PART 1

My bedroom was pitch black except for the cold, blue numbers glowing on the digital clock. I almost let the ringtone play a second time before I reached out and saw Chloe’s name illuminating the screen.
She was eight years old, a sweet kid who still drew bright pink butterflies on my birthday cards and made a point to call me every single Sunday. My late wife, Martha, had once told her that grandfathers needed checking on, and the little girl had taken that instruction straight to heart.
I pressed the green button and lifted the phone to my ear, hearing her strange, raspy breathing before she even managed to speak.
“Grandpa?” she whispered, her voice sounding paper-thin and entirely wrong. “I feel so hot.”
I knocked my reading glasses off the wooden nightstand in a rush to sit up in the dark. “Chloe, sweetie, where are you right now?”
“I am at home,” she replied softly.
“Where is your mother? Where is Patrick?” I asked, my chest tightening.
Her prolonged silence frightened me far more than any panicked answer she could have given.
“They left,” she finally murmured.
Patrick is my son, and his wife, Samantha, had spent all week telling the entire family that they were taking Chloe’s ten-year-old brother, Wyatt, to Orlando for a grand birthday celebration. Chloe supposedly had a minor sniffle and was going to spend two quiet nights over at Samantha’s sister’s house in Ohio.
That was the official story everyone in the family had been told.
Yet Chloe was not with any aunt, but instead sitting all alone in that dark house in the middle of the night, barely able to keep her trembling voice above a whisper.
I pulled on a pair of denim jeans with one hand while keeping the mobile phone pinned tightly against my ear with the other. “Chloe, are the front doors locked?”
“I do not know,” she whimpered gently. “My head hurts so bad, Grandpa, but the kitchen light is on.”
“You stay right on the line with me, okay?” I pleaded as I grabbed my car keys.
“I am really scared,” she said.
“I am coming to get you right now,” I promised her.
Patrick’s quiet residential neighborhood in Columbus usually took about fourteen minutes to reach from my place. I vividly remember the car dashboard displaying 2:06 a.m. when my tires squealed onto his quiet street, and I remember gripping the leather steering wheel so hard my knuckles turned white. Most of all, I remember muttering under my breath to Martha, almost as if my passed-away wife were sitting right there in the passenger seat beside me.
The asphalt driveway was completely empty when I pulled up to the curb.
There was no family minivan, no packed luggage resting by the door, and no indication that two adults had merely stepped out for a quick errand and intended to return shortly.
I retrieved the spare emergency key hidden inside a fake rock near the porch bushes and pushed my way inside the quiet house.
A heavy, sweet chemical odor hit my nose the moment I crossed the threshold, smelling like a mixture of cherry cough syrup, warm unventilated air, and something medicinal hanging in the hallway.
“Chloe!” I called out into the dark space.
The bright fluorescent kitchen light was shining bright just as she had described. A half-empty glass of tap water rested on the laminate counter near the sink, and one of Wyatt’s white running shoes lay on its side in the middle of the carpeted hall.
Then my eyes landed on Chloe.
She was curled up tightly on the cold hardwood floor in her patterned pink pajamas, with one flushed cheek pressed flat against the wooden boards. Damp strands of blonde hair clung tightly to her forehead, her skin was a deep burning red, and her tiny fingers were hooked weakly into her chest as if she had tried to crawl toward the front door and collapsed.
“Grandpa…” she breathed out quietly.
I dropped down onto my knees beside her and placed my bare palm against her clammy forehead.
She was burning up with a terrifyingly high fever.
I quickly dialed 911 on my cell phone and gathered her small body up against my chest. Her heavy head sagged uselessly against my shoulder in a limp way that made my stomach turn completely upside down.
While the emergency dispatcher asked me for the exact street address, I noticed a bright orange plastic prescription bottle standing right on the white kitchen counter.
The name printed on the white pharmacy label was certainly not Chloe’s.
In fact, the strong medication listed on the bottle was not meant to be prescribed to a young child under any circumstances.
Right beside the bottle sat Patrick’s metal keyring and a single sheet of lined paper folded in half.
I snatched up the handwritten note and unfolded it with my free hand.
“Dad, please do not overreact about this,” the scrawled handwriting read. “Chloe always gets completely dramatic whenever she comes down with a fever. We gave her a small dose of something strong to help her sleep through the night so she would not ruin Wyatt’s birthday weekend like she usually does. We will be back on Sunday evening, so please do not bother calling anyone or causing a scene.”
I read through those cold lines twice because my horrified mind simply refused to process that my own son had written those words.
Then my eyes caught the terrifying final sentence written at the bottom of the page.
“And whatever she tries to tell you tonight, do not believe a single word she says about the hallway closet.”
I completely stopped breathing right then and there.
The white doors of the hallway closet were positioned roughly ten feet away from where I stood in the kitchen.
Chloe’s tiny, feverish fingers suddenly gripped the fabric of my flannel shirt with surprising force.
From right behind that hollow wooden closet door, a single soft knock echoed into the room.
The female dispatcher was still talking urgently into my earpiece, but every other sound in the house seemed to dissolve into complete silence.
A second faint knock followed immediately after the first one, sounding even weaker than before.
Then came the distinct sound of something dragging against the floorboards inside.
