Because Stiles was unable to focus on his job he took a few days off work. It was 11:47 Tuesday morning and he was in the kitchen cleaning the dishes that Derek forgot to do last night. He stopped and looked around when he heard footsteps. He didn't see anything so he went back to cleaning the dishes. When he heard more footsteps he turned around so fast the he dropped one of the glass plates. Taking a few deep breaths he knelt down and started picking up the shattered glass. The noises didn't stop and he ended up cutting his hand on a piece of glass. He cursed and grabbed a washrag, wrapping it around his hand he grabbed his keys and left the house.

Later that day when Derek came home he expected Stiles to be there but he wasn't. When he went to the kitchen he saw the blood and he called Stiles.

"Hey Derek." Stiles said.

"Where are you?" Derek said. "Are you okay?"

"I'm fine." Stiles said. "I dropped a plate and ended up cutting my hand. I'm okay but I had to get stitches. I'm waiting for the doctor to come back now."

"Okay I'm on my way there." Derek said heading for the door.

"No." Stiles said. ""Allison is picking up the kids from school and I told her that you would be home. Just clean up the glass and I'll be home as soon as I can."

"Alright." Derek said. "I'll see you when you get home."

That night

Derek was sitting outside on the steps waiting for Stiles. Ashley and Logan were already asleep. He stood up when Stiles pulled into the driveway.

Stiles turned off the car and headed over to Derek. "Hey where are the kids?"

"Sleep." Derek said taking his hand. "What happened?"

Stiles looked at Mark's house then back at Derek. "I kept hearing stuff in the house. Like thumping and footsteps in the house and it kept freaking me out. "I think someone was in the house."

"Stiles that's not possible." Derek said. "I changed the locks and made sure to lock up when I left. Maybe you're just hearing things because you've been having problems sleeping."

"I'm not crazy Derek." Stiles said. "And I'm not seeing or hearing anything. Someone was in the house with me, I know it." He walked past Derek and into the house.

Derek looked around the dark streets before going back inside. Not knowing that Mark was close by listening to their whole conversation.

The next day

Stiles was on his laptop in his room. He was looking up stuff on the internet when his phone rang. "Hey Derek you'll never guess what I found on the internet."

"It's good to hear you too." Derek said. "What's going on there?"

"Did you know that a family was killed in this house a year ago?" Stiles said. "They had three kids too."

"Are you serious?" Derek said.

"Yes." Stiles said. "You didn't know any of that when you bought the house?"

"No I didn't." Derek said. "If I had known that I never would have bought this house. What else does it say about the house?"

"No one has lived here since it happened." Stiles said. "Why didn't he tell you any of this?"

"I'm guessing because he wanted me to buy the house." Derek said. "Does it say anything about who did it?"

Stiles scanned down the page. "It says the next door neighbor was the lead suspect but they couldn't find anything to prove that he had anything to do with it so he was cleared. They still don't know who did it."

"What was his name?" Derek asked.

"Sage Henderson." Stiles said. "I'm trying to find a picture of him now." He sighed a few seconds later. "I can't find a picture but what do you think happened to him. I mean if I was him I would move as far from this place as I could. I mean would you stay here if you were him?"

"I would leave." Derek said.

"Do you think Mark would know anything about this?" Stiles said. "I mean he's living in the same house so he must know something right."

"Don't you dare go over there asking him questions?" Derek said.

"Are you insane I'm not going over there?" Stiles said. "He already freaks me out."

Derek sighed. "Look Stiles please don't go snooping around outside. I'll talk to the guy about the house and the next door neighbor and see if I can find anything."

"Fine, I'll let you handle it." Stiles said. After hanging up the phone with Derek he continued look up stuff about the murder that took place a year ago. He knew Derek would be upset if he found out but he couldn't let it go. A while later he was interrupted by the door. Going downstairs he answered it without thinking. "Mark?" He said.

"Hi Stiles." Mark said. "I'm sorry to bother you but I seemed to have misplaced my house key. May I use your phone to call a friend of mine, he has my spare key."

"Um okay." Stiles let Mark in and looked around. There were some people outside and they were staring at him. He went back inside and handed Mark the phone.

"Thanks." Mark said taking the phone. "Can I use your restroom?"

"Sure it's upstairs and the first door on your right." What the hell was he doing? Stiles thought to himself as Mark made his way upstairs. He paced back and forth as he waited. Minutes past since he heard anything then Mark came back into view. He stepped back as Mark made his way downstairs. "Did you find everything okay?"

"Yes I did." Mark said handing Stiles the cordless phone. "Thank you." He said leaving the house.

Stiles made sure to lock the door before going back upstairs. He stopped by the bathroom and saw that nothing was out of place. It was like no one had used it. When he went back to his room he could tell that someone was on his laptop. Going over to the window he saw Mark leaning on his car on what looked like a cell phone. He watched him until Mark got in his car and drive off. He still saw people staring at the house from across the street. Going outside he walked over to them. "Excuse me um can I ask you guys a question?"

"You shouldn't let him in your house." She said. "I've lived here for almost five years and I've never talked to him. Ever since that family was murdered this whole neighborhood has been terrified."

"No one knows who it was?" Stiles said.

"No but that man has lived alone in that house ever since I moved in." She said. "As soon as moved in everyone told me to stay away from him. You should do the same." She walked off.

Stiles watched her go back into her house then headed back to his house. He went back to searching on his laptop and not long later he found a picture of the suspect and it was Mark. He was the suspect in the murder case, Sage Henderson.
