Part 4. Brother.

Alfred sighed, walking towards the mayor's house. He ducked under the police tape and followed Kiku up the stairs, to the man's bedroom. If this was their killer again, then they'd gone too far. Alfred had to admit, the mayor had done some sleazy things, but nothing to deserve getting murdered like the others had been.

Alfred was surprised, though, when he walked into the room. There was…evidence. This killer never left evidence, but now there was a pile of clothing, bloody knives discarded on the ground, people looking at fingerprints on the walls.

"Holy shit," Alfred muttered. "Either he got lazy and we just hit the jackpot, or this isn't him."

"It's him," Kiku nodded gravely, looking towards the corpse that was being analyzed as well. Alfred was thankful he had his gloves on as he looked at the man's eyes, wide with terror, looking at a person that had long since left.

"Ludwig," Alfred called over to the other officer that had just been put in charge of this case. He was on the wall, examining fingerprints. "What do you have?"

"I don't think it's a he," Ludwig sighed and Alfred raised a brow. Sure, a chick could do this, but how could he tell from a finger print test? "It's a they."

"What?" Alfred asked, walking over to the tall man. He looked carefully at the swirls under the black light and saw that they were slightly different sets of finger prints. "Dammit."

"Why are they leaving evidence now?" Ludwig asked. "They might be crazier than we once thought."

"Like hell do I know," Alfred shook his head. "Check these prints, see if they're fake or even the same person. We'll also DNA the clothes to make sure they match up. And the knives. They left a lot of evidence this time. We'll catch 'em if it's the right kind."

"And if it's not?" Ludwig asked.

Alfred didn't answer, he just tore out of the room, pulling out his cell phone to glare at it. His brother hadn't called him in weeks, since a little after that new roommate came to his old apartment. He figured his brother was fine, but not hearing from him in so long made him worry.

Alfred leaned forward onto his palms on the desk in front of him, Ludwig standing beside him. He was staring at the computer screen in front of him that was loading the results. It was a damn slow computer and so Alfred hit it and the results finally came up. And Alfred's stomach dropped.

"No," Alfred shook his head, quickly looking through all of the reports. That one person's DNA was on all of the evidence they'd found. It had to be some kind of…trick or something. His brother's face was staring right back at him, right next to some albino guy with the same last name as Ludwig. "No."

Alfred pulled out his phone again and wasted no time in calling his brother.

"Should we be tracing this call?" Ludwig asked.

"My brother is not a murderer!" Alfred snapped, loud enough for the whole office around him to stop working for a few moments before returning to their work. "There's no need to trace anything!"

"Hello?" came the breathless reply on the other line. His brother was gasping and Alfred could only assume why.

"Mattie?" Alfred felt his voice crack, betraying him, but he had to stay strong.

"Oh," Matthew laughed, but let out a small groan of…pleasure? "H-hey, Al, what's up?"

"What are you…doing?" Alfred asked.

"Some guy." Came the reply, along with a laugh from his brother and another party. Alfred looked at the picture of the albino.

"Listen," Alfred muttered. "I got some new evidence from that serial killer." He winced at the loud groan from the other side. "All of the evidence points towards you."

"Wow, that was easier than I thought," Matthew laughed and Alfred hoped to God that he was more preoccupied with his other conversation. Alfred was weary over the fact that his brother was actually…so open and not shy, and he just prayed that Matthew was just going through a small rebellious phase or something. "It only took you guys less than a day to find it out, good job."

"You're not…" Alfred started breathing heavily as he heard the other man on the phone grunting. "Mattie, please don't tell me…"

"Is anyone missing those people, Al?" Matthew asked clearly and Alfred felt his heart drop. His own brother…He sounded so serious on the other end. "They were terrible people that didn't deserve to be alive anymore."

"That doesn't mean you just kill them!" Alfred roared. "They get justice eventually! They get arrested!"

"I watch the news," Matthew laughed darkly. "Every day because of my OCD." Alfred nodded, he knew about his brother's OCD, especially after he got attacked with a hockey stick for trying to touch the pancakes before they were done cooking. "They weren't gonna get arrested. I'm not either. Tell that to Arthur Kirkland, evening news."

"Mattie," Alfred was at a loss for words. His own brother…a cold hearted murderer? That innocent little kid he'd known for his whole life that would never hurt a fly unless he got really pissed off? "Please, I-I can get you help or something. This…this isn't healthy. Please. Don't-"

"You're not even tracing this call are you?" Matthew scoffed. "Whatever, I'm long gone now. And I don't need help. There's nothing wrong with me. I just see the evil of this world and I get rid of it. Gilbert, too. You just don't understand."

"Now, we would like to get back to fucking in peace," the other man cackled on the other end and hung up. Alfred's jaw stayed slack and Ludwig stared at him in concern. Alfred yelled out in anger, punching at the metal desk below him and not thinking much about the pain afterwards.

"Was Gilbert with him?" Ludwig asked carefully.

"Yes," Alfred whispered.

"Was there anything we could use in that phone call to find out where they are?" Ludwig asked.

"I didn't hear anything," Alfred shook his head. "Am I stupid? Is that why I didn't notice my own brother going crazy?"

"It happened to my bruder, too," Ludwig said seriously, though Alfred could see the hurt mirrored in Ludwig's eyes. "All we can hope is to get them to justice and get them the help they need. We will catch them, do not worry."

"My brother is an insane murderer and you're telling me not to worry?" Alfred hissed, unable to get his voice to be very loud. "Are there signs? Should I have been looking harder?"

"There's nothing you could have done," Ludwig assured him, though Alfred noticed that his hands were shaking. "Neither of us could have stopped something as serious as this. They will be caught, we will find out what is wrong with them, and the justice system will do what it will for what they have done. That is all we can do for them."

"I became a police officer to help people, to be a hero," Alfred sighed, running a hand through his hair. "Not to chase after my insane brother after learning he's killed several people."

"It's what we have to do," Ludwig said, clearing his throat, before he walked further into the room to talk with a few other men. Alfred shakily looked over at the photographs of his brother and Gilbert, staring at them. They looked normal enough, but he couldn't help but wonder what his brother looked like now. After he'd killed innocent people.

"I'm going to bring you to justice, Mattie," Alfred muttered, glaring at the electronic picture. "And I'm gonna get you help. I know you're not insane. I know we can get through this together. We'll just work hard and pull through."

Sadly, though, the madness descended upon Gilbert and Matthew sooner than anyone expected. The next time anyone saw them, it was dead in each other's arms, throats slit by each other's knives.

My God, I did not expect this ending to happen. Long story short, I was watching "Law and Order Special Victim's Unit" and that never has a happy ending, so I guess that inspired this one. Yes, this fic was inspired by that show, don't ask me how, it just happened. And it unfolded into a beautiful madness I can't even explain. I swear guys, I'm not this insane.

In any case, please review, tell me what you thought of this whole thing. And have a very happy Halloween, even if you don't celebrate it!

And I do not own Hetalia.
