And for half a second, as they turned their head, the porch light caught their profile.
Not enough to see a face clearly.
But enough to recognize the way they walked—like they were always in a hurry, like the world owed them room.
My chest went tight, my vision narrowing.
Because I knew that walk. I’d followed it my whole childhood.
And the worst part was this: if I was right, then my mom’s note wasn’t paranoia. It was a warning she didn’t have time to finish.
So why would someone who had a key… still sneak in like a stranger?
Part 4
I didn’t confront Kara right away. Not because I was noble. Because I was terrified.
There’s a special kind of horror in suspecting your own blood. It makes you feel dirty, like you’re betraying them just by thinking it. And yet, every time Kara spoke, my body reacted like it was hearing something false.
On day five, Kara cornered me by the hospital vending machines. The fluorescent lights turned her skin the color of paper.
“Jamie,” she said softly, “the detective asked me about the will.”
My stomach clenched. “Okay.”
She brushed hair behind her ear, nails immaculate. “Mom and Dad never updated it after… you know, after college. It probably still lists us both equally.”
I stared at her. “Why are we talking about this while they’re unconscious?”
Her eyes widened like I’d slapped her. “I’m just being practical. We have to be.”
Practical. Again. Like the most important thing in the room wasn’t my parents fighting to wake up.
Miles came up behind me and Kara’s gaze flicked to him, annoyed, like he was an interruption.
“What did the fire inspector say?” she asked him, too casual.
Miles didn’t blink. “He said someone tampered with the safety system.”
Kara’s smile twitched. “That’s extreme.”
“You know what’s extreme?” My voice shook. “Two CO detectors without batteries. A missing clip history. A vent pipe loosened.”
Kara’s face hardened. “Are you accusing me?”
The question hit the air like a match near gasoline.
I could’ve lied. I could’ve softened it. I could’ve protected the fantasy that she was still my sister.
Instead, I heard myself say, “Where were you, Kara? Really.”
Her jaw clenched. “I told you. A retreat.”
“What’s it called?” Miles asked, calm.
Kara hesitated. Half a second too long. “It’s… small. Private.”
Miles nodded like he was humoring a child. “Show us a receipt.”
Kara’s cheeks flushed. “I don’t have to prove anything to you.”
“You kind of do,” I said, and my own voice scared me.
She stepped closer, lowering her voice. “Do you have any idea what you’re doing? If you point fingers and you’re wrong, you’ll destroy this family.”
The irony almost made me laugh.
Before I could respond, my phone buzzed. A message from an unknown number.
It was a photo.
A screenshot, actually, from a real estate listing.
My parents’ house. Their address. A note beneath it: Great location. Cash buyers ready.
I stared so hard my eyes watered.
Miles leaned in, reading over my shoulder. His expression went still. “Who sent that?”
“I don’t know,” I whispered.
Kara’s eyes landed on the screen. For the first time, her composure cracked. Her lips parted like she was about to say something and then thought better of it.
That tiny slip told me more than any confession could.
Later, while Kara went to get “air,” Miles drove to the hardware store listed on the receipt. He came back an hour later with a look I’d never seen on him before—like he’d stepped too close to something rotten.
“The cashier remembered her,” he said.
My throat tightened. “Kara?”
He nodded. “She bought the flue kit and the batteries. She joked about ‘finally making the old place safe.’”
Safe.
I tasted bile.
That same evening, I walked past a quiet hallway near the elevators and heard voices.
Kara’s voice.
And a man’s voice I recognized from family dinners—Owen, her fiancé. He always wore expensive shoes and smiled like he was selling something.
“She’s getting suspicious,” Kara hissed.
Owen’s voice was low, impatient. “She can be suspicious. It doesn’t matter if we control the paperwork. If they don’t wake up, the house gets tied up in probate and—”
Kara snapped, “Don’t say that here!”
Owen sighed. “Kara, we’re in too deep. Just stick to the story.”
My blood went cold.
I backed away silently, heart hammering so hard I felt it in my throat.
My sister wasn’t just worried about my parents.
She was worried about timing.
And as I stood there shaking, my phone buzzed again—this time with a call from the detective.
“Jamie,” he said, voice serious, “we ran Kara’s alibi. The retreat photos she gave us? They’re stock images pulled from the internet.”
My vision blurred.
Because if she lied about where she was… then what else had she been lying about this whole time?
Part 5
When my dad finally woke up, it wasn’t dramatic. No movie moment. No sudden sit-up with a gasp.
His eyes just opened slowly, like he was swimming up from a deep, ugly lake.
I was the first person he saw. His gaze drifted to my face, unfocused, then sharpened with effort.
“Jamie?” His voice was cracked, like paper tearing.
I grabbed his hand so gently I was afraid of hurting him. “I’m here. You’re okay. You’re in the hospital.”
He blinked, slow. His eyes shifted toward the machines, the tubes. Confusion flickered, then fear.
“What happened?” he rasped.
I swallowed hard. “You were exposed to carbon monoxide. Both of you.”
His brow furrowed. “The alarms…”
My stomach clenched. “They didn’t go off.”
My dad stared at the ceiling, and for a moment I saw something in his face that wasn’t just weakness. It was realization. Like a puzzle piece clicking into place.
Then he whispered, barely audible, “Kara.”
My skin went cold. “What?”
His eyes slid to mine. “She was here,” he said, each word dragging. “Night before. Said… thermostat was acting up.”
Miles stepped closer, his voice gentle. “Did she change anything?”
My dad’s eyelids fluttered. “I heard… a click. Hallway. Then the air felt… thick. Like… breathing through a towel.”
Tears stung my eyes. “Did you see her take anything?”
He swallowed, throat bobbing painfully. “I saw her… holding something. White. Like… the alarm.”
My chest tightened so hard it hurt.
There it was. Not proof in a file. Not a log. Not a grainy clip.
My father’s voice, saying my sister’s name like it tasted like ash.
We didn’t tell him everything right then. He was too weak. The doctor warned us stress could set him back.
But the detective didn’t waste time.
That afternoon, Miles handed over the restored doorbell clip, the receipt, and the thermostat account details. The detective’s face didn’t change much—he’d probably seen a thousand versions of betrayal—but his eyes sharpened.
“Thermostat logs will be key,” he said.
Miles nodded. “I can pull them. If she used her phone, it’ll show device access.”
We sat in the hospital café with burnt coffee and stale muffins while Miles worked. The café smelled like toasted bread and disinfectant, like someone tried to make comfort out of chemicals.
Miles’ fingers flew across his laptop.
Then he stopped.
“Jamie,” he said quietly.
