The rust-toothed hole in the factory wall smiled a tetanusy smile, hinting of adventure and rebellion.

“I’m going in.”

“Don’t do it, Mike,” Aaron said. “You can’t cuz—” Reasons escaped him, all but a lingering fear that showed as clear as neon on his face.

“I won’t be more than a minute. Relax.”

“There’s probably tramps in there,” Aaron said.

“Naw, this is the only way in, you know that. And grown-ups couldn’t squeeze in here.” They had spent the last forty-five minutes circling the ramshackle building, chucking rocks at the few remaining panes and beating sticks on rusty oil drums to hear the ghostly boom.

“Raccoons then. Maybe. Rats definitely. Definitely.”

Mike ignored him. Of course there’d be rats inside. He’d be disappointed if there weren’t. He squatted down and peered inside the holes, careful not to touch the tetanusy edge. He shucked off his pack filled with the last of the snacks his mom had packed for him when she thought he was going to Aaron’s to play down by his creek. Maybe he should bring that last apple and peanut butter sandwich in case he needed to distract any rats. He picked up a stick instead.

Aaron caught hold of Mike’s ankle just before he started into the hole. “Hey, careful!” Mike said. “I almost clipped my ear on the edge. You want me to get blood poisoning?”

“What if it’s haunted?” Aaron said. His face showed this was the ultimate terror, the one hiding behind all the excuses of tramps and raccoons and rats. Everybody knew this factory was haunted. That’s why the two boys had been drawn there, why they had spent forty-five minutes looking for a way in, even if neither said it out loud, even if Aaron had not admitted it to himself.

“It’s not haunted, stupid,” Mike said. He turned back to the hole and a small shiver went down his back. He hoped it was haunted.

Over twenty years before, when the factory had been recently abandoned, a girl named Katie had crawled inside, maybe through this very hole. There’d been witnesses. The other girls had waited for hours, crying and shouting Katie’s name into the hole over and over until they’d run and told their parents. The police had searched every inch of the factory, but no Katie. All the entrances had been sealed. Mike liked to think that even this hole had been welded shut, that it had opened up on its own after decades of slumber to show its rusted teeth once more.

“Look, I’m going in,” Mike said again. “Come if you want or stay here. I’ll be back in a second.” He ducked under the rusty teeth and eased his body inside.

“You’re stupid, Mike. Stupid!” Aaron smacked his stick off the side of the building, and the metal around Mike boomed and reverberated back and forth, fading off into eternity. Mike pushed forward, trying to ignore the damp mold that squished around his hand and knees.

He came out a moment later into the factory’s main room. Rays from the late afternoon sun invaded the room through the high western windows. The room was a gloomy graveyard of covered machinery and stacked crates. There was no sound from outside—Aaron had evidently stopped whacking on the sides of the building. Nothing moved inside the building. It was as if time had stopped.

There was a crash from nearby, and a stack of pallets fell over. Mike jumped. He took a step towards the hole when a flashlight beam fell on him.

“Who are you?” someone asked. Mike couldn’t see the speaker between the flashlight beam in his eyes and the cloud of dust that the falling pallets had kicked up. He put his hand up to shield his eyes and the beam dropped to the floor.

“Sorry.” It was a girl, Mike could tell. When his eyes recovered from being dazzled by the flashlight, he saw that she was about his age, with curly permed hair and a colorful jacket.

“Who are you?” she asked again.

“I’m Mike.”

“How’d you get in here? Through that hole?” She pointed to the small hole Mike had just come out of. “Are Tammy and Deborah still out there?”

A jolt of fear and exhilaration shot through Mike. He stepped back before he could stop himself. “Are you Katie?”

“Yeah, so?” Katie looked unimpressed. “Did they send you in to find me? I just got here, you know.”

He had found the ghost. She was standing right in front of him, and she didn’t even know she was a ghost.

“What year is it?” he asked.

“What?” She stared him down, then snorted in derision. “1993. Duh. Hey!” Mike had stepped forward and grabbed her hand. She jerked back, yanking her hand free and glaring. “What are you, some kind of pervert?”

She was solid. He had been expecting his hand to go right through her, but she was as solid as he was. He had smelled something from her when she moved back, fabric softener or shampoo or something flowery. Ghosts didn’t have smells, did they?

“We have to get out of here,” Mike said. A thought had struck him, a terrible, impossible thought more horrible than any he had ever had because unlike all his daydreams of monsters and ghosts and aliens, he had a feeling that this one was true. He scrambled into the opening and looked back. Katie hadn’t moved. “Come on!” he shouted and something in his voice made her move to follow him, grumbling a little.

“Keep going,” she said a moment later. “Why did you stop?”

“It’s blocked,” he said. Katie clicked on her flashlight and shone the beam past Mike’s shoulder. The exit was blocked with packed dirt.

“Those jerks!” she shouted. “I knew Tammy was mad at me, but this is too much!” She pushed past Mike to claw at the dirt.

Mike helped her dig, his heart pounding painfully in his chest. This was bad, really bad. A moment later, Katie’s hand broke through into open air. Five minutes later, she pushed herself out into the open and Mike followed, birthing himself out into a stand of ferns.

“What is this?” Katie asked. Her bluster had been left underground. Now she sounded like a scared little girl.

“It was 2017 when I went into the factory,” Mike said. He showed her his phone, and the date it displayed. There was no signal now, not even a single bar. He stood up and looked around. They were in an evergreen forest that stretched as far as they could see in all directions.

“We gotta go back!” Katie cried. “We need to fix this!” She rushed to the hole and stuck her feet in. A moment later, she pulled them out and started crying. Mike saw why; the hole was only two feet deep now.

“Time must have moved differently inside,” he said. “You disappeared ten years before I was born.”

“So what year is this?” Katie asked. She scrubbed her hands across her face, leaving dirt smeared on her cheeks like tribal warpaint.

“I have no idea,” Mike said.

I originally thought of this story for this week’s Friday Fictioneers prompt, but decided to do my own thing when I realized I couldn’t cram it into a 100 words. So what do you think happened? What do you think will happen to Mike and Katie? Should I continue it?
