Liam slouched in his chair, tapping his pencil against the desk as he stared at the clock. The second hand moved sluggishly, and he could almost hear it mocking him. Biology class had never been his favorite, but today was worse than usual. Their regular teacher, Mrs. Dunlap, was out sick, and the substitute was … strange.

Mr. Grimsley was nothing like Mrs. Dunlap. For one, he was tall and lanky, with a shock of wild white hair that seemed to defy gravity. His pale skin had a ghostly hue, making his dark, deep-set eyes look even more sunken. He wore a pristine lab coat that looked like it belonged in a horror movie more than a classroom.

Liam glanced at Maya, his best friend, who sat two rows over. She was staring at Mr. Grimsley, her brow furrowed. It wasn’t just Liam who felt uneasy. Something about the substitute was off.

“Today, we’re going to learn about dissection,” Mr. Grimsley said, his voice smooth and cold, like ice sliding across glass. He flashed a tight-lipped smile that didn’t reach his eyes.

The class collectively groaned. Dissection wasn’t supposed to be until next month, but Mr. Grimsley seemed eager to get started. He moved to the front of the room, his long fingers tracing the edge of the teacher’s desk.

“First, we’ll need some volunteers,” he continued, his smile widening just a little too much. “How about you, Liam?”

Liam’s stomach dropped. He hadn’t raised his hand, but somehow Mr. Grimsley’s gaze had landed on him anyway. It felt like being caught in a spotlight.

“Uh, sure,” Liam muttered, pushing back his chair. His legs felt like jelly as he stood up and walked to the front of the room.

“Good, good,” Mr. Grimsley said, nodding approvingly. “You have just the qualities I’m looking for.”

Liam wasn’t sure what that meant, but the way Mr. Grimsley said it made Liam queasy. As he reached the desk, Liam noticed something odd—a large, metal cabinet in the corner of the room. It was padlocked, and from the way it was positioned, it almost seemed like Mr. Grimsley was guarding it.

“Now, let’s begin,” Mr. Grimsley said, pulling out a tray of sharp instruments. The light above glinted off the metal, and Liam’s breath caught in his throat. There was something about this that felt wrong, but before he could say anything, Mr. Grimsley leaned in close, his cold breath tickling Liam’s ear.

“You’ll do just fine,” he whispered.

Liam swallowed hard, his heart racing as he glanced over the tray of instruments. Scalpels, forceps, and scissors—all gleaming ominously under the fluorescent lights. He wanted to bolt from the room, but his feet felt glued to the spot.

“What’s the matter, Liam?” Mr. Grimsley asked, his voice dripping with mock concern. “Nervous?”

Liam nodded slightly, too uneasy to speak. The class was silent, all eyes on him and the unsettling substitute. Even Maya, who was usually quick with a reassuring smile, looked worried.

“Don’t worry,” Mr. Grimsley continued, his tone silky smooth. “You’ll get the hang of it. It’s just… a matter of practice.”

With that, he handed Liam a scalpel, the cold metal chilling his palm. Mr. Grimsley’s long fingers brushed against Liam’s, sending a jolt through him. The substitute’s eyes gleamed with something that looked almost like excitement.

“We’ll start with something simple,” Mr. Grimsley said, gesturing toward the large metal cabinet in the corner. “Bring the specimen over.”

Liam hesitated, glancing back at his classmates. No one moved or spoke; it was like the whole room was frozen in place. Gathering his courage, Liam took a shaky step toward the cabinet.

As he reached for the padlock, Mr. Grimsley suddenly appeared beside him, his movements eerily quick. “Careful now,” he whispered. “This specimen is… delicate.”

Liam’s hand trembled as he unlocked the cabinet. The door creaked open, revealing shelves filled with glass jars, each containing something strange and grotesque. Floating in murky liquid were small creatures—frogs, lizards, and things Liam couldn’t even identify. But it was the jar on the bottom shelf that caught his eye.

It was larger than the others, and inside was a shape that made Liam’s blood run cold. It looked like a hand—but not just any hand. It was small, like a child’s, and stitched together with different shades of skin. The fingers were mismatched, some longer than others, and the nails were ragged.

“Ah, yes,” Mr. Grimsley said, almost reverently. “The beginnings of my masterpiece.”

Liam recoiled, nearly dropping the jar. “What is this?” he whispered, horrified.

Mr. Grimsley’s smile widened. “A work in progress,” he said simply. “A new kind of student, one that embodies the best qualities of all.”

Liam felt sick. He stumbled back, his mind racing. He had to get out of there, but the door seemed so far away, and Mr. Grimsley’s presence loomed over him like a dark shadow.

