Our new nanny was a godsend, claiming she loved our twins like her own. I checked the nursery cam during lunch and FROZE. She wasn’t playing with them. She was whispering into a hidden earpiece while facing the crib. I cranked the volume, my stomach churning. She laughed coldly. The audio feed caught three distinct words that stopped my heart cold.

— Eliminate the witnesses!

My phone slipped from my sweaty palm and clattered onto the dashboard of my work van. I scrambled to pick it up, praying I had misheard. The screen was small and cracked, but the image was clear enough. Nicole was standing over the cribs, her posture rigid and menacing.

I didn’t wait to hear another word. I threw the van into reverse, the tires screeching against the customer’s paved driveway. My toolbox slid across the metal floor in the back with a deafening crash. I didn’t care about the noise or the fact that I hadn’t billed the client yet.

The only thing that mattered was getting home to the twins. The drive was usually twenty minutes, but I needed to make it in ten. I merged onto the highway without looking, cutting off a sedan that honked aggressively. I gripped the steering wheel so hard my knuckles turned white.

My mind raced through every interaction we had with Nicole. She had been perfect during the interview. She had excellent references and a warm smile. Jennifer and I had felt so lucky to find her after months of searching. Now I felt like the world’s biggest idiot for trusting a stranger with our children.

Traffic on the I-95 was starting to build up. I cursed loud and hard, slamming my hand against the horn. The heat in the van was stifling, smelling of old copper and refrigerant oil. I needed to focus, but the image of her standing over the cribs burned in my retina.

I had to secure the site before I left, even in my panic. It was pure muscle memory taking over.

I grabbed the manifold gauges hooked up to the condenser unit outside the client’s house. The brass valves were hot to the touch from the midday sun. I twisted them shut rapidly, feeling the resistance of the pressure locking in.

My hands moved to the red and blue hoses, unthreading them with frantic speed. A small hiss of gas escaped, smelling sharp and chemical. I coiled the rubber lines over my shoulder, the grime from the outer casing smearing onto my uniform shirt.

I wiped my hands on a rag that was already black with grease and dust. The grit dug into my skin, but I didn’t stop to rinse them. I threw everything into the back of the van, the metal clanging against the shelving units as I slammed the doors.

You know that feeling when your stomach drops so hard it feels like you missed a step on a staircase? It’s that instant, electric jolt that travels from your gut to your throat. That is exactly what I felt, but it didn’t go away. It just sat there, heavy and cold, making it hard to breathe.

I pulled up the camera feed again at a red light. The nursery was empty. The twins were gone. Nicole was gone.

My heart hammered against my ribs like a trapped bird. I ran the red light, checking the intersection quickly before gunning the engine. If she had taken them, I didn’t know what I would do. I didn’t have a plan. I just had a tire iron under the seat and a lot of adrenaline.

I needed backup. I jabbed at the screen of my phone to call Jennifer. It rang and rang, the sound echoing in the silent cab of the van. Each ring was torture. Finally, her voicemail picked up. Her voice was happy, carefree. It made me want to vomit. I couldn’t leave a message. What would I say? “I think the nanny is hitting the kids”? I hung up and threw the phone onto the passenger seat where it bounced off a stack of invoices.

A landscaping truck pulled out in front of me, forcing me to slam the brakes. My seatbelt locked hard against my collarbone, knocking the wind out of me. The trailer in front was full of grass clippings, and a rake was rattling loose. I didn’t have time to be safe. I swung into the left lane, ignoring the solid yellow line, and floored it past them.

The suburban streets of our neighborhood seemed too quiet. Usually, there were kids playing or people walking dogs. Today, it felt like a ghost town. I pulled into my driveway, nearly taking out the mailbox.

I didn’t bother with the keys immediately. I ran to the front door, my heavy work boots thudding against the concrete path. I tried the handle, shoving my shoulder against the wood, but the bolt held fast. The delay made me frantic. I fumbled with my keychain, my hands shaking so badly I dropped them twice. They jingled on the porch, mocking me.

Finally, the key turned. I burst into the hallway, shouting her name.

— Nicole! Where are you!

Silence answered me. The house was cool, the AC humming softly in the background. It was a stark contrast to the heat outside, but it didn’t make me feel any better. I moved toward the living room first, scanning for anything out of place.

