A/N: Hi guys. Eleventh chapter is up! Yay! *Sighs* Sorry, I'm not as talkative right now. Anyway, let's just start the chapter before you guys start getting annoyed at me.

"Ames?" Jake Rosenbloom knocked on the mentioned girl's door, worried. It had been two hours, and she still had not returned. Dan and everyone else had 'elected' him to go speak to her.

XxXxXx

"She's your girlfriend!" Dan argued.

"But you are her brother! You went through the Clue Hunt and the Vespers together!" Jake protested.

"But still, she kissed you! The only thing she's ever done was hug me." Dan glared.

"I vote Jake." Ian interrupted.

"Same." Hamilton and Sinead nodded.

"Seems logical." Reagan and Ned added.

"Seriously, now you guys are ganging up on me!" Jake whined.

"Jake, just do it." Atticus groaned.

"Fine." Jake relented, starting to walk up the stairs. Wish me luck. He thought.

XxXxXx

"Go away." came the muffled voice of his girlfriend.

"Amy, please come out. We can't solve this without you." Jake begged. "We're sorry we were arguing, everyone was just upset that another person died."

"That's no excuse." Amy replied bitterly. The girl got up, walking over to the door and sliding down to sit with her back against it.

Jake did the same, sighing as he looked up at the roof. "I'm really sorry. Everyone else is to." He murmured.

It took a bit for a reply to come. "…I forgive you, and everyone else."

Jake cheered inwardly, Victory! he thought. "Are you coming out now?" The boy stood, backing away from the door.

The knob turned, the door swinging open to reveal a certain auburn haired leader of the Madrigal branch.

Jake smiled, hugging his girlfriend as he buried his nose in her hair, taking in her scent. "Let's go down." He suggested, pulling away and taking her hand in his.

Amy nodded, starting to pull him along as she trotted down the stairs carefully, clutching the rails for extra safety.

XxXxXx

"We're sorry, Amy!" Chorused the group as Amy and Jake entered the room, hand in hand.

The girl smiled. "I forgive you guys. Just don't do it again, or else." She glared.

The rest of the people nodded vigorously, starting to sit on the chairs and couches.

"Hamilton, did you see anything on Madison's body that was unusual?" Amy asked, getting straight to the point.

The Holt shook his head. "I just found her like that, unmoving. It looked like she was asleep." He answered.

"I saw something." Reagan offered.

"Mind you tell us what?" Ian asked.

The girl nodded, starting to speak. "When I was kneeling by her bed, I saw a small puncture hole at the base of her neck, like someone poked wanted to put something in there."

Sinead frowned in thought. "Why didn't you mention this before?"

"Well I didn't want to…to…" Regan searched for the word she was looking for, it was on the tip of her tongue.

"Alarm people?" Ned offered.

"Yeah, that."

"How big was the hole?" Amy asked.

"It was small, about the size of the tip of a sharpened pencil."

"I think that the hole could have come from a sharp needle, or a dart gun. Most likely the killer injected some kind of poison into her blood stream." Sinead concluded after a few moments of thoughtful silence.

"I agree with Sinead." Dan spoke.

Atticus nodded. "It seems like the most logical conclusion."

"Then the killer is someone who most likely uses needles, or darts." Amy said.

"Irina used needles, didn't she? They were on her nails and laced with poison." Natalie suggested.

"But Irina is dead." Dan reminded the girl. "Even if she was alive, she wouldn't kill anyone. She was a good guy!"

"Dan's right." Amy backed up her brother.

"Wait…I know someone else who uses darts." Dan came to a realization, the young Madrigal backed away from his spot near Natalie.

"Dan? What's wrong?" Sinead asked, everyone else in the room stared at him.

"It was you, wasn't it?" Dam whispered, pointing at Natalie.

"I don't know what you're talking about." The girl replied simply.

"Cut the crap! You're the killer aren't you?!" Dan shouted.

The British girl stood, sighing as she pulled out her dart gun. "I really wished you could have just kept quiet, Daniel."

The rest of the room backed away immediately, realizing what was going on.

"Natalie? You're the killer?" Ian asked, disbelief shone in his eyes. "Why? Why would you kill them?"

"Why? WHY?!" Natalie replied, a malicious grin spreading across her lips. "I killed them! Because I should have gotten the serum! I should have been the one to have the power! Not Mother! ME! ME!" Natalie shrieked as she pointed her dart gun at Amy.

"Natalie, stop this." Ian demanded.

"Ian, I did not mean to stab you, for that I am very sorry. The one I wanted to stab was Amy. Or her little boyfriend Jake." The girl sneered.

"So that's why there was a gasp…" Amy whispered.

Natalie nodded curtly, standing on the separate side of the room, nearest to the door as the rest of the Cahills stood on the other side.

"Natalie, stop. This isn't going to change anything." Ian said, starting to walk towards his sister.

"One step closer and Daniel gets shot. He'll die within a week if you don't get the cure, which only I have." Natalie said, swiveling her dart gun to point at the surprised teen.

Ian immediately stopped. As much as he despised his distant relative, he didn't want him dead.

"Good." Natalie started backing away, her weapon still pointed at a frozen Dan. The rich girl kept one hand on her gun, another reached for the doorknob as she fumbled slightly. Finally, she opened the door, starting to step out.

"Natalie don't do this." Amy whispered as the girl slowly stepped out.

"Oh Amy, I already did." And then she pulled the trigger.

"DAN!" Amy shrieked, the world seemingly slowed down. The girl could only watch as the dart flew towards her brother.

"No!" Amy's head turned, hearing Ian yell and start running towards Dan.

And then the world went back to normal.

XxXxXx

Dan stood there, shocked as Ian was hit by the poisonous dart. "Why?" He whispered. "Why would you do that?! You idiot!" He shouted, catching Ian as the boy fell to the floor, the poison already taking effect.

"As much as I absolutely hate you, Daniel, I do not wish to see you die because of my sister's actions." Ian murmured, the room starting to spin.

And then the world went black, and Ian knew nothing but darkness.

XxXxXx