Just then, the classroom door creaked open, and Maya stepped forward. “Liam,” she called softly, her voice trembling. “What’s going on?”

Mr. Grimsley’s eyes flicked to her, and for a brief moment, his smile faltered. But then it was back, more sinister than before. “Ah, another volunteer,” he said, his tone as smooth as ever. “Perfect timing.”

“No,” Liam said, his voice firmer this time. “Maya, get out of here!”

Maya didn’t move. Her eyes were locked on the jar in Liam’s hand, her face pale. “What is that?” she asked, horrified.

“It’s nothing you need to worry about,” Mr. Grimsley said, stepping between them. “Liam and I were just having a little… lesson.”

“Leave her alone,” Liam said, surprising himself with the strength in his voice.

Mr. Grimsley turned to him, his smile fading into a thin line. “I see,” he said slowly. “You’re more troublesome than I anticipated.”

Before Liam could react, Mr. Grimsley reached out and snatched the jar from his hand, placing it back in the cabinet. He slammed the door shut, locking it with a swift motion. “Perhaps a different approach is needed,” he murmured.

Liam’s heart pounded in his chest. He had to do something, but what? Then he remembered—science. It was Mr. Grimsley’s weapon, but it could be his too.

“How about we finish today’s lesson early?” Mr. Grimsley suggested, his voice dripping with false kindness. “You both look like you could use a break.”

Liam and Maya exchanged a glance. This was their chance.

“Yeah, I think that’s a good idea,” Liam said, trying to keep his voice steady.

Mr. Grimsley nodded, but his eyes never left them as they backed toward the door. As soon as they were out of the classroom, they bolted down the hallway, not stopping until they were outside, gasping for breath.

“What was that?” Maya panted, looking over her shoulder as if expecting Mr. Grimsley to appear any second.

“I don’t know,” Liam replied, his mind racing. “But we need to figure it out—before it’s too late.”

Liam and Maya ran until their legs burned and their lungs screamed for air. They didn’t stop until they reached the far side of the schoolyard, hidden behind the old oak tree where they used to play tag in elementary school. It was a place that felt safe, at least for the moment.

“What do we do now?” Maya asked, her voice shaking. She was trying to stay calm, but Liam could see the fear in her eyes.

Liam leaned against the tree, trying to catch his breath. “We need to tell someone. The principal—someone has to know what Mr. Grimsley is doing.”

Maya nodded, but then her face fell. “But what if no one believes us? I mean, it sounds crazy. A teacher making a monster out of students? They’ll think we’re making it up.”

Liam knew she was right. The story sounded insane, even to him. But he also knew they couldn’t just do nothing. He thought back to the jar in Mr. Grimsley’s cabinet, the hand floating inside. He shuddered at the memory.

“We have to get proof,” Liam said, determination hardening his voice. “If we can show someone what he’s doing, they’ll have to believe us.”

Maya’s eyes widened. “You want to go back in there? Are you nuts?”

Liam shook his head. “Not now. Tonight. We’ll sneak into the school after everyone’s gone. If we can get into that cabinet and take pictures, we’ll have evidence.”

Maya hesitated, biting her lip. “That’s dangerous, Liam. What if he catches us?”

Liam looked at her, trying to muster all the courage he could. “We’ll be careful. But we can’t let him keep doing this, Maya. What if more kids disappear?”

Maya sighed, then nodded. “Okay. Tonight. But we have to be really careful.”

The rest of the school day dragged by in a blur of nerves and dread. Liam and Maya could barely focus in their other classes, constantly glancing at the clock, counting down the minutes until they could put their plan into action.

When the final bell rang, they slipped out of school quickly, avoiding Mr. Grimsley’s classroom entirely. They parted ways, agreeing to meet back at the school later that night. Liam spent the rest of the afternoon at home, trying to calm his racing thoughts. His parents noticed he was unusually quiet, but he brushed off their concerns, claiming he had a lot of homework.

As the sky darkened, Liam packed a small backpack with a flashlight, his phone, and a notebook. He waited until his parents were watching TV in the living room, then quietly slipped out the back door.

He met Maya at the school’s back gate, both of them bundled in hoodies to ward off the evening chill. The school loomed ahead of them, dark and silent, like a sleeping beast. Liam’s stomach twisted with anxiety, but he pushed it aside. They had to do this.

“Ready?” Maya whispered, her breath visible in the cool night air.

Liam nodded. “Let’s go.”

They crept around the side of the building to a window they knew was always left unlocked. Liam carefully pried it open, wincing at the faint creak, and boosted Maya up before climbing in himself.

