Chapter 1 - Yellow Halos

12 world-renowned specialists stood around the city’s most feared man, shaking their heads. Millions of dollars in medical equipment beeped in vain as he wasted away from an invisible killer. The doctors called it incurable organ failure.
The young woman changing his bedsheets did not have a medical degree. She had a desperate need for her paycheck and a grandmother who had once grown the exact poison dissolving him from the inside out.
The monitors beeped in a slow, agonizing rhythm that dictated the mood of the entire Costa estate.
Matteo Costa was dying.
The undisputed head of the local syndicate, a man who had survived car bombs, federal indictments, and 3 separate assassination attempts by rival families, was being defeated by his own body. He lay in the center of a custom-built California king bed, dwarfed by the mattress and the tangles of intravenous tubing snaking from his arms.
Nia Lewis kept her eyes firmly on the baseboards.
She dragged a damp microfiber cloth along the mahogany trim, inching her way around the perimeter of the master suite. Her knees ached. Her uniform, a stiff gray cotton dress that smelled perpetually of bleach and starch, chafed against her collarbone.
She was 24, chronically exhausted, and entirely invisible.
In a room filled with armed men and highly decorated physicians, the maid was practically furniture.
That was exactly how she survived.
Doctor number 12 was a man named Keller, whose consulting fee could have paid off Nia’s entire mortgage twice over. He was packing his leather bag with trembling hands, his forehead shining with nervous sweat.
“I have run the toxicology panels 3 times, Enzo,” Keller said. “Heavy metals, rare alkaloids, ricin, thallium, arsenic. We tested for exotic parasites. We brought in the infectious disease team from Johns Hopkins under NDAs. Nothing is flagging. His liver enzymes are elevated. His heart rate is plunging into bradycardia, and his kidneys are struggling to filter whatever is causing the systemic inflammation. But it’s not an infection, and it’s not any known toxin.”
Enzo stood by the window, blocking out the afternoon sun. He was Matteo’s underboss, a man composed entirely of sharp angles and barely concealed violence. His tailored charcoal suit looked like armor.
“You’re telling me,” Enzo said, keeping his voice dangerously low, “that 12 of the best doctors on the Eastern Seaboard can’t figure out why my boss is dropping 10 lb a week and throwing up bile every morning?”
Keller swallowed.
“I’m telling you we are treating the symptoms, but the root cause is evading modern diagnostics. We can keep him on dialysis. We can manage his heart rate with atropine. But his organs are shutting down. Idiopathic multisystem failure.”
Matteo shifted on the bed. A low, wet groan escaped his cracked lips.
He turned toward Enzo.
Even hollowed out, with dark bruised circles beneath his eyes and cheekbones threatening to cut through his sallow skin, Matteo carried a terrifying gravity. He was not simply a boss. He was an apex predator trapped inside the cage of his own failing flesh.
“Enzo,” Matteo rasped. “Stop threatening the doctor. If he doesn’t know, he doesn’t know.”
“He’s an idiot, Matteo. They all are.”
“Somebody got to you. It has to be the Luces crew. They poisoned you.”
“They don’t have the brains to find a poison that beats a mass spectrometer,” Matteo muttered, closing his eyes. “Send him home. Pay him. Get him out of my sight.”
Keller did not need to be told twice. He snapped his bag shut, nodded stiffly to Enzo, and hurried through the heavy oak doors between 2 silent guards.
Nia wrung out her cloth in the plastic bucket beside her.
The soapy water was murky.
She moved to the next section of wall, keeping her head down while her mind raced.
She had been assigned to the master suite 1 week earlier, around the time the regular housekeeping staff had been barred from the 3rd floor out of paranoia. Enzo wanted a minimal footprint. Nia was quiet, lacked criminal ties, and, most importantly, had no family in the city who could be leveraged.
She was a blank slate.
From the corner of her eye, she watched Matteo rub the bridge of his nose and wince against the dim light filtering through the heavy drapes.
“Everything is yellow,” Matteo mumbled, pressing the heels of his hands into his eye sockets. “Close the damn curtains, Enzo. The glare is killing me.”
“The curtains are closed, boss. It’s pitch-black in here.”
Matteo grunted.
“Then turn off the lamps. They’ve got halos around them. Sickly yellow halos. It’s giving me a migraine.”
