A/N:

This is my Halloween special. I wanted to challenge myself into doing something awesome. Giving myself a deadline was hard but I'm glad I made it in time. I rushed the ending but I couldn't think of anything else.

Thanks to everyone who liked and favorited this story. It's thanks to you that motivated me to get this done. So kudos.

Chapter 4

Scott knew adult stuff would happen after that first Dare Stiles was right that it would only affect the adults in the group. Derek had just gotten a card telling him to bottom for his uncle. Which eww.

Derek refused to do it, Peter is his uncle after all.

Not wanting to stick around for this Scott followed Stiles out of the room. He really didn't need to know what would happen. Obviously, something was happening and it must have something to do with Stiles plan. Scott wasn't stupid he knew Stiles better than anyone else. So a half-baked plan hiding the real plan from sight was easy enough to sniff out.

Scott lost sight of Stiles till he noticed Stiles scent led toward the basement door. Stiles went into the basement, Scott shouldn't be as surprised as he is to see this. It was just like Stiles to jump head first into a dangerous situation without any backup. Walking down the stairs Scott saw Stiles standing before a door not moving. Walking up to him Scott saw that Stiles didn't see him, that he was completely focused on that door. Even standing right by the others side got no response.

Suddenly Stile's hand grabbed the doorknob.

"Stiles?" Scott touched his shoulder only for him to scream and punch him.

"Oh my god Scott, what the hell? Are you trying to kill me?"

Oww damn, he hits hard.

"Sorry, but I've been trying to get your attention for a while now.."

"You have?" Confused.

Could I have fallen for his trick?

Opening the door Scott wondered why Stiles was looking at him like that. "Come on let's go. You wanted to investigate right?"

"Right so that happened. Let's go."

Confused Scott just ignored it. Stiles often said things that made no sense to him. Best to change the subject.

Inside the door led to a stone hallway that had no ending in sight with doors on both sides. Scott didn't like this it was like this person stole a bunch of scenes from horror movies and just mushed them together hoping for the best. Once both boys stepped inside the door slammed shut behind them locking them inside.

Scott tried to break the door down but no luck. Any damage was magically fixed, repairing instantly. Having no choice but to continue onward they tried the first two doors on both sides only to find them locked. The third try opened the second door on the right.

Click

The door opened. Stiles used his phone as a flashlight together they thoroughly searched the room. There must be some kind of clue they had to find inside. Otherwise why the duplicity.

Scott watched as Stiles knocked on the walls. This reminded him of that scene in Roger Rabbit when the Judge? did a song by knocking on the walls. Was Stiles looking for a secret room?

Click

Scott stared dumbfounded. Stiles had found a secret room. How is that even a thing?

The wall pushed inward to total darkness. High on the adventure, the boys stepped into the room.

Erica and Boyd played their part doing what Stiles told them to do. When Derek and Peter refuse to play follow Scott's path.

They went upstairs to the third-floor landing tracing Scotts steps as soon as Stiles left the living room. They had to know why they tried to lure Scott away. Not being able to scent the air for the stranger's trail Erica and Boyd split up. They would be better able to cover more ground this way. No one touched one of theirs and lived.

"I can't smell Allison." Said Boyd.

Erica wanted to know why that was relevant.

He just looked at her.

Why is he looking at me like that? So what if Allison's scent is nowhere to be found how is that important? The girl wasn't even here.

Oh,

"You understand?"

"Yes, your right why can't we smell her? Her scent should be all over the top floor. I can only smell Scott and us."

Nodding Boyd agreed.

If Allison was really searching the third floor yesterday like Scott thought the entire floor would be drowned in her scent but neither Erica or Boyd could smell her.

Pitch black Stiles couldn't see a thing, not even with the flashlight on his phone. It was like the darkness was absorbing the light leaving nothing but an endless abyss. Walking in a bit further he tripped over a table.

"Stiles are you okay?"

Embarrassed he answered, "Yeah, I can't see a thing can you?"

"No. I don't like this."

Standing up Stiles felt with his hand, moving it along slowly he started when he touched something. He couldn't see a thing not even when he shown the light directly on the thing.

"What is it? Did you find something?"

"I don't know." Feeling along its base he thought it might be a flashlight. Really. A flashlight. It would figure that they couldn't use anything else but this flashlight to see.

They had to play the game it seemed.

Finding the button he pushed it.

A bright light blinded the duo for a second. Eyes adjusted Stiles swept the beam across the room. He wished he hadn't. The entire room was covered in blood. Bright red splashes littered the walls and floors painting the room in a dark macabre glow. The only furniture was the table Stiles found the flashlight on.

