The corridor smelled of harsh antiseptic. Two heavy blast doors separated the intensive care unit from the rest of the house.

Evie looked through the thick glass. On the bed lay an old woman, pale and still, tubes running into her arms and throat. The heart monitor was screaming, the lines jumping erratically.

Eight doctors in scrubs crowded around the bed. Sweat beaded on their foreheads. The lead doctor, Dr. Vance, was barking orders. "Push another fifty milligrams of epi! Charge the defibrillator!"

Evie's eyes scanned the monitors. The numbers clicked in her brain. Her pupils dilated.

She stopped walking. She spun around to face Hartwell. "If he pushes that needle, she's brain-dead in ten seconds."

Hartwell's expression turned lethal. He grabbed her wrist, his grip like a vise. "What did you say?"

"It's murder," Evie said, her voice hard, not flinching under his crushing grip.

Beatrice, who had followed them down the hall, let out a nasty laugh. "Listen to her! A street rat giving medical advice." She pointed a manicured finger at Evie. "Dr. Vance is a tenured professor at Johns Hopkins. You don't even know how to spell cardiology!"

Inside the room, Dr. Vance lifted the syringe, aiming for the IV port.

Evie moved. She didn't try to pull away. Instead, her wrist sank a fraction of an inch, and her fingertips jabbed with pinpoint accuracy into the cluster of nerves on the inside of his wrist. Hartwell's grip spasmed open for a split second, a purely reflexive action, and in that instant, she was free. She stepped past him, walked to the wall intercom, and slammed her fist into the safety glass.

Crash.

She hit the override button. Her voice exploded through the speakers in the sterile room. "Stop the injection! Left ventricular free wall rupture, not V-Fib!"

The doctors inside froze. Dr. Vance's hand jerked to a stop. He glared at the glass. "Who is that? Get them off the line!"

Evie rattled off a string of hemodynamic values and echocardiographic markers so fast the words blurred together. "Defibrillation and epi will tear the myocardium. She'll bleed out in seconds!"

Dr. Vance's face turned purple. "That's impossible to diagnose without an echo! This is malpractice!"

Beatrice waved her hand at the guards. "Throw her out! Now!"

Two large men grabbed Evie's shoulders, yanking her away from the wall. Evie's eyes went cold. She dropped her center of gravity, her elbow snapping back, aimed at the guard's floating rib.

"Release her." Hartwell's voice was a gunshot in the quiet hall.

The guards let go instantly, stepping back.

Hartwell walked up to Evie. He stared down at her, his eyes searching her face for any sign of a bluff. Beatrice stamped her foot. "Hartwell! If you let this imposter kill your grandmother, the trust goes to the cousins!"

Hartwell didn't even glance at Beatrice. He reached for the intercom. "Dr. Vance, stop all procedures. Stand down."

He looked at Evie. His voice was rough, heavy with the weight of a life-or-death gamble. "Prove it."

Evie shrugged off his lingering touch. She smirked, then reached out and hit the sensor pad. The blast doors hissed open.

The doors slid apart. Evie walked in, bringing the smell of rain and ozone into the sterile environment.

Dr. Vance stepped in her path, his face red with fury. "This is a sterile field! Security!"

Hartwell stepped in right behind her. He reached back and hit the lock button on the inside panel. The doors sealed shut, locking the guards and Beatrice out.

"She's in charge now," Hartwell said to the room.

The nurses exchanged terrified glances. Dr. Vance sputtered, "I will not be part of this!"

Evie didn't waste a breath. She walked to the scrub sink. She used her foot to pump the disinfectant, lathering her hands up to her elbows in seconds. "Open thoracotomy tray. Bypass machine. Now."

The head nurse looked at Dr. Vance. Vance crossed his arms. "Absolutely not."

Hartwell moved. He pulled a black SIG Sauer from his waistband. He placed it on the stainless steel tray with a loud clatter. The metal rang out in the silent room.

"Assist her," Hartwell said, his voice terrifyingly calm, "or leave the medical profession forever."

The nurse went white. She turned and ripped open a sterile pack.

Evie dried her hands. She grabbed a surgical gown, snapping it on, then pulled on gloves. The entire process took less than ten seconds.

She walked to the bedside. The old woman was gray. Evie picked up a number 10 scalpel.

Dr. Vance leaned in, his voice a venomous hiss. "If you cut her, the pressure will blow the heart apart. It's basic physiology."

Evie ignored him. Her wrist flicked. The blade sliced through the skin and sternum at an angle that looked wrong, almost impossible.

Blood did not spray. The scalpel had missed every torn vessel wall by millimeters.