Nia stopped scrubbing.
Her hand hovered over the baseboard.
Yellow halos.
She bit the inside of her cheek.
Over the previous 3 days, she had heard Matteo mention them several times. He complained about the lights. He complained that the television screen looked tinted. The doctors had dismissed it as a byproduct of his failing liver. Jaundice affecting his vision, they said.
But jaundice made the whites of the eyes yellow. It did not typically cast yellow-green halos around light sources.
Nia knew that.
Not because she had a medical degree, but because she had grown up in the damp, sprawling forests of the Pacific Northwest with a grandmother who treated modern medicine like a government conspiracy.
Her grandmother had been an herbalist, a harsh woman who grew everything from medicinal chamomile to highly regulated, dangerous botanicals inside a locked greenhouse.
Nia dipped her cloth back into the water and forced her breathing to remain steady.
It was nothing.
She was a maid.
The doctors had run every test in the world.
Who was she to second-guess men with framed Ivy League degrees?
The heavy doors opened.
Carlo entered.
He was Matteo’s cousin, a softer, rounder man who managed the family’s legitimate real estate holdings. He always wore a sympathetic, slightly pathetic smile.
He carried a silver tray holding a steaming porcelain teacup and a small crystal pitcher of honey.
“I brought the tea,” Carlo said softly, setting the tray beside the bed. “Echinacea, ginger, and the special blend. Just like you asked, Matty. It’ll settle your stomach.”
Matteo opened 1 eye.
“My stomach feels like it’s full of broken glass.”
“Carlo, drink it, please. You have to keep something down. The doctors said hydration is key.”
Carlo poured honey into the dark, fragrant liquid and stirred slowly. The silver spoon clinked gently against the porcelain.
Nia picked up her bucket.
Her shift was over.
She backed toward the door, keeping her eyes averted according to the rules.
As she passed the bedside table, a faint, familiar scent drifted toward her.
It cut through the medical antiseptic and Enzo’s sharp cologne.
Earthy. Slightly bitter. A strange sweet undertone.
Instantly, Nia was back inside a damp greenhouse in Oregon.
She stopped.
Her worn sneakers gripped the carpet.
The scent was unmistakable.
Yellow halos.
Plunging heart rate.
Nausea.
Vomiting.
A poison capable of evading standard heavy-metal and synthetic-toxin screens because it was a naturally occurring cardiac glycoside.
Nia stared at the teacup.
Her heart hammered against her ribs.
If she spoke, she would break the cardinal rule.
Maids did not speak to the boss.
They certainly did not interrupt family business.
But she was looking at a dying man, and she knew exactly what was killing him.
Thursday afternoon arrived beneath heavy, oppressive rain that battered the estate windows.
Matteo had deteriorated further.
His skin had become the color of old parchment, pulled taut over his skull. He slipped in and out of consciousness.
Nia pushed her utility cart toward the master suite, gripping its plastic handle until her knuckles turned white.
She had spent the previous 48 hours agonizing over what she had smelled. She had gone home to her tiny, cramped apartment, dug through her late grandmother’s weathered botanical journals, and confirmed her worst suspicion.
Digitalis toxicity.
Foxglove.
It was an old-world poison derived from a beautiful, bell-shaped purple flower. In small, medically synthesized doses, it was used to treat heart failure. In raw, unregulated amounts, stealthily steeped into strong, bitter ginger tea, it was a slow and agonizing death sentence.
It caused extreme nausea, erratic bradycardia, and the telltale visual disturbance known as xanthopsia, a condition in which the victim saw yellow-green halos around objects.
The doctors had been searching for modern synthetic killers. They were looking for mafia staples: cyanide, antifreeze, heavy metals.
They were not looking for a garden flower crushed into an herbal tea blend.
Because digitalis cleared from the bloodstream rapidly or bonded to heart tissue, a standard toxicology screen taken hours after ingestion would not necessarily flag it unless the doctors were specifically testing for digoxin levels.
Nia stopped outside the oak doors.
2 guards stood on either side. They barely looked at her as she pushed her cart inside.
The room felt like a tomb.
Enzo sat slumped in an armchair, staring at the floor with bloodshot eyes. He looked like a man who had not slept in a week.
Matteo lay motionless on the bed. The rhythmic hiss of the oxygen concentrator was the only sign that he was still breathing.
