Chapter 3 - The Powder in the Wallpaper
By 2:00 AM, the Duca estate had been transformed into a fortress under siege.
Four black SUVs belonging to Lorenzo’s private forensic medical team—led by Dr. Marcus Cole, a brilliant, fiercely loyal toxicologist who had served the Duca family for two decades—had pulled up to the front entrance.
The entire third floor was locked down. Mobile lab equipment, mass spectrometers, and chemical testing kits were carried upstairs in heavy silver cases.
In the spacious, luxurious guest suite across the hall, Elena sat on the edge of a velvet sofa, watching Leo play quietly on a thick Persian rug. The toddler was blissfully unaware of the high-stakes drama unfolding outside her door, busy building a tall tower out of polished mahogany wooden blocks.
The door opened softly, and Lorenzo stepped inside.
He had removed his jacket and gun holster, wearing only a dark grey dress shirt with the sleeves rolled up to his forearms. He looked exhausted, the lines around his sharp eyes deeper than before, but there was a dangerous, razor-sharp focus in his demeanor.
"Dr. Cole has completed the preliminary field analysis of the water glass," Lorenzo said, standing near the fireplace.
Elena stood up nervously, her hands clutching the fabric of her skirt. "And... what did he find, sir?"
Lorenzo’s face turned as hard as flint.
"Heavy metal toxicity," Lorenzo revealed, his voice dangerously quiet. "Specifically, a high concentration of thallium sulfate mixed with microscopic lead particles. Thallium is odorless, tasteless, and completely soluble in water. In small, continuous doses over three years, it mimics the exact symptoms of a severe autoimmune disease—extreme stomach pain, muscle wasting, neurological impairment, and chronic organ failure."
Elena gasped, clutching her hand to her mouth. "Monstrous... Someone was poisoning a six-year-old child?!"
"It gets worse," Lorenzo said, his dark eyes flashing with a terrifying, murderous fury. "Thallium alone would have been detected in a standard toxicology screen if any of the hospital doctors had thought to run one. But the perpetrator mixed it with heavy doses of synthetic lavender oil and lead dust. The lead masked the thallium in standard blood work, while the synthetic lavender mist acted as a respiratory irritant, ensuring he inhaled toxic particles directly into his lungs every night while he slept."
Elena felt sick to her stomach. "Who could do such a thing? The doctors? The nurses?"
"The water carboys were delivered by a specialized medical supply company owned by a subsidiary of the Moretti cartel," Lorenzo spat, his fist clenching so tightly his knuckles popped like gunshots. "Our rival family in New York. They couldn't kill me behind these walls... so they decided to destroy me from the inside out, by slowly draining the life from my only child."
Lorenzo walked over to the rug where Leo was playing. He slowly dropped down to one knee, bringing his towering frame down to the toddler's level.
Leo looked up from her block tower, offering him a small, cheerful smile. "Big man sit?"
"Yes, big man sit," Lorenzo said softly, his harsh face softening by a fraction. "Little girl... Dr. Cole tested the water because you pointed at it. But he says there are other things in that room that are making my boy sick. Will you help me find them?"
Leo blinked her big brown eyes. She set her wooden block down, reached out her chubby hand, and grabbed Lorenzo’s long index finger.
"Help sick boy," Leo said firmly. "He got Captain. Need help."
Ten minutes later, the door to Lucas’s room opened again.
Dr. Cole and three lab technicians in full hazmat suits stood around the room, taking air samples and scanning surfaces with ultraviolet lights. Lucas was resting on his bed, looking noticeably better now that the lavender diffuser had been removed and fresh outdoor air was being pumped into the room through an industrial filtration unit.
Lorenzo walked into the room, holding Leo on his hip, with Elena following closely behind.
"Dr. Cole," Lorenzo called out. "Progress?"
Dr. Cole, a middle-aged man with sharp grey hair and wire-rimmed glasses, shook his head solemnly. "We've confiscated all the water and the diffuser oil, Don Lorenzo. But the ambient chemical sensors in this room are still picking up trace toxicity in the air. It's subtle, but it's here. Something in the very infrastructure of this room is continuing to contaminate the air."