The school was eerily quiet, the usual hum of activity replaced by the oppressive silence of the empty halls. Their footsteps echoed faintly as they made their way to Mr. Grimsley’s classroom.

When they reached the door, Liam hesitated. He half expected Mr. Grimsley to be standing there, waiting for them with that creepy smile. But the hallway was empty.

Liam took a deep breath and pushed the door open. The classroom was just as they had left it, but the sight of it in the dark made the room even more sinister. The metal cabinet in the corner seemed to loom larger, its shadow stretching across the floor like a gaping maw.

Maya pulled out her phone, turning on the flashlight. The beam cut through the darkness, illuminating the locked cabinet.

“Here goes nothing,” Liam muttered, pulling a small screwdriver from his backpack. He had grabbed it from his dad’s toolbox, hoping it might work on the padlock. He knelt by the cabinet, his hands trembling slightly as he tried to pry the lock open.

Maya stood watch, her flashlight sweeping over the room, her ears straining for any sound. The seconds ticked by, each one feeling like an eternity.

Finally, with a soft click, the lock popped open. Liam exchanged a quick, triumphant glance with Maya before carefully opening the cabinet doors.

The smell hit them first—a pungent, chemical odor that made their noses wrinkle. Inside, the shelves were lined with jars, just as they had seen earlier. But now, in the eerie light of the flashlight, the contents looked even more grotesque. Limbs, organs, and other unidentifiable parts floated in murky liquid, all stitched together in horrifying combinations.

Maya stifled a gasp, her hand flying to her mouth. Liam quickly pulled out his phone and started taking pictures, capturing as much evidence as he could.

But then, something at the back of the cabinet caught his eye. It was a larger jar, hidden behind the others. He reached in and carefully pulled it forward. Inside was a face—patchwork, like the rest of the parts, but unmistakably human. Its eyes were closed, but as Liam stared, they suddenly snapped open, locking onto his.

Liam yelped and dropped the jar, which hit the bottom of the cabinet with a sickening thud but didn’t break. The eyes in the jar rolled back, and the lids slowly closed again.

“We need to get out of here,” Liam whispered, his voice shaking.

Maya nodded, already backing toward the door. But just as they turned to leave, the classroom door swung open with a creak.

Mr. Grimsley stood in the doorway, his face twisted in a dark, angry scowl. “And where do you think you’re going?”

Liam’s heart pounded in his chest as Mr. Grimsley stepped into the classroom, blocking their only exit. The door clicked shut behind him, and the sound echoed ominously in the silence.

“I must say, I’m disappointed,” Mr. Grimsley said, his voice low and cold. He took a slow, deliberate step forward. “Curiosity is a dangerous thing, you know.”

Maya clutched Liam’s arm, her eyes wide with fear. Liam’s mind raced, searching for a way out, but Mr. Grimsley’s presence seemed to suck the air from the room, leaving them both frozen in place.

“Breaking into my cabinet, snooping around in my work,” Mr. Grimsley continued, shaking his head. “I expected more from you, Liam. Such potential, wasted on foolishness.”

Liam swallowed hard, trying to find his voice. “We—We know what you’re doing,” he stammered. “We have proof.”

Mr. Grimsley’s eyes narrowed, and he let out a soft, humorless chuckle. “Proof? You think anyone will believe the word of two meddling children? No, I’m afraid that’s not how this will end.”

He moved closer, his shadow stretching across the room like a dark specter. “You’ve seen too much. And now, you’ll become part of my work.”

Liam’s stomach churned as Mr. Grimsley reached out a hand toward them, his fingers long and bony. But just as he was about to grab Liam, Maya stepped forward, her flashlight aimed directly at Mr. Grimsley’s face.

“Stay back!” she shouted, her voice trembling but determined.

The sudden light seemed to startle Mr. Grimsley, and he recoiled slightly, his expression twisting into one of rage. “You think you can stop me with a flashlight?” he sneered.

Liam seized the moment. “Maya, the beakers!” he whispered urgently.

Maya glanced at the lab table, where rows of beakers filled with strange, bubbling liquids were lined up. Without hesitation, she grabbed one and hurled it at Mr. Grimsley.

The beaker shattered against his chest, and the liquid inside hissed as it soaked into his lab coat. Mr. Grimsley screamed in pain, staggering back as the substance began to eat through the fabric, sending up tendrils of acrid smoke.

Liam and Maya didn’t wait to see what would happen next. They bolted for the door, shoving past Mr. Grimsley as he writhed in agony. They raced down the hallway, the echoes of Mr. Grimsley’s screams following them.

They burst out of the school, gasping for breath, and didn’t stop running until they were several blocks away. Only then did they dare to look back.