Lightheaded Stiles didn't notice Scott leading him out of the room. Grim-faced Scott had him sit with his head between his legs. Stiles really couldn't handle blood. Nasiated Stiles never noticed Scott taking the flashlight and entering the room they just vacated with a determined look on his face. If he had he would have stopped him. If only they had known what horrors that would be unleashed that night. Would they have been able to stop it?

The first four rooms were a bust they couldn't open them. The fifth door opened up to a secret passage that had a stairway heading up. To the attic probably. Erica agreed Boyd should look while she checked the other rooms. Splitting up, each agreed to meet up again in an hour. Agreeing that the living room was a safe bet.

Erica tried the next door when she heard a door opening behind her. Hiding she watched to see if anyone was coming out.

Seeing no one she concentrated on her hearing. She was able to make out a faint heartbeat leading towards the stairs going to the lower floor. Sneaking into the room followed by the closing door Erica hid behind a chair hoping she was alone. She really hated an enemy she couldn't see, hear, or touch.

Crouching she crawled out from behind the chair. Seeing nothing she took the risk and stood up.

Computer monitors? Was the room just a security office?

No, that's not right. Walking toward the monitors Erica saw the house on the screens. Nearly every room had a camera in it. The front door, Kitchen, and hallways. The second and third-floor hallways and even outside the house why?

Could Stiles be right?

Hearing the door open, startled Erica fell back and hit the wall triggering the wall to slide out of place. Falling backward she never saw who entered the room but knew their scent was familiar.

The wall slid back into place saving Erica from being found.

Tumbling backward Erica slid down a long tunnel managing to turn herself she stared in horror at the slide of death she found herself on.

How the fuck is this inside a house!

Sliding very fast Erica didn't have much time to move out of the way to avoid being shish kabob by the spinning blades of death. Sliding down she turned right then left then right again. Screaming Erica tried to grab the sides of the tunnel to stop herself. A big arse spinning blade filled the bottom of the slide.

Leaving Stiles behind Scott steeled himself and went back into the room. Using the flashlight he searched the room making sure they didn't leave anything behind. Taking extra care not to slip into the mess Scott noticed a hatch in the floor. Locked it needs a key.

Maybe the key is in the other room?

Walking back Scott heard a baby's cry. Running he made it just in time as the wall slammed shut locking it back in place.

Bang

Bang

Bang

Scott dragged Stiles along back into the hallway. If horror movies have taught him anything never follow the sounds. A baby's cry is usually followed by death.

"Scott? What happened did you find something?"

"No, let's check another door." No way in hell was he going back in there.

Dragging Stiles behind Scott chose a random door and opened it.

This door led to another hallway.

Slam

Locked in they had no choice but to continue forward.

"This is so stupid. What the hell is with all the cheap scares." Stiles spit.

"We need to get out of here."

"Yeah, we have to get back upstairs."

None of the doors would open.

"Are we trapped? Fuck that, Scott slam into that door." Stiles randomly pointed toward a door.

Shrugging Scott squared his shoulders and ran... In to nothing. The door opened on its own.

"Good job buddy."

The room looked like an office it had file cabinets all along the wall on the right, a group of monitors straight ahead and a map of the house on the left.

Scott checked the cameras looking between monitors.

"They were watching us." Scott felt dirty. This guy needs to be stopped.

"Hey, I think I found something." Called Stiles.

"Look there's a button behind the map. Should we push it?"

Apprehensive, Scott was worried, should they?

"Yeah, let's see what will happen."

Grabbing each other's hand they agreed no matter what happens they are in it together.

Pushing the button made part of the wall open up.

Together they stepped inside. Using the flashlight Scott swung the beam around taking in all he could see.

"Pictures?" Why are there pictures hidden away?

Searching through the pictures on the wall Stiles gasped. "Scott these are the missing kids." "Are you sure?" "Yes, look this is the kid that went missing a few days ago, so this must be the one that went missing last night."

"Why are they hidden away in the house we were kidnapped too?"

"I don't know but I think we found where the kids were taken too."

Scott had a bad feeling they would need to go back to that room.

"I found this key wonder where it goes."

Bad feeling confirmed.

Erica screamed she couldn't get a good hold there was nothing to grab onto. The slide was too slimy she couldn't stop.

"AHHHHHhhhhhhhhh"

A hole had opened up, swallowed Erica and deposited her on the couch in the living room.

Freaked out she didn't move not even noticing she was safe.

She had nearly died, killed by her own folly.

Breathing hard Erica rolled of the couch taking stock she patted herself down making sure she hadn't lost anything.

Laughing Erica was just happy to be alive. That was some messed up shit. She thought for sure she was dead.

"Erica?"

"Allison. What are you doing here?"

Walking up the stairs Boyd listened carefully. He couldn't hear anything nor did he smell anything wrong or strange. Cautiously he walked up to a door listening he didn't hear anything so he opened the door. Fear, blood, and gore the stench overpowered him. Covering his nose Boyd stepped into the room.

