A wealthy forty-year-old had already spent quite a lot…
“I was startled.”
“By what?”
She glanced in my direction. For a brief second, an emotion flickered between us: terror. Then she quickly turned her gaze away.
“I need to bring these up to the boys’ rooms,” she said, turning on her heel.
“Mrs. Harper.”
She paused. Vincent’s tone had shifted—it wasn’t loud, which somehow made it far more menacing. “Don’t go anywhere.”
Slowly, she rotated back to face him. Vincent took a step toward her. “How long have you noticed that odor?”
“I’m not sure what you mean.”
I glanced back at the air vent. The faint floral trace lingered in the air—sweet, artificial, smelling somewhat like heavy laundry soap combined with medicinal undertones. Beneath that, however, lay a dry, bitter hint. It was faint enough that I might have ignored it entirely, except for my years of experience looking after children with severe environmental allergies.
Stepping closer, I asked, “Do the boys frequently complain about headaches?”
Vincent stared at me. “Yes.”
“Both of them?”
“Yes.”
“Do those headaches get worse in the mornings?”
He hesitated. “Yes.”
I looked toward the children’s bedrooms. “Do they sleep in here every single night?”
“Naturally.”
“And do they feel better whenever they leave this house?”
Vincent’s expression froze completely. “At times.”
“What do you mean by at times?”
“When they spent a week visiting my sister last summer, Lucas actually gained nearly two pounds.”
My chest tightened. “What about Leo?”
“His appetite came back.”
“Did their physical weakness get better too?”
Vincent gave a slow nod. “For a little while.”
I turned my eyes back to the vent. “Then why on earth did you bring them back here?”
“Because this is their home.” His voice cracked slightly on the final word.
I turned back to him. For the first time since my arrival, I caught a glimpse of something beneath Vincent Moretti’s immense fortune—not power, not anger, but sheer panic. It was the distinct terror of watching your kids fade away bit by bit, despite having enough wealth to buy almost anything except a solution.
“I genuinely thought they were just grieving,” he murmured.
I stayed silent.
“Ever since Isabella passed away, they’ve been different,” he continued, looking toward the boys’ hallway. “Everyone assured me that children process trauma differently. Then the exhaustion started, followed by the rapid weight loss, and finally, the parade of doctors.” His jaw clenched. “I paid a fortune to get answers.”
“And not a single person checked the house itself?”
“They tested the water supply.”
“What about the air?”
“Yes.”
“More than once?”
“Three times.”
“Handled by whom?”
“Independent environmental consulting firms.”
I eyed the vent again. “Did anyone test the bedrooms specifically?”
Vincent offered no reply. That silence answered my question entirely. I shifted my gaze to Mrs. Harper. “Who handles the cleaning in these rooms?”
She hesitated. “I do.”
“Anyone else?”
“No.”
“What supplies do you use?”
She listed several common brands, most of which I recognized. Then she mentioned a specific room deodorizer used throughout the upper level. My interest spiked. “What’s in that spray?”
“It’s cleared by Mr. Moretti’s estate management team.”
“That wasn’t my question.”
Mrs. Harper frowned. “I honestly don’t know.”
“Who orders it then?”
“Mr. Blake’s office.”
A heavy silence fell over the room. Vincent stared at her. “Dr. Blake orders our household air fresheners?”
Color drained completely from Mrs. Harper’s face. “I assumed you were aware.”
Vincent’s gaze turned ice-cold. “I wasn’t.”
Before anyone could say another word, a weak voice drifted from the nearby bedroom. “Dad?”
Vincent rushed to open the door. Lucas was sitting up on the side of his bed, looking far too fragile for a seven-year-old. His pajamas hung loosely off his shoulders, and dark, hollow circles framed his eyes. Leo lay motionless beneath the covers, looking even paler.
“What’s the matter?” Vincent asked.
Lucas rubbed his temples. “The room has that weird smell again.”
Vincent locked up. I stepped inside the bedroom. “What does it smell like to you?”
Lucas looked up at me. “Flowers.”
Leo chimed in with a whisper from the other bed, “Bad flowers.”
I crouched down next to Lucas. “Does it make your head hurt?”
He nodded slowly. “Sometimes.”
“Do you feel wiped out after staying in here?”
Another nod. I looked up at Vincent, whose face had completely drained of color.
“Boys,” I said softly, “when you stayed with Aunt Sofia last summer, did you feel better?”
Lucas nodded immediately, while Leo whispered, “We were able to run around again.”
Vincent closed his eyes. Hearing that hurt him far more than any negative medical report ever could. He sat down on the edge of Lucas’s bed and gently stroked his son’s hair. “You’ll be able to run again soon, I promise.”
Lucas looked up at him doubtfully. “Do you promise?”
Vincent’s eyes glistened. “I promise.”
I stood back up. “We need to get them out of these rooms immediately.”
Vincent looked at me in shock. “Where?”
“Somewhere away from the main house.”
“Right now?”
“Right now.”
