At 3:17 a.m., I was told a man had been found with my husband’s phone, documents, and ring. There was only one problem. My husband was asleep beside me.

At 3:17 in the morning, a phone call from the police woke me with the news that my husband had just been killed in a car crash… while that same husband was sleeping beside me with one leg thrown across my body.

“Mrs. Natalie Parker?”

“Yes.”

“This is the New York Police Department. We need you to come identify your husband, Ethan Parker. His SUV crashed into a concrete barrier near the FDR Drive. The driver was pronounced dead at the scene.”

For several seconds, I couldn’t make sense of the words.

I slowly turned my head.

Ethan was right beside me, breathing evenly, his dark hair messy against the pillow.

“Officer… there has to be a mistake. My husband is in bed next to me.”

The line went strangely quiet.

Then the officer spoke again, this time much more carefully.

“Ma’am, I need you to leave the bedroom without waking the man beside you. The identification, vehicle, cell phone, and personal belongings recovered from the crash all belong to Ethan Parker.”

I felt every bit of color leave my face.

Then a voice came from behind me.

“Baby? Who are you talking to about me being dead?”

Ethan was awake.

I forced a smile.

“Some scam call. They’re claiming you were in an accident.”

He gave a drowsy laugh.

“People will try anything now.”

I started to get out of bed, but his hand closed around my wrist.

“Where are you going?”

“Bathroom.”

He released me.

I went inside, locked the door, and called 911 myself.

It wasn’t a scam.

At 2:48 a.m., a black SUV registered to Ethan had veered off the road. The dead driver had Ethan’s wallet, watch, wedding ring, and phone.

Two officers arrived only minutes later.

Ethan was almost unnervingly calm.

He showed them his driver’s license, answered every question, and even joked that whoever stole his SUV had chosen a terrible night to do it.

We were taken to the hospital.

When the dead man’s belongings were laid out on a table, my legs nearly collapsed beneath me.

I recognized the watch I had given Ethan for our fifth anniversary.

His wallet.

His wedding band.

Inside the ring were our initials: E and N.

“Someone could steal all of that,” Ethan said. “It still doesn’t make the dead man me.”

The doctor explained that the body had been too badly damaged for facial identification.

Then he listed the physical similarities.

Male, about thirty-two.

Five feet ten.

A-positive blood type.

Appendectomy scar on the right side.

Ethan was thirty-two.

Five feet ten.

A-positive.

And he had undergone an appendectomy five years earlier.

He lifted his shirt.

The scar was there.

I no longer knew what I was supposed to believe.

By sunrise, we were back at our apartment in Manhattan.

“Natalie,” Ethan said in the elevator, “look at me. It’s me.”

He even remembered exactly where we had kissed for the first time: behind the university library, right after I had eaten garlic bread and spent the entire moment mortified that my breath smelled terrible.

Nobody else knew that story.

I wanted to relax.

Then I watched him press our floor button with his left hand.

Ethan did almost everything with his right.

I told myself I was becoming paranoid.

At nine that morning, the police called again.

Ethan’s SUV had left the parking garage at 10:22 the previous night.

The driver wore a cap, and the surveillance footage didn’t clearly show his face.

But that wasn’t the strangest thing.

The smart lock on our apartment showed no record of Ethan leaving.

According to the system, he had been home the entire night.

After I hung up, another memory surfaced.

Before we went to sleep, Ethan had brought me a glass of milk and insisted I take my insomnia medication.

I fell asleep much faster than normal.

And when the police call woke me, he was wearing gray pajamas.

I could have sworn he had gone to bed wearing black ones.

After Ethan left for work, I opened the smart-lock app.

Three fingerprints were registered.

Mine.

Ethan’s.

And a third one with no name attached.

It had been added eight months earlier.

My hands shook as I opened its access history.

That fingerprint had entered my apartment forty-seven times.

Almost always at night.

And on many of those nights…

Ethan had already been home with me.

At that moment, I realized the dead man might not be the most frightening part of the story.

The terrifying part was wondering who had been sleeping next to me during all those months.

And I still had no idea what I was about to uncover.

I searched the entire bedroom, desperate to find something that made sense.

Eventually, I picked up the gray pajama pants.

Inside the lining, I found an old phone I had never seen before.

There was no passcode.

Only two apps were installed.

Camera.

Gallery.

I opened the first picture.

It was me buying coffee near my office.

The next showed me picking avocados at a grocery store.

Then there was one of me asleep on our couch.

I kept scrolling.

There were photos taken inside my own home.

Me after getting out of the shower.

Me working at the dining table.

Me walking into the kitchen for water after midnight.

In one photograph, I was deeply asleep.

The person who took it had been standing right beside my bed.

My stomach turned.

The most recent video had been recorded at 10:16 the previous night.

Ethan stood near our bed.

I was asleep behind him.

Another man stood facing him with his back to the camera.

Same height.

Same build.

Almost exactly.

Ethan handed him a set of clothes.

“This is the last time,” Ethan said.

“Are you sure she won’t wake up?”

Ethan glanced toward me.

“I gave her enough.”

“And tomorrow?”

Ethan smiled.

“After tomorrow, you’re going to be Ethan Parker.”

The recording ended.

I barely had time to breathe before the front door lock chimed.

“Fingerprint number three. Access authorized.”

I heard the door open.

Ethan was home two hours earlier than usual.

I shoved the phone under my clothes.

“What are you doing back so early?”

“The police are going through things at the company. There wasn’t much point in staying.”

As he spoke, I stared at his hand.

Fingerprint number three had just unlocked the apartment.

He moved toward me.

“You look pale.”

I stepped away before he could touch me.

Then my phone rang.

It was one of the investigators.

He wanted both of us at the station immediately.

There, they showed us footage from a traffic camera.

At 10:43 the previous night, the SUV had stopped at a red light.

For a few seconds, the camera caught part of the driver’s face.

He looked like Ethan.

Not vaguely.

Not somewhat.

He was nearly identical.

Then investigators showed us another image.

At four that afternoon, the same man had entered an auto-parts shop.

He purchased brake fluid.

He also asked an employee where the hydraulic brake lines were located on that model of SUV.

Detective Morgan asked one simple question.

“Mr. Parker, do you have any brothers?”

Ethan slowly crushed the paper cup in his hand.

“Yes.”

I stared at him.

We had been together for nine years.

“What brother?”

He waited too long.

“Aiden. My twin brother.”

The room seemed to tilt.

According to Ethan, Aiden had walked away from the family years earlier.

They barely spoke.

I pulled out my phone.

“You barely speak? His fingerprint has entered our apartment forty-seven times in eight months.”

Ethan’s face went pale.

Then I placed the hidden phone on the table.

The police played the video.

When it ended, no one spoke.

Detective Morgan turned toward my husband.

“Why was your twin impersonating you?”

Ethan looked down.

Then, incredibly, he gave a quiet laugh.

“Because I’m not Ethan.”

I stopped breathing.

The man looked directly at me.

“Natalie… I’m Aiden.”

I slapped him.

“Were you the one beside me last night?”

“Yes.”

“And the other forty-seven times?”

He didn’t answer.

The police escorted me out while they continued questioning him.

Later, Detective Morgan explained what the man claiming to be Aiden had told them.