Cages littered the floor of the room. Running his hand along the wall he found the light switch. He turned it on.

Covering his mouth he swallowed consistently to keep from throwing up. Inside the cages were dead bodies of children. What was left of them anyway. Parts were thrown about the room like the guy was playing with them.

Boyd couldn't stay inside the room he had to leave. Now they just had to call the sheriff and get these kids back to their family's. If this wasn't the missing kids. He hated to think that another sick fuck was in their town.

Leaving Boyd nearly didn't hear the soft whimper behind him. An immediate about-face Boyd called out. Another whimper answered him. Searching the cages he couldn't find them. None of the kids in the room were alive.

There must be a hidden room he can't see.

Running his hands across the walls he felt an indent someone covered a door up with wallpaper. Ripping the wallpaper away with his claws Boyd uncovered a door. Opening it up he saw the body of a young child.

Quickly he dropped down checking for a pulse. The child gave out a whimper, his pulse strong. A surprising scent met Boyd's nose the child was a were. Not a wolf though something else.

Were the other children weres? That is no reason to slaughter children.

This guy is a hunter a truly sick person that targets children. They must have been taken because only Derek and Peter are adults. And Stiles is the Sheriffs son. What better way then to stop an investigation by using the disappearance of the Sheriff's son. But they messed up with letting Erica outside they had to allow everyone outside. Thinking the Sheriff was still searching for his son they took another kid.

These sick bastards deserve death. Taking the kid Boyd used his phone to text the Sheriff. Stiles had given them his dads number in case of an emergency.

Picking the child up Boyd walked out of the hidden room and headed for the door to walk down the stairs.

Running he listened for the others two people are in the living room he headed there.

"Erica I need your help." He called out.

"Boyd? Oh my god!"

She quickly ran off while he laid the child down on the couch covered in blood.

What! Why is it... Where did all that blood come from?

"Here." She handed him a wet towel. He wiped the child down removing the blood from the face and checking for any wounds.

"Where did you find him?"

Turning to her he stopped and blurted "What the hell happened to you."

As tears filled her eyes he quietly panicked letting her cry on him as she explained what happened.

Disbelief, this really was a house of horrors. Erica was nearly killed by a spinning blades of death tunnel slide. That room he found the children in and who knows what the others are dealing with. They needed to leave now.

"Where did Allison go?"

"Allison? I didn't see her." There had been two heartbeats, right?

"I texted the Sheriff he should be here soon."

"Boyd, what happened? How did you find the kid?" Realizing he never said he explained what he found.

A little green Erica hoped the Sheriff hurried up. They needed help.

As soon as they left the room the hallway doors opened up. Bracing himself Scott let Stiles drag him along.

"That's not ominous at all." Quipped Stiles.

"Maybe we should go back now?"

"I know we are close to the truth. I need you, Scott."

"How do you know?"

"Things are getting scary and so far this guy has based everything on horror movie logic."

"That makes sense. Okay, I'm with you to the end."

They searched all the rooms that opened in the hallway Scott just grabbed all the folders and took pictures with his phone of what he couldn't. Moving fast they finished quickly not wanting to disturb the crime scene.

Stiles flipped through the folders and looked through the pictures Scott took. He didn't want to believe it but the evidence was damning. Stuffing everything into a pillowcase Stiles carried it to the next room. Not wanting to go back in there he gave the flashlight to Scott wishing him luck.

Taking a deep breath Scott hit the switch and entered the hidden room. Using the flashlight he checked to make sure nothing scary and or murderous was inside with him.

Neeling down he used the key to open the hatch.

Click

All of a sudden light illuminated the room he was in. Blinded for a second Scott froze using his senses to search for him. He heard Stiles nothing else. Opening his eyes he was dumbfounded there was nothing, no blood no anything just the opened hatch before him.

Opened?

Stumbling backward he let his imagination get away from him.

"Ott... Scott, can you hear me?

"Stiles." Grabbing him, he hugged his brother close.

Getting a hold of himself he apologized for freaking out.

"It's okay man I would have done worse."

"Have I said how much I love not having asthma anymore."

"Constantly." Joked Stiles.

"You ready?"

"In too the breach we go."

They climbed down the ladder. The room they dropped down from only had two rooms. One door had a staircase leading up the other...

"Oh my god!"

Scott rushed to the man lying on the floor in the room. He checked for a pulse already knowing the man was dead.

"He's dead."

"What seriously."

"Scott."

Taking the paper from Stiles he read it.

"No this is not true." Flinging it away he refused to believe it was true.

"We don't know anything yet Scott this guy could just be trying to blame..."

"Of course it's not true Stiles as if that could ever happen. There is no way it's true." Walking away he didn't see Stiles pocket the note nor pick up a recording device.

