Sonic, Amy and Knuckles still continued to search for Shadow, but no matter what, they still couldn't find him.

"Perhaps he left the house." Knuckles suggested.

"Well if he did, what would he do?" Sonic asked.

"Wait, what if we search his room?" Amy suggested.

"Oh, come on! How come we didn't think of that earlier?" Sonic said frustratedly.

"Ok ok! Calm down!" Amy said quickly.

"Let's just go." Knuckles said.

The three went up to the first floor and searched for Shadow's room, Sonic went into his room and noticed Amy's diary sticking out.

Sonic breathed in heavily, then slowly breathed through his nose. "No, not happening."

Sonic closed the door and turned only to face Amy.

"Did you find anything?"

"No, didn't find anything." Sonic replied.

"Did you even bother to search?" Amy asked.

"Yeah I did, still couldn't find anything." Sonic said.

"Hey guys! I found it!" Knuckles shouted.

"Let's go." Sonic said.

Amy followed him to where Knuckles is currently at.

Knuckles was in the room and was checking Shadow's bag, which contained only the handcuffs. "This gives us nothing!"

"There has to be something." Sonic said and searched the bag and pulled out a notepad.

"What's that?" Knuckles asked.

"Notepad." Sonic opened the notepad and began to read what was in it.

It had a clean, almost polished handwriting in it.

'I am moving one step closer to my goal.'

'It was not my intention to poison Rouge, but it was random therefore I could not stop, Sonic, Amy and Knuckles know the truth, but however, Rouge and Tails are dead.'

"Does it mention Sticks?" Amy asked.

'Before the bombs went off, I was able to capture the crazy badger, but however they didn't notice the crack in the wall, but Sticks was making to much noise, so I had to silence her, knife to the forehead did the job perfectly (still have to clean up the mess though), though I had planned to have her lure the others into traps.'

"Damn it!" Sonic said.

'I've planned the next kill, hang someone, hopefully red-head. I will try and drag him to the third floor then have the plan go into action. I still don't know why I'm just using different techniques to kill my 'friends' but it will strike terror into their hearts, making them vulnerable '

"I've got an idea." Sonic said.

"What?" Knuckles asked.

"Does it involve us going into the third floor?" Amy guessed.

"You betcha." Sonic said.

(Later)

Knuckles was walking around the mansion when he heard a creak behind him. "I know you're there Shadow!"

Suddenly Knuckles got dragged from behind.

"Gah! Get off me!" Knuckles shouted.

(Elsewhere)

Sonic and Amy were on the third floor, behind boxes and beds and could hear the screams.

"Going well." Sonic said.

"If this goes well, our nightmare is over." Amy said.

Just then they heard the door open.

"Shh." Sonic whispered.

The killer threw Knuckles to the floor and removed his mask.

"I knew it!" Knuckles shouted.

"Too obvious? I thought it was easy."

"You killed our friends, why Shadow?" Knuckles shouted.

"Well, to put it in a simple way." Shadow said.

(Flashback)

'I never intended for Rouge to be killed by the poison, but it had to be someone.'

Shadow is seen placing the rat poison within the pizza, then he merged it with the food and then ran away.

'I thought I would've killed Tails, but the thing is...he knew too much.'

Tails is seen watching Shadow dump Rouge's body outside one of the windows.

He quickly fled, not getting Shadow's attention.

'And Sticks? Well, let's just say she had other plans.'

Shadow is seen placing his ear on Stick's bedroom door and heard her muttering.

"I know Shadow's the killer, once I find him, I'll tear his neck out!"

Shadow left and went into the basement to set up the bombs.

(End of flashback)

"You killed them for your own reason!" Knuckles shouted.

Shadow curb stomped Knuckles' head, then whacked him with a rusty pipe three times, then moved behind him to grab a chain.

"Now, four down, two to go." Shadow said. "Any last words?"

"Now!" Knuckles shouted.

Amy jumped from behind and whacked Shadow with her piko hammer. "HYAA!"

Shadow got knocked back into a wall as Sonic came out and Knuckles got back up in a fighting position.

Shadow quickly dashed at the trio and launched them back, causing them to make a triangle with Shadow in the middle.

"Do you really think you can get away with this?" Sonic asked.

"Always." Shadow said.

Knuckles tried to do a roundhouse kick on Shadow but he caught his foot and flipped him on his back.

Amy and Sonic attacked Shadow.

Shadow knocked away Amy's hammer, but then she punched him in the face. "GAH!"

Sonic did a bolley kick (Search it up) at Shadow and hit him in the chest, knocking him back a bit.

"Alright then." Shadow took out his pistol and aimed it at Amy and Sonic. "Stay right there."

What he failed to realize is that Knuckles is behind him and he tried to grab the gun.

They struggled for a bit, even causing the gun to go off at some points, but it ended when Shadow pushed him away and shot Knuckles six times in the chest, then shot him in the head.

"No!" Amy shouted and rushed Shadow, but he delivered a hard punch to her and threw her into a wall, knocking her out.

