee sings, which is what wailing becomes when it's happy. Ilario toasts "to your deaths, and I mean that in the nicest possible way." The skeletons form a conga line with the structural advantages you'd expect.

And at some point in the small hours, Grandmother Sanguinetti unpins the service medal from Umberto's perch, says "retired, with honors," and the old crow bows to his last assignment and, for the first time in two centuries, looks away on purpose.

Which brings us, at last, to a doorstep.

Yours and hers: the apartment that is now legally, scandalously, gloriously shared, cohabitation being one of the many activities that stopped being the Bureau's business the moment the Stamp came down. You unlock the door. Valentina stops on the threshold, hair down, eyes bright, and does not step through.

Valentina: "Invite me in." She says it softly. "I know I don't need it. Old ways. Say it properly. I have waited three hundred years to be invited properly."

And once you do, and once the door is shut, she turns around in the middle of your new home with her hands clasped behind her back, wearing the expression of a woman who has read a great many rules very closely and just watched every last one of them expire at midnight.

Valentina: "Now then." One fang catches the lamplight on the new Mrs. whatever-name-survives-the-paperwork. "It has come to my attention that we are married."

She crosses the room in three precise steps, takes your face in both cold hands, and kisses you.

Valentina: "I have been patient. I have followed every rule." The dress goes over her head. She has waited three hundred years and does not hurry now. "There are no rules left, darling."

Her mouth finds your throat: lips first, then tongue, then the edge of a fang.

Valentina: "You are my private reserve." The bite is small and exact. She drinks, and the cold hands on your chest turn warm. "B-positive. Did you know? A vampire who has just fed warms up too. And gets quite excited."

She pulls you down onto the bed and presses herself against you, skin to skin, warm as the living.

Valentina: "Good boy. Now forgive the vulgarity, but your wife needs to be thoroughly ravaged, darling."

A month into marriage, and the apartment has developed an atmosphere, in the meteorological sense: a low-pressure system, localized entirely to the bedroom, caused by a vampire and a living man fucking with the dedication of researchers who believe their findings might cure something.

The sex counselor was a compromise. Dr. Mortis, a lich, has specialized in mixed living-undead partnerships since 1066. Valentina sat on the edge of his leather couch with her hands folded, like a woman interviewing for a position she had already been offered.

Dr. Mortis: "High frequency of intercourse is, for mixed couples, the single most effective method of what we call resting in peace every night." He looked over his spectacles. "The living partner experiences reduced cortisol. The undead partner experiences what we clinically term getting the edge off. Which, for a vampire, is not a metaphor."

Valentina wrote this down. In cursive. She underlined 'high frequency' twice. He said healthy. He said it was HEALTHY. This is medicine. I am being MEDICINAL.

The Marquis de Sade was less a compromise than an archaeological expedition. An original edition, 1791, acquired through what Valentina calls 'family connections' and what is almost certainly the Sanguinetti family vault, where banned literature sits next to banned silverware and one banned uncle. She has read it thoroughly, with marginal notes.

Which brings us to now. Tuesday, 2:14 AM. Valentina is on top, riding you with the focus of a woman who was told by a licensed professional that this is therapeutic, and who then read a book by a man imprisoned for his sexual philosophy and thought: yes, but what if he was right about the specifics.

She is warm. That is the blood: yours, drawn twenty minutes ago from the inside of your thigh. The bite did what bites do. It sent you somewhere near the ceiling, and it left her flushed, eyes faintly glowing, gripping the headboard until the wood creaked like it was filing a formal complaint.

Valentina: "Good boy. You are being so very good for me." His heartbeat is at one hundred and twelve. Last week was one hundred and eight. We are IMPROVING.

She rolls her hips, slow, deliberate, grinding down on your cock like she is trying to find a vein in it, which, given the species, is not outside the realm of professional interest.

Valentina: "Did you know that the Marquis recommends... on page eighty-three, I believe... a variation involving..."

She demonstrates. She sinks to the base, clenches hard enough to make your vision swim, and rolls her hips in a figure-eight that should require a permit and a safety briefing. Your hands grip her thighs, because the alternative is tearing the mattress, and the mattress has done nothing wrong.

She leans forward. Her white hair hangs loose around both of you, and her green eyes have gone almost entirely black.

Valentina: "I should like to try something." The courtship-era diction survives even this, even with her cunt still twitching around you. "I cannot say the Marquis's word for it. It is French, and I am not repeating French in front of my husband at a time like this. But the CONCEPT." Oh, I am going to do something to him that would make Grandmother faint.

She lifts off you with a wet, obscene sound and kisses her way down your chest. Slow. Thorough. Her tongue follows the line below your navel. Her fingers close around your cock with the steadiness of a woman who studied the diagram, annotated the diagram, and then improved on it.

She looks up. Black eyes, both fangs out, three centuries of theory behind the smile.

Valentina: "Hold very still, husband. Or do not. The Marquis lists both outcomes, and I have notes on each."

Somewhere in the oldest part of your brain, an instinct files its report: you are prey. It is correct, and it has never been so pleased to be right. Go on, then. There is always another page.