"What about the paint? The carpet?" Lorenzo demanded.
"We scrubbed the carpets and tested the paint samples," Dr. Cole sighed, adjusting his glasses. "Negative. Whatever it is, it's disguised extraordinarily well."
Leo, sitting comfortably in Lorenzo’s powerful arms, suddenly wiggled her little legs. "Down, big man. Want down."
Lorenzo gently set her feet onto the hardwood floor.
Leo didn't hesitate. She toddled straight past the hazmat technicians, past the medical monitors, and walked directly toward the far wall of the room.
The wall was covered in a gorgeous, expensive antique wallpaper—a vintage Italian design featuring intricate gold leaves and deep emerald-green vines woven across a cream background. It had been installed four years ago, shortly before Lucas’s mother had passed away.
Leo stopped three inches from the wall. She tilted her head back, her brown curls tumbling over her shoulders, and stared at the dark green vines.
She reached out a chubby finger, touching a section of the green pattern near the baseboard where the paper met the wood.
"Pretty green," Leo murmured softly. Then, she rubbed her small finger against the green vine and brought her hand up to her face.
"Leo, don't touch!" Elena called out in alarm, stepping forward.
"Wait!" Dr. Cole shouted, his eyes widening in sudden, absolute horror as he saw what the child was doing. "Don't let her touch that!"
Lorenzo reacted with blinding speed. He lunged forward, grabbing Leo by her waist and lifting her away from the wall, while Dr. Cole rushed over with an ultraviolet scanner and a chemical swab.
"What is it, Cole?!" Lorenzo barked, holding Leo securely against his chest.
Dr. Cole pressed the UV scanner against the emerald-green wallpaper. Under the intense blue light, the dark green vines didn't reflect normal light—they glowed a sickly, fluorescent yellow-green.
Dr. Cole’s hands shook violently as he dropped the swab into a test tube of chemical reagent. The clear liquid instantly turned a dark, murky purple.
"My God..." Dr. Cole whispered, his face draining of all color. "Scheele’s Green..."
Lorenzo’s eyes narrowed into slits of deadly rage. "Speak plain English, Marcus."
"It's an 19th-century copper-arsenite pigment, Don Lorenzo!" Dr. Cole gasped, backing away from the wall as if it were a venomous snake. "It was banned over a hundred years ago! When copper arsenite pigment is exposed to high humidity—like the steam from that lavender humidifier sitting in the corner—it reacts with mold spores in the paper glue and releases toxic arsine gas directly into the air!"
The entire room fell into an appalled, breathless silence.
Arsine gas. A colorless, practically odorless chemical weapon that slowly destroyed red blood cells, causing severe abdominal cramps, kidney failure, and eventual death.
Every single night for three years, Lucas had been sleeping in a room where the very walls were breathing lethal arsenic gas into his lungs, while his water was laced with thallium, and his air was thick with lead.
It wasn't a medical mystery. It was a meticulous, torturous execution chamber built by an invisible hand inside the Duca family's ultimate fortress.
Lorenzo stood frozen in the middle of the room.
He looked at the emerald-green wallpaper, then down at the three-year-old girl in his arms, who was looking at her fingers in confusion.
"She saw the dust flaking off the green vine," Dr. Cole whispered in absolute awe, looking at Leo as if she were a miracle sent from heaven. "The humidity from the humidifier was making the arsenic pigment disintegrate into tiny particles at the baseboard. An adult couldn't see it without a magnifying glass... but her eyes were right at eye level with it."
Lorenzo felt a tear—a single, burning tear—break through his three-year composure, slipping down his scarred cheek.
May you like
He tightened his arms around Leo, pressing a soft, deep kiss into her brown curls.
"You saved him," Lorenzo whispered, his voice cracking with an unbearable wave of emotion as he looked over at his son's bed. "Little girl... you saved my boy."