Dr. Vance gasped, his eyes wide. "That's... that's not possible."

Evie plunged her left hand into the open chest. Her fingers found the back of the heart. She pressed down firmly on the exact point of the rupture.

The monitor above them, which had been racing toward a flatline, began to slow. The erratic peaks smoothed out. The blood pressure ticked up.

Hartwell stood three feet away. His eyes were glued to Evie's face. She was sweating, a bead of it rolling down her temple, but her hands were absolute stone. No tremor. No hesitation.

"Suture," Evie barked. "I'm repairing it on the beat."

Dr. Vance shook his head, backing away. "You can't suture a beating heart. It's suicide."

"Update your textbooks," Evie snapped. Her right hand took the needle driver. The curved needle flashed in the light, moving so fast it left afterimages. Stitch. Tie. Stitch. Tie. Every knot was perfect, microscopic precision under immense pressure.

Hartwell watched the blood on her gloves. Something dark and possessive uncurled in his chest. He had never seen anything like this. She was a machine of pure skill.

Fifteen minutes later, Evie snipped the final thread. She slowly lifted her finger away from the heart.

The organ thumped. A strong, steady rhythm filled the room. The monitor beeped a normal, healthy pace.

Evie stepped back. She tossed the bloody scalpel onto the tray. Clatter. She ripped off her mask, taking a deep breath. She turned her head and looked right at Hartwell, a challenge in her dark eyes.

Silence hung heavy in the room, broken only by the rhythmic beeping of the monitor.

Dr. Vance slumped into a chair. He stared at the closed chest, his mouth open. His voice was a raw whisper. "You... have you studied medicine?"

Evie stripped off her bloody gloves and threw them into the biohazard bin. She walked to the sink and turned on the cold water, scrubbing the dried blood from under her fingernails without looking at him. "Learned a little from a quack doctor."

A little? Vance and the other specialists in the room exchanged glances, their faces burning with shame. What she had just performed was a micro-guidewire interventional therapy, a procedure so delicate they wouldn't have dared attempt it without weeks of preparation. And this woman called her teacher a quack? In that moment, they all lowered their heads, unable to meet her gaze.

Hartwell holstered his gun. He walked up behind her, watching her in the mirror. He reached into his inner jacket pocket and pulled out a black checkbook and a Montblanc pen.

He opened it, signed his name with a sharp flourish, and added seven zeros. He tore the check off and held it out to her.

"Ten million," he said, his tone dismissive, like he was tipping a valet. "Good work. This should buy you a nice retirement, or maybe half that trailer park you came from."

Evie turned off the water. She ripped a paper towel from the dispenser and dried her hands. She didn't even glance at the check.

She turned around, leaning back against the sink. She looked at him like he was an idiot.

"First," she said, her voice flat, "I'm not the idiot you hired. I'm not The Surgeon."

Hartwell’s hand froze, the check suspended in mid-air. A flicker of surprise crossed his features, followed by the ghost of a smile touching the corner of his mouth. "If you're not the miracle worker, then how did you know what to do?"

"I learned from a village doctor," she said, her expression unreadable. "Saw a similar case once. I just copied what he did."

Copied it? Hartwell's eyes narrowed. The fluid, precise movements he had witnessed... that wasn't mimicry. That was mastery.

"Second," Evie continued, "if I wanted money, I'd take it. I don't beg."

She reached out with one finger and pushed his hand away. The check fluttered to the floor.

Hartwell's face darkened. The temperature in the room dropped. He stepped forward, crowding her against the sink. "Then what do you want?"

Evie didn't back down. She tilted her chin up, her eyes boring into his. "I want a favor. From the Barron family."

A wicked smile touched her lips. "Consider it a marker. One I will collect."

The words hit him like a physical blow. His chest tightened. The sheer audacity felt like a spark of electricity straight to his gut.

While he was processing the shock, Evie ducked under his arm. She was too quick, too small. She was out the door before he could react.

In the hallway, Beatrice saw her and shrank back against the wall.

Evie ignored her. She walked down the hall to the guest room Arthur had pointed out earlier. She went inside, slammed the door, and threw the deadbolt. Click.

Hartwell stood in the ICU, staring at his reflection in the mirror. He looked slightly unhinged. He muttered a curse.

He picked up the crumpled check from the floor and threw it into the trash. He walked out into the hall and saw Mr. Slate, his intelligence chief.

"I want everything," Hartwell said, his voice low and dangerous. "By sunrise, I want to know her blood type, her kindergarten teacher, and every sin she's ever committed. Find out who this wolf belongs to."