He didn’t waste time arguing. Within twenty minutes, Lucas and Leo were settled in the back of Vincent’s SUV with Mrs. Harper beside them, and I climbed in as well. Vincent drove himself—no security detail, no chauffeurs, no phone calls—just a father rushing his children away from the very house that had consumed eighteen months of their childhood.
We headed to a small guest cottage situated at the far edge of the estate. It had sat vacant for months, featuring no central ventilation system, no chemical room sprays, and no new furniture—just aged wooden floors, simple beds, and windows that opened straight out to the garden.
The boys laid down, and within an hour, Leo drifted off to sleep while Lucas quietly flipped through a comic book. I sat down beside him. “Do you feel any different?”
He gave a small nod. “My head stopped hurting.”
Vincent stood quietly in the doorway, having heard every word. His eyes closed for a brief moment.
He didn’t sleep that night, and neither did I. By 2:17 a.m., I found him sitting by himself at the kitchen table with an open medical file spread out before him.
“What are you working on?” I asked.
“Going through everything one more time.”
“You’ve probably read those reports a hundred times already.”
“Maybe I missed a detail.”
“You didn’t.”
He looked up at me. “How can you be so sure?”
“Because you’ve spent all this time searching for a medical illness.”
He waited for me to continue. “Perhaps we should be looking for an environmental exposure instead.”
He leaned back in his chair. “You honestly believe something in this house is poisoning them?”
“I believe we have more than enough clues to launch a real investigation.”
“Clues like what?”
“They feel instantly better when they leave the premises. Their symptoms flare up exclusively in specific rooms. There’s an odd chemical odor coming through the vents. Someone else is controlling the products used upstairs, and your estate manager acted like she recognized that scent.”
Vincent stared hard at me. “Could it really be that straightforward?”
“No.”
He frowned. “Why not?”
“Because if it were that simple, three separate environmental firms and eleven months of medical specialists would have caught it.”
He glanced toward the dark window. “Then someone must have missed something.”
“Or someone purposely looked in all the wrong places.”
The silence stretched out before Vincent spoke in a tone so low I barely caught it. “Isabella used to complain about that exact smell.”
I looked straight at him. “When?”
“Roughly six months prior to her passing.”
My stomach churned. “What did she say about it?”
“She mentioned that the upstairs hallway smelled odd.”
“Did she fall ill?”
“Not the way the boys did.” He rubbed his face tiredly. “She dealt with occasional headaches and nausea, but she always blamed it on stress.”
“Did she ever bring up the ventilation system?”
“Only that she hated the lingering scent in the hallway.”
“Why didn’t you mention that to the doctors?”
“I forgot all about it.”
I stared at him in disbelief. “You forgot?”
His eyes met mine with quiet pain. “You think I don’t despise myself for that?”
I immediately regretted my harsh tone. He looked completely exhausted. “After the accident, sleep stopped happening for me. I couldn’t process anything clearly. Then the boys fell ill, and every physician kept grilling us about diet, genetics, infections, or neurological conditions…” His voice broke. “Not a single person bothered to ask what Isabella might have noticed.”
I sat down across from him. “In that case, we start investigating the house tomorrow morning.”
He nodded in agreement. But before we could say another word, his cell phone buzzed. Vincent checked the caller ID—Dr. Harrison Blake.
He answered sharply, “What is it?”
The doctor’s voice was barely audible from where I sat. Vincent’s expression shifted instantly. “What do you mean you heard about it?”
A brief pause followed. Then: “Who told you?”
Another pause. Vincent stood up abruptly. “No. You are not coming over here tonight.” He hung up the phone abruptly.
“What just happened?” I asked.
He didn’t reply right away, simply staring at me. “Dr. Blake already knows the boys aren’t sleeping in their rooms.”
“How on earth would he know that?”
“I have no idea.”
His phone rang a second time. This time, it wasn’t Dr. Blake—it was the estate’s security automated system. Vincent answered on speaker. “Give me a status report.”
A guard’s voice spoke rapidly on the other end. Vincent’s face hardened. “Which camera zone?” He listened closely. “Don’t touch anything until we get there.” He disconnected the call.
“What’s going on?”
“There was unauthorized movement near the boys’ bedrooms.”
My skin prickled with unease. “Someone is inside the mansion right now?”
“Security reports nobody forced open any exterior doors.”
“Then how did they spot movement?”
Vincent was already heading toward the cottage door, and I followed right behind him. Across the dark lawn, the massive mansion stood silent, its windows pitch black—except for one. The light in the upstairs hallway was switched on.
Vincent came to a dead stop. “That hallway light was off.”
We stared at the house in silence. A second later, that light clicked off, and another one flickered on inside Lucas’s bedroom.
Vincent broke into a run, and I kept pace right behind him. The estate security team converged on the front doors seconds later, unlocking them so everyone could rush inside together.
The main hallway was completely deserted. Lucas’s bedroom door stood closed. Vincent shoved it open—the room was empty. The bed remained untouched, the curtains hung still, and the windows were securely locked from the inside.
Then I spotted it resting on Lucas’s pillow: a small white envelope.