The TV was on, muted, playing a cooking show. A half-folded pile of laundry sat on the sofa. It looked so normal, which made it terrifying. I swung the door to the kitchen open. A bottle of formula was sitting on the counter, uncapped. A small puddle of white milk was dripping onto the floor. To anyone else, it was a spill. To me, in that moment, it was a crime scene.

I grabbed a heavy flashlight from the utility drawer, gripping it like a club. I moved toward the stairs, listening for any sound.

Then I heard it. A low murmur coming from the master bedroom.

I crept up the stairs, trying to be quiet. My heavy boots made that impossible. I reached the landing and saw the door to our bedroom was slightly ajar. I pushed it open, ready for anything.

My chest felt like it was being crushed by a vise. I couldn’t get enough air into my lungs, and black spots danced in my vision. The physical sensation of fear was overwhelming, paralyzing my limbs even as I forced them to move.

I remembered the day the twins were born. The absolute terror and joy I felt holding them for the first time. I promised them I would always keep them safe. I promised Jennifer I would be the protector of this house. The weight of failing that promise crashed down on me.

I saw a future where I had to tell my wife I wasn’t fast enough. I saw the empty nursery, the police tape, the endless news cycles. I saw our lives falling apart because I was too busy fixing someone else’s air conditioner to protect my own family.

I kicked the door wide open.

Nicole spun around. She was holding a kitchen knife.

— Stay back! Or I’ll do it!

I didn’t think. I tackled her.

We hit the carpet with a thud. The knife skittered away under the bed. Nicole screamed, a sound of pure terror that didn’t match the villain I had pictured. I pinned her arms down, breathing heavily.

— Where are they! Where are the kids!

She looked up at me, eyes wide and filled with tears.

— Christopher? What are you doing! Get off me!

— Tell me where the twins are, Nicole! I saw you on the camera! I heard you say you were going to eliminate the witnesses!

She stopped struggling. Her face went from terrified to confused.

— What? No! I was… I was rehearsing!

I froze.

— Rehearsing?

— Yes! For my audition! The twins are in the backyard in the playpen! I was just practicing my monologue while they napped!

I let go of her arms and sat back on my heels. My brain was trying to catch up with the new information.

— You… you’re an actress?

— I’m trying to be! I have a callback for “Zombie High School” tomorrow! The character is a psycho assassin!

I looked under the bed and retrieved the knife. It was plastic. A prop.

I felt all the energy drain out of my body. I slumped against the bed frame, burying my face in my hands. The adrenaline crash hit me all at once, leaving me shaking and nauseous.

— Oh my god. Nicole, I am so sorry.

She sat up, rubbing her wrists. She looked angry, but mostly she just looked shaken.

— You tackled me! You could have hurt me!

— I thought you were hurting the kids! I heard you say “eliminate the witnesses” and laugh like a maniac!

She started to laugh then. It was a shaky, hysterical sound, but it was real laughter.

— That means I was good, right? If I convinced you?

— You convinced me alright. I almost had a heart attack on I-95.

— I’m sorry, Christopher. I shouldn’t have been doing it while I was on the clock. I just really need this part.

— Is the earpiece for lines?

— Yeah. My friend was reading the other part to me over the phone.

I stood up, offering her a hand. She took it, and I pulled her to her feet.

— Let’s go check on the twins.

We walked to the window overlooking the backyard. Sure enough, there they were. Safe in their playpen, asleep under the shade of the big oak tree. They looked peaceful, completely unaware that their father had just performed a SWAT raid on their nanny.

It’s like that moment when you wake up from a nightmare and realize you’re safe in your own bed. The relief washes over you, warm and comforting, but your heart is still racing a million miles an hour. You feel foolish for being so scared, but you’re also just so glad it wasn’t real.

I turned to Nicole. She was brushing dust off her clothes.

— Look, I won’t tell Jennifer about the rehearsing if you don’t tell her I tackled you.

— Deal! But you owe me a raise. Hazard pay!

— Done! Just… maybe practice the romantic comedies next time?

— No promises! The villains have more fun!

I went back downstairs to call my client and apologize for abandoning the job. I walked over to the kitchen sink and splashed cold water on my face. The water dripped down my nose and onto my work shirt, cooling the sweat that was still clinging to me. I looked at the fridge, covered in photos of the twins. The thought of losing them made my knees weak again.

I had a lot of explaining to do, and probably a free service call to give away. But as I looked out the window at my sleeping kids and the aspiring super-villain watching over them, I knew it was worth it.

We assume the worst because we love so deeply, but sometimes the monster in the closet is just a girl trying to memorize her lines.