The school loomed dark and silent behind them, no sign of Mr. Grimsley in pursuit. Liam leaned against a lamppost, trying to catch his breath.

“We did it,” Maya panted, her face pale but relieved. “We got away.”

Liam nodded, but his mind was still racing. “We need to show those pictures to someone. The police, the principal—anyone who will listen.”

Maya pulled out her phone, her hands still shaking, and quickly sent the photos to her own email as a backup. “We should go to the police station now,” she said. “They’ll have to believe us after they see this.”

But just as they turned to head toward the police station, they heard a faint, familiar voice behind them.

“Well, well, well….”

Liam and Maya whipped around, their blood running cold. Standing under a flickering streetlight was Mr. Grimsley, his lab coat torn and stained from the chemicals, but very much alive. His face was twisted into a cruel smile.

“You didn’t think it would be that easy, did you?” he asked, his voice smooth and taunting. He raised one hand, and in it was a small, remote-like device with a blinking red button.

Liam and Maya didn’t have time to react before Mr. Grimsley pressed the button. A loud, high-pitched whine filled the air, and suddenly the ground beneath their feet began to tremble.

“What’s happening?” Maya cried, grabbing onto Liam to keep her balance.

The ground cracked open, and from the fissures emerged a massive, grotesque figure—a patchwork monster, cobbled together from the body parts in Mr. Grimsley’s lab. It was a horrifying amalgamation of limbs, eyes, and mouths, stitched together haphazardly, yet somehow, it moved with a terrifying purpose.

“Meet my greatest creation,” Mr. Grimsley said with pride. “A new breed of student, loyal only to me.”

The monster lurched toward them, its many eyes glowing with a sickly green light. Liam and Maya backed away in horror, but the creature was too fast. It swiped at them with one of its many arms, knocking them to the ground.

Liam’s mind raced. They couldn’t fight this thing head-on—it was too strong. But maybe they didn’t have to.

“Maya, the phone!” Liam shouted, struggling to get to his feet.

Maya fumbled with her phone, managing to pull it out just as the monster loomed over them. She quickly navigated to the email app and hit send, sending the pictures to the police and the principal.

“Run!” Liam yelled, grabbing her hand and pulling her away from the monster.

They sprinted down the street, the monster crashing through the pavement behind them. It was relentless, its many limbs reaching out to grab them as they dodged and weaved through the narrow alleyways.

Just when they thought they couldn’t run any further, they heard the wail of sirens in the distance. Blue and red lights flashed as police cars rounded the corner, speeding toward them.

Mr. Grimsley’s face twisted in rage as he realized what had happened. “No!” he shouted, trying to call the monster back, but it was too late.

The police cars skidded to a stop, and officers jumped out, guns drawn. The monster hesitated, confused by the sudden commotion, and in that moment of hesitation, one of the officers fired a shot that hit the remote in Mr. Grimsley’s hand.

The remote exploded in a shower of sparks, and the monster let out a deafening roar before collapsing into a heap of lifeless parts. Mr. Grimsley staggered back, his plan falling apart before his eyes.

“Get him!” one of the officers shouted, and they swarmed Mr. Grimsley, cuffing him before he could make another move.

Liam and Maya stood at the edge of the scene, breathless and shaken but relieved. They watched as Mr. Grimsley was dragged away, still snarling and muttering about his “masterpiece.”

“It’s over,” Maya whispered, leaning against Liam for support.

Liam nodded, though a part of him couldn’t shake the feeling that this was far from the end. But for now, they were safe, and that was all that mattered.

Epilogue

The next day, the school was abuzz with the news of Mr. Grimsley’s arrest. The principal had been shocked by the photos Liam and Maya had sent, and the police had confirmed the existence of the underground lab where Mr. Grimsley had been conducting his horrific experiments.

Liam and Maya were hailed as heroes, though they were more than happy to avoid the spotlight. They just wanted things to go back to normal—or as normal as they could be after everything that had happened.

But as they sat in the cafeteria, listening to the chatter of their classmates, Liam couldn’t shake the feeling that something was still wrong. He glanced around the room, his eyes landing on the new substitute teacher who had just arrived that morning.

The man was tall and thin, with a neatly trimmed beard and a kind smile. He seemed perfectly normal, but as Liam caught his eye, he felt goose pimples pop up and tingle on his forearms.

The new teacher smiled at him, and for a split second, Liam thought he saw a flash of something dark and sinister behind those eyes. But then it was gone, and the teacher turned away, greeting another student with the same warm smile.

Liam tried to shake off the feeling, but as he looked at Maya, he saw the same unease reflected in her eyes. They didn’t say anything, but they both knew the truth:

Some nightmares never really end.
