The man he'd chosen was a former Scotland Yard detective with eyes that missed nothing. That was the point. Dominic Ashford would see through Vivienne's disguise in days, maybe hours, and the whole farce would be over. She'd come home. She'd be sensible. She'd marry well.

But Dominic Ashford was also dangerous. Not in any criminal sense -- his record was spotless, his reputation impeccable. But the man was reckless, irreverent, and possessed of a magnetism that had left a trail of heartbroken women across two continents. Sending Vivienne to work alongside him was, in retrospect, the equivalent of tossing a rabbit into a wolf's den and hoping the wolf had already eaten.

"He's perfectly safe," Edwin said, and almost believed it.

Outside the door, Margaret the nurse bit down on her knuckle to stifle a laugh. She'd heard every word. She crept away on soft feet, shaking her head.

Vivienne Mercer had no idea what she'd just agreed to.

New York swallowed her whole.

The cab from JFK crawled through Queens, hit the Midtown Tunnel, and spat Vivienne out on East 42nd Street into a wall of noise, exhaust, and humid September air. She stood on the sidewalk with two oversized suitcases and a leather garment bag, watching the city churn around her. Sirens. Horns. A man yelling into his phone about a shipment of artisanal cheese. A woman in four-inch stilettos sprinting for a crosswalk.

London was loud. New York was violent about it.

She found her father's apartment on the twelfth floor of a prewar building on West 54th. The doorman let her in without fuss -- Edwin had called ahead -- though his eyes lingered on her face a beat too long. She was still dressed as herself: black jeans, white t-shirt, hair loose. No disguise yet. She'd made the flight as Vivienne.

That had been a mistake. She realized it the moment the doorman said, "Your father told me to expect a young man. His son."

"I'm his -- assistant," Vivienne improvised. "Vincent will be arriving shortly. I was just dropping off the luggage."

The doorman nodded, unconvinced but uninterested enough to let it go.

The apartment was exactly what she'd expected: clean, impersonal, barely lived in. Edwin spent forty-nine weeks a year at the Blackwood Estate in Connecticut and the remaining three weeks at various expensive locations around the world, all on Alexander Blackwood's dime. This Midtown apartment was a postal address, nothing more.

Two bedrooms. One bathroom with a clawfoot tub and no shower curtain. A kitchen with an espresso machine still in its box and a refrigerator containing a single bottle of sparkling water, expired. The living room had a leather sofa, a television that predated streaming services, and a window overlooking a brick air shaft.

The second bedroom gave her pause. The wardrobe there held two pressed shirts and a pair of dark jeans that were emphatically not Edwin's -- the shoulders were too broad, the cut too modern. Someone had been using this room. Vivienne filed the observation away and moved on.

Home sweet home.

Vivienne locked the front door, pulled the chain across, and went to work.

She opened the first suitcase. Women's clothes on the left. Men's clothes on the right. She separated them into two piles on the bed, then shoved the women's clothing into the back of the bedroom closet, behind a row of Edwin's mothballed suits. If anyone searched the apartment -- and given that she was about to live with a private investigator's attention on her, someone might -- they'd find nothing but men's shirts, men's trousers, and men's shoes in a size too large.

The second suitcase held the real equipment. A high-quality cropped wig in dark brown, hand-knotted on a lace cap, selected with the help of her classmate Priya, who worked part-time at a West End wigmaker. A flesh-toned sports compression binder that flattened her chest to nothing. A pack of adhesive strips for the wig cap. A small case of theatrical makeup -- not much, just enough to add shadow to her jawline and roughen the texture of her skin under close inspection.

Vivienne stripped down to her underwear and stood in front of the full-length mirror on the closet door.

She'd done this hundreds of times. In the RADA dressing rooms, in her flat in Bloomsbury, backstage at the Vanbrugh Theatre before student showcases. But those were performances with defined start and end times. Two hours. Three hours. An afternoon at most.

Three months was not a performance. Three months was a life.

She pulled on the binder first. The compression was tight across her ribs, uncomfortable but manageable. She'd worn them for full rehearsal days and knew how to breathe in them -- shallow, from the diaphragm, not the chest. The key was never to run, never to get winded, never to be in a situation where someone might notice her breathing was wrong.

Next, the wig. She gathered her own hair into a flat coil, pinned it against her scalp with the precision of someone who'd done this a thousand times, fitted the wig cap, and pressed the lace-front wig into place. She adjusted the hairline, blended the edges with a touch of spirit gum. Short dark hair, slightly tousled, falling just above her ears.

She pulled on a loose-fitting white Oxford shirt, left it untucked. Dark jeans, straight-leg, a size larger than she'd normally wear. Brown leather belt. Then she opened the small accessories kit and took out an ascot scarf -- patterned silk, dark green -- and knotted it loosely at her throat.

The ascot was critical. A woman's neck could betray her. No Adam's apple. The wrong proportions. The scarf obscured the evidence while looking like nothing more than an affectation -- a young man who'd spent too long in London and picked up continental habits.

Vivienne looked in the mirror.

A boy looked back. Slim, fine-boned, maybe seventeen or eighteen. Pretty in a way that certain very young men were pretty -- the kind that made older women want to mother them and girls their own age want to date them. The face was androgynous enough to work. The body, flattened and concealed under loose clothing, revealed nothing.

She tried the voice. "I'm Vincent Mercer." Low, rough, with a slight transatlantic accent -- not quite British, not quite American. The voice of someone who'd grown up between two countries. "I'm here to work at Ashford Private Investigations. My father sent me."

Good. Not perfect. The sibilants were still a fraction too soft. She'd need to harden the consonants, push the resonance into her chest rather than her head.

She pulled a face at her reflection -- tongue out, eyes crossed, the way she used to make Priya laugh backstage -- and felt a spike of adrenaline that was part terror, part exhilaration. This was bigger than any RADA exam. This was the role of her life, and the audience was a man she'd never met, a man her father had chosen specifically because he was impossible to fool.

The doorbell rang.

Vivienne flinched. She spun toward the door, then back to the mirror, checking herself once more. The wig was secure. The binder was flat. The shirt hung loose.

The doorbell rang again. And again. And again. Whoever was pressing it had no intention of stopping.

She shoved the remaining women's clothing into the suitcase, kicked it under the bed, and swept the makeup case into the nightstand drawer. The doorbell was now a continuous shriek, the buzzer held down without pause.

"Coming!" she called -- remembered to drop her voice -- and jogged to the front door, catching her shin on the open suitcase in the hallway. Pain shot up her leg. She swallowed the yelp and converted it to a grunt.

The buzzer was still screaming when she undid the chain and pulled the door open.

The man on the other side was still pressing the button.