Vincent stopped beside me. There was no recipient name, no postage stamp, and no handwritten address—just a single sentence printed in stark black ink:
STOP LOOKING AT THE AIR.
For several moments, nobody dared to breathe. Then Vincent reached out toward the pillow.
“Don’t touch it,” I warned.
He froze his hand. I pointed at the envelope. “Don’t alter a thing.”
A security officer quickly stepped forward to photograph it. Vincent’s breathing grew heavy. Someone had infiltrated his private residence, left a warning behind, and clearly knew precisely what we were uncovering.
Yet the most unsettling part wasn’t the note itself—it was what I noticed tucked just beneath the pillow. A tiny, glinting silver object.
Using a gloved hand, I carefully lifted the corner of the pillow. Hidden underneath was a small metal disk, roughly the size of a coin. I stared down at it with a frown.
Vincent looked utterly confused. “What on earth is that?”
“I have no idea yet.” I inspected the surface closely. A symbol was etched right into the metal: a circle enclosing two parallel lines, with the number 17 stamped directly beneath them.
My heart began to race.
“Why does that number matter?” Vincent asked.
I looked up at him. “I intend to find out.”
Then a familiar sensory detail hit me. The smell. It wasn’t drifting from the air vent anymore—it was radiating directly off the silver disk.
I instinctively stepped backward. “Vincent…”
“What is it?”
“The odor traveled with this object.”
He stared at me blankly. For the first time, an unthinkable possibility settled in: perhaps the central ventilation system wasn’t the primary source after all. Maybe it was merely transporting something else from an entirely different location—something hidden away deliberately inside the walls.
Vincent glanced out toward the dark hallway. “How many total rooms are on this upper floor?”
“Seventeen,” Mrs. Harper whispered from the doorway.
I turned my attention to her. She looked utterly terrified once more. “Why did you say that number?”
She stared fixedly at the silver disk on the bed. “Because…” Her voice shook. “I’ve seen that exact symbol before.”
“Where?”
She looked between Vincent and me. “Inside Isabella’s old room.”
The chill in the hallway seemed to drop another ten degrees.
“Where is her room located?” I demanded.
No one answered immediately. Finally, Vincent spoke up. “At the far end of the east wing.”
“Is it still preserved the way she left it?”
His jaw tightened. “Yes.”
“Then that’s where we’re heading.”
We walked through the cavernous mansion in total silence, every footstep echoing heavily. The east wing had remained sealed off since Isabella’s death. A thick layer of dust blanketed the furniture, and her personal belongings sat precisely where she had left them: a violin leaning against the wall, a half-finished canvas resting near the window, and a framed photograph on the bedside table showing Isabella smiling with the boys. Lucas was missing a front tooth in the picture, and Leo had both arms wrapped tightly around his mother’s waist.
Vincent stopped dead in the doorway, the pain clearly visible across his face, and quickly looked away. “I haven’t stepped foot in here since the funeral.”
I walked straight toward the bedside table. No silver disk rested there, nor any threatening envelope—nothing out of the ordinary at all. Then my eyes drifted over to the oil painting on the wall. It depicted the upstairs hallway where the boys’ bedrooms were situated. But in the painted scene, a particular piece of furniture appeared that no longer existed in reality: a small decorative cabinet positioned right beneath the ventilation grate.
I looked from the painting to the bare wall, then back to the painting again.
“Vincent.”
“What?”
“Was there ever a cabinet built into this wall in the hallway?”
He frowned, struggling to recall. “I honestly don’t remember.”
Mrs. Harper, however, did. “Yes, there was.”
All eyes swung toward her. “It was removed about three years ago.”
“Who took it down?” I pressed.
She hesitated nervously. “Dr. Blake.”
Vincent stared at her incredulously. “Why wasn’t I ever informed about this?”
Mrs. Harper’s eyes welled up with tears. “I assumed you already knew.”
I walked over to that exact section of the wall. A faint rectangular outline remained visible beneath the wallpaper. Running my fingertips along the edge, I felt a slight ridge—a concealed seam.
I pressed down hard. Nothing happened. I pressed again.
A soft click echoed from inside the drywall.
Vincent stepped forward eagerly. “What did you find?”
I looked back at him. “I think there’s a hidden compartment right here.”
He watched as the panel slowly pushed inward, revealing a narrow cavity built into the architecture. Tucked inside that dark space sat a heavy black metal box.
Vincent reached in and pulled it out. There were no padlocks and no keyholes—just another silver disk affixed to the lid. This one bore a different number: 18.
Vincent looked at me grimly. “Claire…”
I stared down at the box. “Don’t open it just yet.”
“Why not?”
“Because whoever concealed this already knows we’re tearing the house apart.” I pointed back toward the corridor. “And if they deliberately left it for us to find…” I swallowed hard. “…then maybe we were meant to open it all along.”
Before Vincent could respond, all the overhead lights cut out instantly.
The entire mansion plunged into absolute darkness. Somewhere down on the ground floor, a security alarm began wailing at top volume. Then came the sound of running footsteps echoing through the halls—someone was still inside the house, and this time, they weren’t even bothering to hide.