Fuming Scott just wanted out it was about time they called the Sheriff anyway.

The stairs led out in the pantry.

Scott could hear Erica and Boyd in the living room he and Stiles walked there.

"How long were we gone?" looking out the window it was already dark. Did they spend all day in the basement?

Erica was covered in blood and Boyd found one of the missing children. Their stories were horrifying. Erica was nearly killed and Boyd found all the kids but one horribly murdered.

Stiles was glad to hear that they talked to his dad who would be here soon. Less glad to hear that Allison was running around the house alone.

Scott may be in denial but Stiles already had the proof that Allison is the one behind everything. It's why he had Peter and Derek fake their deaths which everyone was in on from the start. Stiles needed Peter to use his contacts to investigate Allison. While Scott was in the dark bloody room Peter showed up and dropped off the paperwork he needed to confirm his suspicions. Scott never noticed that he lost the pillowcase when they left the kitchen. He gave it to Derek when Scott stormed off.

"We need to find Allison, Stiles can stay with the kid but if we split up we can find her faster."

"Scott is right I'll stay with the kid Boyd you take the top floor and Erica the second which leaves the first floor for Scott. Dad will be here soon so hurry." They couldn't let Allison get away. Those Argents have a bad problem of ignoring the psychopaths in their family.

Stiles hoped Allison could be stopped without lethal force. For Scott's sake if anything else.

Allison found Scott and convinced him that of course, it wasn't true. She was no killer how could anyone believe she could ever hurt a child.

Together they found Erica up stairs.

Erica asked why she ran off when Boyd entered the room. Allison said she was sorry but she was worried about Scott and wanted to find him which she did.

Allison had a plan to follow and some werewolf bitch wasn't going to interfere. She already dealt with the idiot who thought he could tell her what to do. Her grandfather gave him to her years ago and the bastard thought he had the right to stop her he forgot that she is the Master and him her servant. So-called humans born from animals have no rights. He should have been thankful to still be alive till now.

Smiling she blew wolfsbane into their faces then ran upstairs to find Boyd. She never wanted to give up Scott just yet. His death was going to put the Hale fire to shame.

She supposed it wasn't meant to be.

Surprising Boyd, she stabbed him then ran back to the front door. The wolves would die a slow and painful death she just wished she could have seen it.

The door was locked. How could this be it shouldn't... It wouldn't break. She tries the nearby windows.

"No this is impossible I killed you. You can't keep me in here you fucking bastard." The basement has a way out. Quickly she runs only to find the door locked like the front. Trapped she remembers that Stiles is also inside the house. That's why she couldn't leave there was still one more person alive.

Cautiously she moved through the first floor unlike the others Stiles was smart he didn't trust easily. Being the son of the Sheriff he was trained to think out of the box and survive. He acted like a spaz luring people into dropping their guard and then going in for the kill. Lydia told her about what he did to Jackson when they were kids. No one could prove that it was him but everyone knew it was.

Yes, Stiles would be the true challenge to defeat. Too bad he was so loyal to Scott otherwise she would have recruited him into the family. His viciousness would complement the family well.

Slowly she checked each room but couldn't find him. Going upstairs she couldn't find Scott and Erica they were missing. Running to the third floor she found Boyd was also missing.

Could they have left the house?

Running back to the front door she opened it.

Erica quickly took out the med kit that Stiles gave her and used the anti wolfsbane Deaton showed Stiles how to make. This wouldn't heal them completely but enough that they would be able to make it to Deatons in time. Treating herself then Scott, Erica quickly but quietly played dead as Allison ran through the hallway. Quietly they walked up the stairs.

Boyd had fallen close to the stairs he must have heard them and was on his way to help. Together she and Scott pushed him out of the window. They needed to get him to Deaton quick.

"Erica!"

"Derek! Boyd's been stabbed."

"Deaton!"

Derek watched as the three of them were led away by Deaton to be treated.

Stiles and the child were already out of the house only Allison was still inside. Derek really thought she was different that like Chris she wasn't psycho like her aunt. He should have known better all the Argent woman were crazy. Gerard didn't count he married within the family.

"Come, nephew, the pack needs us."

"Okay."

Chris didn't believe the Sheriff till he showed him the evidence. Victoria trained their daughter to meticulously target children. Knowing his father he helped her to refine the skill.

He raised Allison to be a kind yet cautious person he never once thought she would or even could do the things she has.

Chris waited with the Sheriff in front of the house. Stiles explained everything that happened inside. From Boyd finding the child and what was left of the other kids to the dead man in the secret room behind the pantry. He left a lot out both men could tell but knew it had to do with the supernatural.

It all happened so quick when Allison left the house. Chris was just thankful she was still alive. Eichen house would give her the help she needs.