Carlo was there again.
He sat close to the bed holding a fresh cup of tea. He looked incredibly sad.
“He’s not waking up,” Carlo murmured, resting his hand on Matteo’s motionless arm.
“He’ll wake up,” Enzo growled without looking at him. “He’s stubborn. He’ll wake up.”
Nia moved into the corner and pretended to organize fresh linens.
She watched Carlo.
He was careful. Patient.
He played the grieving, devoted cousin perfectly.
Every afternoon, without fail, he brought Matteo his special tea to settle his stomach. Every afternoon, Matteo drank it, desperate for relief, unknowingly swallowing the substance destroying his organs.
If Matteo died, who took over?
Enzo was the muscle, but he was not blood.
Carlo was.
Carlo managed the clean money.
Carlo could inherit the throne, keeping Enzo as a guard dog or quietly disposing of him.
It was a brilliant, quiet coup.
Nia picked up a duster and moved toward the bedside table.
She needed certainty.
She could not risk her life on a hunch.
The silver canister Carlo used for the loose-leaf tea sat there.
Carlo stood.
“I’m going to make a call to Father Thomas. It might be time to have him come by, just in case.”
Enzo’s head snapped upward.
“Don’t you dare call a priest into this house, Carlo. You bring a priest, you’re telling the men he’s dead. I’ll shoot the priest on the front lawn.”
“Enzo, be reasonable.” Carlo sighed. “Look at him. We have to prepare for reality.”
He turned toward the bay windows and pulled out his phone.
Enzo buried his face in his hands.
Nia moved.
She slipped silently to the bedside table.
The silver tea canister sat beside the crystal honey pitcher.
Her hands shook as she removed the lid.
The smell hit immediately.
Strong ginger.
Mint.
And underneath them, the dry, dusty, bitter scent of crushed foxglove leaves.
Nia looked inside.
Among yellow chunks of dried ginger and green tea leaves were tiny coarse flakes of dried purple and grayish-green vegetation.
She snapped the lid closed.
Carlo turned.
“What are you doing?”
The sympathetic tone had vanished.
Nia froze.
Enzo looked up, his dark eyes fixing on her.
“I—I was just dusting the table, sir.”
Carlo approached the bed.
He looked at the canister.
Then at Nia.
His eyes narrowed.
For a fraction of a second, Nia saw the real Carlo.
The mask slipped.
There was no grief in his expression. Only cold, calculating paranoia.
“Dust somewhere else,” he said smoothly as the mask returned. “And don’t touch the boss’s things.”
“Yes, sir.”
Nia retreated to her cart and left.
The moment she reached the hallway, her chest heaved.
She leaned against the cool plaster wall, struggling for air.
She had confirmation.
Carlo was poisoning Matteo Costa directly beneath Enzo’s nose and beneath the noses of 12 top-tier doctors.
Nia could walk away.
It was not her problem.
These were violent, dangerous men. If Matteo died, the world was arguably a better place. He was a criminal. He had ruined lives.
Why should she risk a bullet to save a mafia boss?
As she descended the grand staircase toward the servants’ quarters, however, the thought gnawed at her.
She hated criminals.
But she hated cowards more.
Carlo was killing a man who trusted him, exploiting his vulnerability while pretending to care for him.
It was insidious.
It was pathetic.
There was also a practical consequence. If Matteo died, the entire syndicate could plunge into chaos. A war would break out in the streets, and innocent people could be caught in the crossfire.
Then there was the money.
Matteo was known for his ruthless generosity toward people who proved fiercely loyal.
Nia was broke, drowning in her late mother’s medical debt, surviving on instant noodles and fear.
She stopped at the bottom of the staircase and looked back toward the 3rd floor.
She made her choice.
She was not going to be a ghost today.
By Friday evening, Matteo’s heart rate had fallen to a dangerous 35 beats per minute.
The monitors in his room sounded a persistent, high-pitched alarm as 2 nurses kept on staff for basic life support frantically adjusted his IV fluids.
Nia stood beside her cart in the hallway.
Enzo paced the room like a caged tiger, barking orders into his phone as he tried to get Dr. Keller back to the estate.

“I don’t care if he’s at his daughter’s recital. Put him in a car and get him here, or I’ll burn his practice to the ground.”
He slammed the phone shut.
