Three Seconds Behind

Daniel found the mirror at a flea market on a Sunday, leaning against a table of old radios. Tall, dark wood, the glass a little cloudy at the edges the way old mirrors get. The man selling it said it came out of a house on the other side of town, a house that had been empty for years. He said it like it was a selling point. Daniel liked the frame. He paid forty dollars and carried it home on his shoulder, the glass catching the sky in pieces as he walked.

He hung it in the bedroom, across from the bed, because that was the only wall big enough.

The first night, he noticed it was slow.

He was brushing his teeth, half-asleep, and he raised his hand to scratch his neck — and in the mirror, his hand came up a beat later. Not much. A fraction. The kind of thing you notice and then immediately talk yourself out of noticing. He was tired. The light was bad. Mirrors are funny things.

The second night, the lag was worse. He waved at himself, and the man in the mirror waved back a full second later, like a video call with a bad connection.

On the third night, he stood in front of it and clapped, once, sharp.

The reflection clapped two seconds later.

And then it kept its hands together. Just for a moment. Just long enough for Daniel to notice. Like it was holding the applause.

He stopped looking at it after that. He got dressed with his back to it. He brushed his teeth in the bathroom. He told himself he would take it down on the weekend, when he had time, when he had help, when he wasn't so tired.

On the fifth night, he woke up at 3:12 in the morning because he could hear someone breathing in the bedroom. Slow, even breathing. His own breathing. But he was already awake, and he was holding his breath.

In the mirror, the man in the bed was asleep. Daniel could see him — himself — lying there, chest rising and falling, peaceful. And Daniel was sitting up in the actual bed, staring at the mirror, watching himself sleep.

He didn't sleep again that night. He sat in the kitchen with the lights on until the sun came up, and when the sun came up, he went to the bedroom with a hammer, because he was done being scared of a piece of glass.

He hit it once, in the center.

The mirror didn't shatter. It cracked — one long line, top to bottom, like a seam — and then it was quiet again.

That should have been the end of it. He should have dragged it to the curb and been done.

But when he looked at the crack, he saw his reflection in two halves. And the two halves were not in sync. The left one raised its hand. The right one raised its hand a second later. He was looking at himself in stereo, out of time with himself, and both of them were smiling.

He hadn't been smiling.

He covered the mirror with a sheet. He nailed the sheet to the frame. He put a chair in front of it. He told himself it was over.

On the seventh night, the sheet was on the floor.

The mirror was uncovered, and the man in it was standing. Daniel was lying in bed. The man in the mirror was standing, fully dressed, in the clothes Daniel had laid out for the morning. He was looking at Daniel the way you look at someone you're about to replace.

“Your turn,” the reflection said. It didn't move its mouth. The voice came from the glass itself, from everywhere and nowhere, and it sounded exactly like Daniel, except for the part that didn't. The part that was patient. The part that had been waiting a long time.

Daniel got out of bed. He didn't know why he got out of bed. His body did it without asking him.

He walked to the mirror. He raised his hand.

This time, he was the one who was late.

Daniel raised his hand, and this time he was the one who was late.

He didn't understand at first. He was still standing in the bedroom. He could still feel the floor under his feet, the frigid air on his skin. But everything was wrong in a way he couldn't name — the light was flatter, the sounds were muffled, like the world had been wrapped in glass. He could see the bedroom, his bedroom, but it was on the other side of something. And his double — the man with his face, in his clothes — was walking toward the door, into Daniel's life, with Daniel's walk, humming a song Daniel had never learned.

He tried to shout. His voice came out a second late, and it came out of the mirror.

That was when he understood. He wasn't in the bedroom anymore. He was in the glass.

He watched his double make coffee the next morning. It got everything almost right. Almost. It put sugar in the cup — Daniel took his black. It hummed while the coffee brewed — Daniel never hummed. Tiny details. The kind of things nobody notices until they add up, the way a face can be almost right and still be wrong.

At work, the double answered to his name. It laughed at jokes Daniel would have laughed at. It even remembered the passwords. But it called his sister by the nickname she had hated since she was twelve, and it didn't flinch when their mother called, and it held its fork in the wrong hand at lunch. His coworker, Priya, stared at it for a long moment across the table and said, “You okay? You seem... off today.”

The double smiled Daniel's smile. “I'm fine,” it said. “Just tired.”

Priya didn't look convinced.

Back in the glass, Daniel wasn't alone.

There were others in there. He found them the way you find things in a dark room — slowly, by touch. Faces, pressed against the inside of the mirror like people pressed against a window. An old woman with her hair in a bun. A young man with a chipped tooth. A little girl holding a doll with no eyes. They were all a little behind, all a little late, all watching their own doubles live their lives on the other side.

“How long have you been here?” Daniel asked the old woman. His voice came out late, and it echoed.

“Since 1962,” she said. “It took me three seconds at a time.”

That was the rule, she told him. The mirror doesn't steal you all at once. It takes you a second at a time. Three seconds behind, then five, then ten, until you're the echo and it's the voice. And the only way back — the only way anyone had ever gotten back — was to make it late. The double only knows what it has seen. Give it something it has never seen you do, and it stumbles. And when it stumbles, the glass opens.

Daniel waited. He watched his double move through his life, getting better at being him every day, and he waited for the one moment when the double would have to look in a mirror. Because the double always looked. It checked itself constantly — in windows, in the bathroom mirror, in the dark screen of his phone. It needed to see the face to hold the shape.

And Daniel had left it a crack.

The crack he had made with the hammer, that first morning. The one long line, top to bottom, like a seam. The double avoided it. Every time it looked in the bedroom mirror, it stood to one side, where the glass was whole.

So, Daniel stood at the crack. He waited. And when the double finally came to the mirror that night — to check its hair, to practice its smile — Daniel reached through the seam and grabbed its wrist.

For one second, the world flipped. The double was the one who was late. Daniel pulled, hard, with everything he had, and he felt himself sliding through the glass, cold, bright, and terrible, like being born backwards.

He landed on the bedroom floor. Gasping. Alive. Himself.

The mirror was empty. The double was gone — dragged in, trapped behind the glass where Daniel had been. He could see it in there, his own face, pressed against the inside, mouthing something he couldn't hear.

He stood up. He went to the mirror. He raised his hand.

The reflection raised its hand exactly on time.

Daniel exhaled. He almost laughed. He was back. He was himself.

Then he noticed the reflection's eyes.

They blinked a half-second before his did.

The reflection got there first.

And Daniel understood, too late, that the thing that had come through the crack wasn't him at all. It was the double, wearing his relief, wearing his face, wearing his life — and the real Daniel was the one in the glass now, watching, three seconds behind, forever.
