Six nurses had quit in five weeks, and one of them had fled Liam Mercer’s mansion crying so hard she forgot her coat.

The ground floor of the Mercer mansion on Astor Street was an echoing mausoleum of gilded cornices, dark oak wainscoting, and armed discipline.

It was 9:15 PM.

The scent of lemon floor wax and expensive Cuban tobacco hung heavy in the central hall, masking the faint, persistent undercurrent of gun oil. Every thirty minutes, two men in dark tailored suits and tactical earpieces patrolled the perimeter of the marble gallery, their steps heavy and deliberate, their hands resting flat over concealed shoulder holsters.

I walked down the grand curved staircase carrying an empty stainless-steel dressing tray and a sealed biological hazard bag containing Liam’s debrided bandages.

At the bottom of the landing, the double mahogany doors of the library stood ajar, spilling warm amber light and the murmur of low, heated voices onto the parquet.

"The teamsters at Berth Nine are refusing to unload the reefer containers without a direct signature from Liam," a voice rasped—Leo, the grizzled, sixty-year-old head of estate security who had hired me off the street three weeks ago. "They know he hasn't been seen on the river in five weeks. The rumor on the street is that he's already in a coma, or dead in an unmarked plot in Wisconsin."

"Then we forge the manifest signatures, Leo," a second, smoother voice replied.

It was Marcus Vance.

At thirty-eight, Marcus looked like an investment banker who had wandered onto the waterfront and discovered he had a natural gift for extortion. His bespoke charcoal three-piece suit fit his broad shoulders without a crease, his silver-dusted dark hair styled with surgical precision, a gold signet ring flashing on his right pinky finger as he poured himself three fingers of Macallan 25 from a crystal decanter.

"If the freight sits on the dock another forty-eight hours, the refrigeration units fail and we lose nine million dollars in pharmaceutical imports," Marcus continued, his cultured baritone smooth as machine oil. "We tell the local stewards that Liam had a private conference in Zurich. We execute the shipping covenants under my power of attorney."

"Liam never granted you power of attorney over the maritime slips, Marcus," Leo said, his gravelly voice hardening.

"He didn't need to," Marcus murmured, taking a sip of his scotch. "The bylaws of the Mercer Logistics Trust state clearly that if the managing director is incapacitated for more than thirty consecutive calendar days... executive authority vests immediately in the vice-chairman."

Marcus paused, setting his crystal glass on the edge of the mahogany desk with a sharp, resonant clink.

"And tomorrow morning at sunrise, Leo... is day thirty-one."

I stepped through the doorway, my white nursing clogs squeaking deliberately against the polished floorboards.

Both men snapped their heads toward me. Leo’s hand dropped instinctively toward his jacket, but he relaxed when he recognized my scrub top. Marcus Vance, however, did not relax; he turned his cold, predatory blue eyes onto me, his face arranging itself into that polished, patronizing smile he used whenever he spoke to the domestic staff.

"Ah, Nurse Nora," Marcus said, leaning his hip against the corner of the partner’s desk. "How is our patient this evening? Still throwing water carafes at the plaster?"

"Mr. Mercer's temperature is ninety-nine point two," I replied, keeping my cadence clinical, monotonous, and completely devoid of inflection. "The wound drainage is serosanguinous, the margins are contracting, and his white blood cell count dropped by four thousand units on the afternoon lab draw."

Marcus’s smile tightened at the edges—an almost imperceptible twitch of irritation around his thin lips that only an emergency room nurse trained to spot micro-expressions would have caught.

"Is that so?" Marcus asked softly. "A remarkable recovery for a man with four inches of surgical steel bolted through his femur. Dr. Vance told me this morning that chronic osteomyelitis was virtually guaranteed."

"Dr. Vance is a private surgeon on your retainer, Mr. Vance," I said, setting the metal tray down on the console table by the door. "I am an acute trauma nurse with five years of septic shock management. If you irrigate a wound with high-pressure saline and broad-spectrum vancomycin instead of letting it sit in damp gauze, tissue heals. Even tissue that someone expected to rot."

Marcus took two slow, measured strides toward me, stopping three feet away, his towering frame attempting to cast that heavy, suffocating shadow of male entitlement over my space.

"You're very dedicated to your duties, Nora," he murmured, his voice dropping into an intimate, transactional register. "Especially for a woman whose younger brother is currently scheduled for an experimental T-cell transfusion at Children’s Memorial on Friday morning."

My breath seized in my throat.

My knuckles tightened against the hem of my cotton scrub top, my nails digging into my palms until the pain kept me grounded.

"You investigated my brother's medical chart," I said, my voice dropping an octave, cold and level as a frozen lake.

"I investigate every variable that enters this house, my dear," Marcus smiled, reaching into his breast pocket and pulling out a heavy, cream-colored bank envelope stamped with the gold seal of the Northern Trust Bank.

He held it out toward my chest.

"There is one hundred thousand dollars in certified cashier's drafts in this envelope, Nora," Marcus whispered, his eyes glittering with cold, venomous calculation.

"Ten times what Liam Mercer pays you for a week of changing dressings. It covers Tommy’s clinical trial in full, with enough left over for private rehabilitation in Arizona."

I looked at the envelope. Then I looked up into Marcus Vance’s dead, arrogant eyes.

"And what does one hundred thousand dollars buy, Mr. Vance?"

"Simple nursing oversight," Marcus said, his smile spreading across his patrician face like oil over water.
