This is my second attempt at a CSI fanfiction (I've been obsessed lately, and this idea's been stewing for a while). I make allusions to some things in this story, and i'll try to explain them at the end of the chapters for those of you who won't get it. Well, enjoy guys and please drop a review if you have something to say.

Disclaimer: The usual: I don't own any of the characters that you recognize.

Warnings: Some of this will get kinda grahpic, but thats what the ratings for. There are a couple minor spoilers and major spoilers for Grave Danger Part One and Two.

A/N: I'm not much of a fan of CSI romance and didn't intentionally put any in this fic, but you can interpret my writing however you like.

Chapter 1

Brass and his team were already there, the lights of the police cars flashing brightly across the front lawn. A sobbing woman and shocked looking man, presumably the parents, were standing outside the caution tape, looking horrified. The neighborhood was a wealthy place: big houses, big lawns, and sometimes, a big backyard. This house was no different than the others around it. It probably had just as many security systems as was typical for such well-to-do people. There was no doubt about it. This guy knew what he was doing.

Nick got out of the car, almost immediately being ambushed by Brass. "Where's Grissom?"

"Good evening to you too, Jim," Nick replied, taking his kit out. Brass raised his eyebrows at him expectantly. "He'll be here soon."

Sara joined them. "What have we got?"

Brass looked at her. "Girl's in her bedroom. Apparently, the parents got home to check on her and she was dead."

Nick looked up at the house. "Is it clear?"

Brass nodded.

"C'mon," Nick grabbed his case and ducked under the tape. "After you," He said, holding the door ajar for Sara.

"Upstairs?" Sara asked an officer, who nodded back at her. They headed for the stairs. "Think it's our serial killer?" Sara asked.

"They would have told us if they saw a similarity between this one and the others." Nick replied, pushing the girl's door open. "Might be, though. She's the right age," He glanced at the teenager lying in her tangle of bloodstained sheets. "I'll photograph?"

Sara nodded, looking disgusted when she saw the corpse. The girl appeared to be about 17 and her hands were tied to either bed post. From what Nick could see, she'd been stabbed somewhere near the stomach. He shook his head and started taking pictures. "Window's open," Sara said.

Nick examined the lock on the window sill. "No sign of forced entry. Not much disturbance. She was probably sleeping when he entered."

"Looks like she put up a fight, though." Sara was bent over the girl, turning over her hands.

"Hey guys," Nick looked up and saw Grissom in the doorway.

"Hey Gris," He answered, going back to his photographing. Behind him, he heard Grissom going about his usual antics at a crime scene. The room was in pristine order, just like all the other cases. There was little sign of struggle, if none. The messiness of the room was probably just due to the fact that it was the bedroom of a teenager, Nick thought. Perhaps a couple things were out of place on the bedside table, but other than that, the room was clean. Nick was willing to bet his life that Sara would find no prints either. They were back to where they started with the other three murders. He wandered over to the bedside table.

There was a lamp, some papers, a cell phone and a book. Nick took pictures, though doubting that they would need them. Out of interest, he turned the book over. He raised his eyebrows and looked back at the girl's body. What a coincidence. But Nick's job had trained him to not believe in coincidences. "Hey Grissom," He said. Grissom looked up from what he was doing. "What would you say our vic died of?" Nick asked.

Grissom looked at him before glancing down at the girl. "Well, we can't know until the autopsy, but… wait." He bent down and examined the girl's middle. "From what it looks like here… the knife would have missed her heart, probably nicking her stomach… death from poisoning by stomach acids?" Grissom looked back up at him. "Why?"

Nick held the book up. "The Da Vinci Code. Our serial killer has a sick sense of humor."

Okay, for those of you who haven't read Da Vinci Code, one of the "main" characters dies this way, but you find that out in the beginning so i'm not spoiling it for anyone intending to read that book.

Thanks for reading! Tell me what you think... Next chapter will be up sometime soon depending on what my humongous load of homework will allow, but If I get some comments I might be inspired to post sooner (wink wink).
