Chapter 4 - The Key in the Lock

The adhesive on the security camera mount was still tacky, smelling faintly of industrial glue. Mark stared at the small, black lens screwed into the corner of his apartment’s front door, feeling a strange mixture of absurdity and relief. It was a ridiculous expense, really—forty dollars a month for a monitoring service he’d insisted on installing the moment Taylor’s text message had pinged his phone three days ago.
*“Evelyn is old. Her mind is going. You’re scaring Lily for no reason.”*
Mark had stared at those words, the screen of his phone glowing in the dark kitchen. He had told himself, It makes sense. It was the most logical explanation. Evelyn, with her wandering eyes and her habit of forgetting to pay bills, was a liability. Taylor, with her frantic texts and her insistence that Lily was "imagining things," was just trying to protect her mother.
So, Mark had bought the camera. He had told Lily, "We're just watching out for the house, sweetie. Nothing bad is going to happen."
Lily had nodded, her large eyes wide, but Mark had seen the flicker of a shadow behind her. It had been gone in a second, he told himself. Just a trick of the light.
The days that followed were maddeningly quiet. The camera feed was a digital ghost town. A cat scratching at a fire hydrant outside. A neighbor walking a dog. Nothing. No intruders. No Taylor. The silence of the apartment began to settle over Mark like a heavy quilt, suffocating his paranoia. The doubt took root in his mind like a weed.
Maybe Taylor was right. Maybe he was projecting. Maybe Lily was safe. Maybe he was just a divorced father with too much time on his hands and a desperate need to control the uncontrollable.
But the night was different.
Mark sat on the edge of his bed, the laptop open on his lap. It was 2:14 AM. The feed on the screen was grainy, the night vision staticky, but he was watching it anyway. He had a habit of checking the app every hour, a ritual born of fear that he couldn't quite shake.
At 2:19 AM, a red box appeared in the bottom left corner of the screen.
Mark’s breath hitched in his throat. A car door slammed outside. The sound was muffled through the glass, but it was unmistakable.
He stared at the feed. The front door was visible through the peephole. The hallway light was off, casting the space in a bruised purple shadow.
A figure stepped into view.
It was Taylor.
She was wearing a heavy coat, her hair pulled back in a messy bun. She didn't knock. She just stood there, motionless, her back pressed against the doorframe. Mark watched, his heart hammering against his ribs like a trapped bird. She stood there for five minutes. Ten minutes.
He stood up, his legs stiff. He grabbed his car keys, his hand trembling as he unlocked the deadbolt. He needed to confront her. He needed to know why she was here, why she wasn't answering her phone, why she was standing outside his door in the middle of the night like a specter.
He walked to the door, his hand on the knob. He took a breath, ready to scream her name.
*Click.*
The sound of the deadbolt sliding home echoed through the apartment.
Mark froze. He stared at the lock. He hadn't locked it. He had just unlocked it to go out. He spun around, his pulse racing. She must have unlocked it from the inside, he thought. She must have heard me.
He reached for the handle again, turning it slowly. The door swung open.
"Taylor?" he whispered.
The hallway was empty.
Panic, cold and sharp, spiked in his veins. He rushed out into the hallway, his bare feet slapping against the floorboards. He looked left. He looked right. Nothing. The elevator doors were closed. The stairwell was dark.
He stumbled back into the apartment and slammed the door, locking it twice, then three times. He pressed his ear against the wood, listening for any movement. Nothing. Just the hum of the refrigerator and the sound of his own ragged breathing.
He fell onto the couch, burying his face in his hands. He had been so sure. He had seen her. But now, he was alone in the dark, questioning his own sanity.
Morning light filtered through the blinds, casting long, gray strips across the floor. Mark woke with a crick in his neck, the events of the night feeling like a fever dream.
Lily was sitting at the small kitchen table, coloring a picture with a box of crayons. She looked like a normal child, her hair combed, her clothes clean.
"Morning, Daddy," she said, not looking up.
"Morning, Lil," Mark said, his voice hoarse. He walked to the fridge to get coffee, his mind racing. He needed to call the police. He needed to tell them she was trespassing. He needed to—
"Mommy came in last night," Lily said suddenly.
Mark turned around, the coffee mug halfway to his lips. "What?"
"Before you went to bed," Lily said, her crayon moving in a slow, deliberate circle. "She came in and kissed me goodnight. She said it was our secret."
Mark felt the blood drain from his face. "Lily, you're lying. Mommy wasn't here. I saw her leave. I saw her leave the car."
"She was here," Lily insisted, her voice small but firm. "She whispered in my ear. She said, 'Don't tell Daddy. It's our secret.' Then she left."
Mark’s hands were shaking so badly he almost dropped the mug. He rushed to the laptop, his fingers fumbling over the keyboard as he pulled up the security footage from last night.
2:19 AM. The figure in the coat. Taylor.
He scrubbed through the timeline. She stood there. She waited. She left.
Mark’s heart stopped. He pressed play.
The screen showed the hallway. The door was visible. The lock was engaged. It hadn't been touched.
Taylor stood at the door for ten minutes. She stared at the peephole. She didn't knock. She didn't ring the bell.
Then, she turned and walked away.
Mark watched in horror as the footage played out. Taylor was nowhere near the apartment. She was gone. But if she wasn't here, if the footage was real... then who was in the apartment with Lily?
He watched the screen, the grainy night vision making everything look like shadows.
Then, he saw it.
A shadow moved past the camera lens. It wasn't Taylor. It was a dark, amorphous shape that slithered across the living room floor. It moved fast, too fast to be a cat. It stopped near Lily’s bedroom door.
The feed glitched, a burst of static obscuring the view for a split second.
When the image cleared, the living room was empty. The shadow was gone.
But Lily was still sitting at the table, coloring. And she was smiling. A small, knowing smile.

Mark looked at the timestamp on the screen. 2:35 AM.
Taylor had left at 2:29 AM.
