A/N : Thanks very much to those reviewing. I'm glad that people are liking the start of this and that I'm succeeding in my goal of writing a story like an episode. Off on a trip on the weekend and I'm not sure of the Wi-Fi where I'll be staying so I'll put out two chapters each day over the next couple of days to make up for the possible gap.

Disclaimer : Marlowe, ABC and the other writers of Castle own the show and characters. I just appreciate their work so much that I wanted to try and emulate them.

For the second time that morning Beckett and Castle enter the interrogation room to the sight of a suspect seated at the table waiting for them. Sorizo is a young, pale faced man with short brown hair plastered greasily on his head, still wearing the black hoddie he'd been caught in and looking uncomfortable in the brightly lit room.

"Paul Sorizo, twenty-four years old and college dropout from Cal Tech," reels off Beckett as she and Castle take their seats at the table opposite Sorizo. "So Paul, what were you doing at Sam Carmody's apartment?"

Sorizo nervously responds, "Sam was going to give me some money and we'd arranged to meet at his place."

"So when he wasn't there you broke in and tore the place apart looking for it?" asks Castle.

"No way. The door was open and the place was wrecked when I got there," replies Sorizo holding up his hands pleadingly.

"So why did you run when we arrived?" presses Beckett.

Sorizo looks to the side to side as if looking for a way to escape, "Look, I panicked OK! I hear cops and the place is trashed and I'm standing in the middle of it. I know how it looks so I had to get out of there."

Beckett gives her own spin on Sorizo's story, "Or after killing Sam this morning and not finding any money on him you went to his place to find it using his own key to get in."

"Wait, what, Sam's dead?" asks a shocked Sorizo.

"Shot and then crushed behind a dumpster two blocks from his apartment between 2 and 3 this morning. Where were you then Paul?" asks Beckett.

"I pulled an all-nighter playing Alpha Squad on-line. You can check my game account log."

"Except all that will show was that someone was using your screen name during that time, not necessarily you," discounts Castle with his own, first hand, knowledge of all night on-line gaming.

"Look, I had no reason to kill Sam. He's a college buddy. We were helping each other out," pleads Sorizo.

"Was that helping him looking for his sister Julie?" inquires Beckett as she opens the file in front of her, takes out a photo of a blond haired, striking looking young woman and places it in front of him.

Sorizo reaches out, takes the photo and studies the image, "Yeah, nine months ago he turned up in town and told me his sister had disappeared and needed my help. I'd moved out here a while ago so as I knew the city better he thought that I'd be able to help him."

"If he was such a good buddy, why then the two payments of five thousand dollars each during the last six months? Was that payment for some of your, let's say, less than legal computing skills?" asks Castle.

"We know you're on the FBI watch list for known hackers Paul," adds Beckett.

"Ok, Sam thought that there was info about his sister on some modelling agency websites and needed me to get into them for him. It's not like I was stealing bank account details. It was only some contact info and shooting schedules."

"Ten grand over six months seems a bit steep for that, especially for a guy working part time in a computer store. Plus, Sam was a Cal Tech computing student like you. Why couldn't he do that himself?" asks Castle with a look of incredulity.

"Sam was more into hardware and programing and you need some specific skills to get into sites unnoticed. The money was for some hardware purchases I needed at first and then as Sam learnt that I was having it rough out here he gave me the money to help me out. He still had some of his parent's life insurance money and he didn't mind sharing."

"Generous of him," returns Castle.

"Yeah well, Sam was like that plus he'd do anything to find out what happened to Julie," shrugged Sorizo.

"So did the info you obtain help? Did Sam have an idea of who might have taken his sister?" asks Beckett.

"He thought that some sleaze bag photographer might have had something to do with it."

"Michael Ferry?" suggests Castle.

"Yeah that's the guy. Sam found one of his flyers in Julie's stuff and he wanted some more proof that he knew Julie," responds Sorizo eagerly.

"We've spoken to him already. Besides the flyer did you find anything that linked Ferry to Julie's disappearance?" inquires Beckett.

"I don't know. Sam just asked me to get the info, he was the one putting it all together. He had it all on the computers at his place."

"Which had their hard drives taken when his place was trashed. Who would have done that Paul? Ferry?" persists Beckett.

"Yeah, sure. All I know was Sam was convinced that Julie's disappearance had something to do with her trying to become a model and that he thought that Ferry or someone else in that world had something to do with it."

"Someone else in that world, like who?" inquires Castle curiously cocking his head.

"I don't know, Sam said that Julie did get a few small jobs with the Martel agency before she disappeared and maybe they knew something. They were one of the agencies sites he had me, uh, access," responds Sorizo desperately as he realises that vague answers aren't helping him.

"We'll want a list of all the sites you accessed Paul," instructs Beckett with a look. Sorizo nods his assent at that.

Beckett takes another photo from the file, this one a blow-up of the tracking device taken from Sam's arm and asks, "What about this? Do you know what this is?"

A look of surprise and curiosity crosses Sorizo's face, "No idea. As I said, Sam was the hardware guy. Where did you find that?"

"Sorry Paul, you're here to answer questions, not us," rebukes Beckett.

"Before his death Sam spent about seven hours in the Hamilton Heights area. Any idea what he was doing there?" asks Castle quickly to keep Sorizo talking.

Sorizo looks surprised again at this question, "No idea. I hadn't seen Sam for about a couple of weeks and when I did I just spoke to him over the phone. I hated to ask but I need some more cash. He said he could let me have some more but it would take a week to get it together which was why I was at his place. Believe me, I had nothing to do with his death or know anything else about what happened to Julie," insists Sorizo looking back and forth between Beckett and Castle.
