Castle's phone went off right next to his ear. He groaned, still half asleep. Beckett was calling. He answered wearily.

"Yes?"
"We've got a case. You want in?"

Half an hour later, armed with coffee, Castle was sitting by Beckett's desk.

"So, what happened?" he asked.

"Someone bombed an alley. No-one was harmed. We're trying to work out why it was bombed."

"Any suspects?"
"None yet. Esposito's talking to someone who was nearby at the time." Esposito walked in at this point.

"Talk of the devil." Castle said.

"So get this. Apparently, our mystery bomber is a teenager. The person I just talked to wouldn't say how they knew this, but the teen's name is Julius Grief."

"You know, that is the perfect name for a bad guy. You've got your historic figure of power, and almost a promise of what they're going to cause you." Esposito and Beckett looked at him. "What? You have to admire something like that." Ryan walked in.

"I found out something too. I know where Julius Grief is."

"Someone matching his description was seen entering a nearby building. Apparently, he rents the flat on the fourth floor."

Alex was relaxing in a flat in America. He was sent out there to foil SCORPIA's plans (yet again). For some reason, they were bombing areas of New York. All Alex had to do was stop it happening, and try and find out why they were doing it. It was 'simple'. Alex snorted. It was SCORPIA. When was anything ever simple with them? Suddenly, the door crashed open and people started yelling incomprehensible words. Instinctively, Alex dived for the gun, which was on the coffee table for some reason (Did he forget to hide it again?), and rolled into a standing position, to see 4 police... no, wait 3 police officers and a writer? Alex groaned when he realised the police had guns pointed at him. He dropped the gun he was holding, and placed his hands in the air. His hands were yanked forcefully behind his back. He heard a voice coming from behind him.

"Julius Grief, you are under arrest for suspicion of being involved with terrorists." Alex was stunned. Who were these people? More importantly, why did they think he was Julius?

Beckett walked in the interrogation room, Castle following behind her. The teenager looked up at their entrance. Beckett matched the blank mask on the teen's face with one of her own. She sat down, and folded her hands together.

"So, Julius, tell us why you were near the and what you were doing there." Alex quirked an eyebrow.
"I'm afraid you've got the wrong person." he said.
"What do you mean?"
"I'm not Julius Grief."

"And why should I believe that?"

"Because it's the truth." Alex folded his arms.

"We've got people telling us you are." Alex's eyebrows shot up. Well, that was unexpected. What was SCORPIA's plan with this? They were the only people that knew about Julius... Unless it was one of his 'siblings' out for revenge...

"They're misinformed." The conversation went on like that for a minute or so more.

"So you're not Julius." Beckett finally said. Alex relaxed slightly. "But you do know him?"
"...You could say that."
"Okay. So what do you know of him?" Beckett asked, leaning forwards.
"Plenty of things. I know his face, his parentage, his schooling, and the most important fact of all." Alex said with a smirk.
"What is it? Is he a spy? An assassin? Son of a Mafia boss?" Castle asked quickly. Alex shook his head.
"No. Well... Never mind. The most important fact is-" Alex was cut off by the door to the room opening. Esposito stood there with a file in his hand.
"Beckett. Important information. Can't wait." She stood up with a sigh.
"Castle, come with me. You, stay here." Alex put on his best innocent look.

"What is it? He was about to tell us something important!" Castle (almost) whined.
"This is more important. This file is from the CIA. It says here Julius Grief is dead. Shot by an MI6 agent after trying to assassinate the American Secretary of State. That kid in there is not him. But get this." Esposito pulled out a photo.
"They're twins!" Castle explained.
"Well, let's find out exactly who we've got in there then." Beckett said, walking back to the interrogation room. It was empty. Everyone stared at the handcuffs and note that was on the table. Castle picked the note up, opened it, caught the disfigured paper-clip that fell out and laughed.
"This kid has style." he said, still chortling slightly. He turned the note round so the rest could see it. There was one word written hastily on the paper.

Sorry.
