The voice came from behind the bathroom glass at 3:14 in the morning.
I was walking past the sink to get a glass of water. The house had been silent for hours. Then I heard it: a voice so much like my mother's that my hand stopped halfway to the kitchen tap.
"Don't open it. The woman who came home from that bus stop is not me."
I stood there in the dark hallway, bare feet on the cold tile, staring at the closed bathroom door. The voice had come from the mirror over the sink. Not from the other side of the house.
I didn't go in. I turned around and went back to bed, pulled the blanket up to my chin, and lay there for the rest of the night counting the cracks in the ceiling paint. One. Two. Three.
I wanted to believe I'd dreamed it.
I knew better.

Twelve days earlier, my mother had called from the bus stop on East Trent.
"Last bus didn't show," she said. "I'll wait for the next one."
The next one was supposed to come in half an hour. It was raining in Spokane that night, the kind of October rain that smells like wet pine needles and bus exhaust. She stood under the metal shelter, the one with the old STA route map taped to the side and the bench that always smells like cigarettes. A few other people waited there too, hoods up, heads down.
Then she saw her.
Twenty feet away, near the edge of the streetlight's reach, stood a woman in the same purple pullover. Same canvas tote bag on her shoulder. Same short chestnut hair tucked behind her left ear. Same way of shifting her weight from heel to heel.
My mother thought it was funny at first. Some kind of weird coincidence. She lifted her hand to wave.
The other woman lifted hers at the exact same moment.
Not a second later. The same moment.
My mother walked toward her. With every step, the resemblance got worse. The mole under her left eye. The faint scar on her chin from a dog bite when she was nine. The way her right foot turned slightly inward when she walked.
When she got within a few feet, something cold moved through her stomach.
"Who are you?" she asked.
The woman tilted her head. And she answered with my mother's voice.
"The question is—who are you?"
My mother backed up. The bus arrived. She got on without looking back. From the window, she watched the woman standing there in the rain. Not moving.
Then the other people at the stop walked right through her.
Like she was nothing but wet light.

I remember the night she came home. She walked through the door and hung her bag on the hook by the stairs. She didn't say a word to me or my father. She just went into the bathroom and stood in front of the mirror for a long time.
A very long time.
I heard the water running. I heard her say something I couldn't catch.
The next morning, the little things started.
Family photos on the mantel were turned around. Leftovers my mother swore she'd put away were gone. My father said she'd mentioned a phone call from Aunt Deb, but Aunt Deb hadn't called in months.
And I started seeing things.
I saw my mother walk into the kitchen while I could hear the shower running in the bathroom. Not one or the other. Both.
One night I came downstairs around ten. Two voices came from the backyard, saying almost the same words at almost the same time. I looked out through the sliding glass door.
Two women stood on the lawn. Both of them had my mother's face. One was crying, her hands pressed to her chest. The other's arms were crossed over her purple pullover, her mouth curved in a way that didn't match her eyes.
I couldn't tell which one I wanted to save.
By morning, there was only one.
—
That's when my mother stopped looking at mirrors.
She would walk past the entryway mirror without turning her head. She washed her hands in the kitchen sink instead of the bathroom. She brushed her hair with her eyes closed. When I asked about it, she said, "The light's bad in there."
But the light wasn't the problem.
The problem was that her reflection never quite matched her movements. A half-second delay. A finger left too long on the wrong side of the glass. A mouth that kept moving after hers had stopped.
I started staying up late. Every night, I walked past the bathroom door. Every night, I listened.
At first, there was nothing.
Then the voice came.
"Don't open it."
Then it came again two nights later, softer, like someone speaking through a wall.
"She's wearing my skin. She knows how to cook my pot roast. She knows the password to my phone. But she doesn't know where I keep the spare key."
I pressed my ear to the door.
"She put it in the drawer with the tea towels," the voice said. "I would never put it there. Ask her."
The next morning, I said, "Mom, where's the spare key to the garage?"
She looked up from her coffee. "In the drawer with the tea towels, honey. Where else?"
My stomach dropped.
I didn't say anything else. I just watched her spread strawberry jam on her toast with my mother's hands.
The real one never touched strawberry jam. She was allergic. Hives on her neck, the whole thing.