"GRAAA!" Sonic tackled Shadow down, causing the gun to be thrown away.

Sonic gave hard punches to Shadow's head, which broke his nose.

Shadow tried to stop him, but he was pulled up and knocked down, over and over again, until Sonic attempted to wrap the chain around his neck, but ended up getting his wrist, but he still locked it.

"No!" Shadow shouted.

"Too late!" Sonic continued to knock him down, before the floor started to creak.

"Stop! You're going to kill us both!" Shadow shouted.

"I don't care." Sonic said in a very dark voice.

The floor started to get weaker with every time Shadow got knocked down before eventually, the floor gave way and Sonic and Shadow both fell.

"AHH!" Sonic and Shadow screamed, but Sonic was able to grab the chandelier in the lobby, but Shadow was left dangling.

The chandelier's chain started to break, but Amy was able to wake up and grab Sonic just as the chandelier fell and broke into a lot of pieces.

Amy pulled Sonic up and they both looked at Shadow trying to get his wrist free.

"Break the chain." Amy said.

"Right." Sonic said.

"Wait! You need to listen to me!" Shadow called out, but Sonic didn't stop and break the chain by shooting it with Shadow's pistol.

"NOOOOO!" Shadow screamed as his body was impaled by the chandelier's sharp broken pieces of glass.

Pieces of glass had impaled Shadow's head, neck, left eye, legs chest, stomach and arms.

"That's for our friends." Amy said.

"Let's go." Sonic said.

Sonic and Amy left the third floor and went down to the lobby and saw Shadow's body.

Both let out a sigh of relief as their nightmare had ended.

"Let's leave this place." Amy said.

"Good idea, but what about the bodies?" Sonic asked.

"We'll bury them later." Amy said.

"Fair enough, let's get our stuff." Sonic said.

Both went upstairs and went into their rooms and packed their stuff.

"Wait should we get the other stuff?" Amy asked.

"Yeah, probably for the best." Sonic said.

Amy carried her bag and Sonic carried his, but Amy's diary fell out the bag.

Sonic picked it up and debated whether to give it to her or not.

He decided to keep it until later.

Sonic and Amy placed their bags in the lobby and went to get the other bags.

Sonic went and got Tails' and Knuckles' bag, while Amy got Shadow's.

Sonic went back to the lobby and went to get Sticks' and Rouge's bags.

He took out Amy's diary and debated again, but this time whether to read it or not.

Curiosity got the best of him and he opened the diary and began to read it.

'Dear diary,

Day 1, We just moved into Sonic's uncle's house for the weekend, should be great fun!

I even got to sleep with Sonic, nothing rude though.

But then something horrible happened, Rouge was sick after eating the dinner and then she died, just completely out of nowhere.'

'Day 2, I tried to calm myself down, but that night is possibly the worst day ever! I mean, one of my friends was killed! Well, that's what Shadow thought at least, though I never trusted him since the beginning, I didn't want to mention it because I thought I would've been next to be killed.

But I was wrong, Tails ended up getting killed and then the guy just ran away.'

There was nothing for day 3.

Then Sonic heard a noise coming from upstairs.

With Amy as soon as she had finished packing Shadow's bag she tripped and fell backward, hitting the wall, causing another notepad to be dropped in front of her.

She opened it and saw scribbly but readable handwriting.

"This isn't the same."

'The bat-girl died from the poison, it was not my intention to kill her off first, but when you have a table with seven people on it and hand them out plates, one of which had the poison on it, it will just be luck, to see who would die first.'

'I had convinced someone to help me with my job, she complied well, for a little while after she killed the fox boy.'

'We knew that she was the next one to go, I mean she even tried to leave the house at one point, but I stopped her just in time.'

Amy's eyes widened as she read every word on the notepad.

'Shadow attempted to kidnap the badger in order for her to work for us again, but he killed her, despite my requests.

Oh, I nearly forgot, I also convinced Shadow to help me, after he left Sonic in a room, he killed Sticks by stabbing her in the forehead, it was a gruesome sight, blood was dripping down and then he went mad and pulled out her tongue and cut open her chest. That was when we knew he had to be killed.'

"Are you sure you should be reading that?"

Amy screamed as a person in a black cloak and mask appeared to her left.

She got up and headed for the door, she was able to get out, but then felt a sharp pain in her back and someone covering her mouth.

Amy fell down and saw Sonic standing above her.

"Sorry, Amy."

"No!" Amy shouted, but Sonic plunged the knife deep into her head.

"Brilliant Sonic!" the killer shouted.

"Thank you, Chuck." Sonic said. "Now what?"

"I'll let you decide." Chuck said removing the mask.

"Hmm, I think I've got the right idea." Sonic thought.

Sonic carried Amy's body down into the basement, the door closed behind him.

The end.

Sorry for the anti-climatic ending, I did plan for a fifth chapter, but I ran into a lot of difficulites, so I just gave up. Sorry.

So was anyone expecting the twist?
