Chapter 1 - The First PulseThe kitchen of Bello Rosso had gone completely silent, the background symphony of clattering dishes and roaring burners replaced by a heavy, suspended tension.

I kept my fingers pressed against Rafael Corbin’s wrist. His skin was cold, damp with a fine layer of sweat, but his pulse was the real tell. It was sluggish, slipping down into the dangerously low bradycardic range. Aconitine doesn’t wait for anyone to finish their meal; it hijacks the nervous system with terrifying precision, binding to voltage-sensitive sodium channels and locking them wide open. The heart forgets how to beat in a steady rhythm.
"Sixty-two," I muttered, tracking the beat against my own internal clock. "Dropping toward fifty."
Eli burst back into the private dining room, nearly tripping over the threshold, clutching a small plastic bottle and a heavy bag of medical-grade activated charcoal from our back-of-house emergency safety kit. Right behind him, Damon slammed a fresh gallon of bottled water onto the mahogany table.
"Open his mouth," I ordered.
Damon didn't hesitate this time. Whatever authority Rafael held, the boss had made his choice, and his men followed suit. Damon knelt, supporting Rafael’s head with a practiced, heavy grip, prying the older man’s jaw open.
"Mix four tablespoons of the charcoal into half a bottle of water," I told Eli, my voice cutting through the panic in the room. "Not too thin, or he'll aspirate."
As Eli frantically shook the bottle, mixing the pitch-black slurry, I looked up at the older man with the sharp brown eyes—Vincenzo, Rafael’s longtime second-in-command, a man whose reputation for quiet violence was whispered about across the entire East Coast.
"If the atropine doesn't arrive within five minutes," I said quietly, locking eyes with him, "his heart will arrest. The charcoal will bind whatever is left in his stomach, but the alkaloid is already moving into his bloodstream. Do you have a doctor on speed dial who understands raw botanical extraction, or are you going to let a dishwasher save your boss's life?"
Vincenzo’s expression flickered, a mixture of cold calculation and reluctant respect. "Just keep him breathing, Dr. Hart."
My real name hung in the air like a ghost. I didn't ask how he knew it. In the criminal underworld, information was currency, and Vincenzo was a billionaire broker of secrets.
"Swallow," I urged Rafael as Eli handed me the blackened mixture.
Rafael’s eyes fluttered open, dark and fiercely defiant. With a monumental effort of will, he swallowed the slurry. A streak of black ran down the corner of his lip, staining his pristine white collar. It was an undignified end for a kingpin, but it bought us time.
Sirens wailed faintly in the distance, growing louder by the second. Eli stood by the door, pale-faced, watching the street.
"They're coming," Eli whispered. "The private medic is three minutes away."

"Tell them to stay back," I said, wiping my hands on my apron, standing up slowly so my joints popped in the quiet room. "If paramedics walk in here and see a poisoned mafia boss, they'll call the federal authorities before they check his pulse. You don't want an investigation. You want a recovery."
Vincenzo stared at me for a long, agonizing beat. Then, slowly, a dangerous, appreciative smile touched the corners of his mouth.