The thing about living with a double is that you can't prove anything. You can't call the police. You can't sit your father down and say, "Mom's reflection said she's trapped behind the bathroom mirror." Not unless you want to spend the night in the psych ward.
So I did the only thing I could think of. I stopped sleeping. I paid attention.
I noticed that the woman who made coffee every morning never opened the blinds in the living room before seven. My mother always opened them first thing, even in the dark. I noticed she folded the bath towels in thirds instead of halves. I noticed she didn't recognize the neighbor's dog when it barked outside the fence—she jumped, like she'd never heard it before.
The dog had barked at my mother every single day for three years.
The real one would have said, "Shut up, Cooper."
This one said nothing.
I started locking my bedroom door at night. I put a chair under the knob. Not because I thought she'd hurt me. Because I didn't know what she'd do if she caught me listening at the bathroom glass.
—
On the eighteenth night, I woke up to a sound like fingernails on the inside of a window.
I got out of bed. The house was freezing, like the heat had been turned off hours ago. I walked down the hall. The bathroom door was open. I hadn't left it open.
Inside, the mirror over the sink was dark. Not reflecting the moonlight from the window. Just dark, like a hole in the wall.
And the voice came from it.
"She's going to burn the house down," it said. "Not tonight. But soon. She's going to make it look like an accident. She doesn't need us. She just needed a body."
I stood in the doorway, shaking. The mirror didn't show my face. It showed nothing.
"How do I get you out?" I said.
The voice was very clear.
"Break the glass."
—
I looked at the mirror. It was the one my father had hung the day they moved into that house, twenty-two years ago. They'd bought it at a flea market for eleven dollars. My mother used to say it was the only thing worth saving from that place.
I walked to the basement. I took the hammer from the toolbox on the shelf and weighed it in my hand. It cost nine dollars at Ace Hardware. I remembered my father buying it when I was in middle school.
My other mother was in the living room watching Netflix. I could hear the sound of a cooking show.
I went back upstairs to the bathroom and stood in front of the mirror.
"Do it," the voice said.
I swung the hammer.
The glass didn't just break. It exploded inward, like it had been waiting to be shattered. The pieces didn't fall. They rushed backward, sucked into a space that shouldn't have been there.
A hand shot out. I grabbed it and pulled.
My mother—the real one—fell out of the mirror and onto the bathroom floor. She was wearing the same purple pullover. Her hair was wet. Her breath smelled like rain.
Behind her, the bathroom wall was just drywall again. No hole. No glass. Just a blank space where the mirror used to be.
The hammer clattered against the tile.
Footsteps pounded up the hallway. Fast.
The bathroom door slammed open. The woman standing there had my mother's face twisted into something I'd never seen before. Her eyes went to the empty wall. Then to the woman on the floor.
"You stupid little—"
I didn't let her finish. I threw my weight against the door and shoved it into her chest hard enough to knock her back into the hallway.
I held the door shut with my shoulder while my mother clawed her way up off the tile.
"The key," she whispered, breath rasping. "Under the sink. Taped to the back of the vanity. She never knew about it. It's the only thing that actually locks this door."
I dropped to my knees, one arm still braced against the door as it shuddered under fists on the other side. I found it exactly where she said—a small brass key, taped flat against the wood, cool against my fingers.
I fed it into the lock with a shaking hand and turned it.
The pounding stopped.
Then came a long, low hiss, like air leaving a tire.
Under the door, a fine white powder began to seep through the gap. Not dust. Not sand. Something that glittered like crushed glass.
My mother gripped my hand.
"She came from the mirror," she said. "She can't exist without it."
The powder spread across the hallway floor, then stopped moving. It just lay there, still, like it had never been anything else.
I knelt down and swept a little of it into my palm. It was cold. And it didn't reflect the light.
My mother looked at me. "I need to see the sun."
I unlocked the door. We walked out over the powder. It didn't stick to our feet. It didn't make a sound.
In the living room, the TV was still on. Somebody on the cooking show was laughing.
I opened the front door. The morning was just starting to turn gray over the pine trees.
My mother stepped onto the porch and turned her face toward the light.
For the first time in eighteen days, her mouth eased into something that actually reached her eyes.
The mirror frame still hung on the bathroom wall, but the glass inside it was gone, empty as a window looking into nothing. My father came downstairs later that morning and asked where the mirror had gone. My mother said only, "I took it down. It needed to be gone."
He didn't ask any more questions.
That afternoon, I took the brass key from the lock. I kept thinking about what she'd said — *she can't exist without it* — and about the blank space on the wall, and how a wall like that could always grow a mirror back if you gave it enough time and the wrong kind of dark. I didn't want to find out. I drove to the Spokane River and parked near the footbridge.
The water moved fast, the color of old nickels.
I opened my hand. The key sat there, small and ordinary, warm from my pocket.
I threw it into the river. It didn't catch the light on its way down. It just sank.
I got back in the car and sat there with the engine off, watching rain start to fall on the windshield in fat, unhurried drops.
The wipers stayed off. The glass slowly blurred, then ran clear again in thin streaks, over and over, water finding its own way down.
