Catherine knocked on the door to Grissom's office.

Grissom looked up for an instant from a report he was doing.

"Come in Catherine."

"Gil, what's this case with the kid and the decapitated mom all about?"

Grissom smiled sadly. "Wish I knew."

"You know this case is sort that just ticks me off, why do cons insist on playing games with us, they should know by now how the rules go: They do the dirty, we find the evidence to pin them, they go to prison."

"If only it were that simple all the time", Grissom mused.

"Whoever did this, scared that kid into telling a whole bunch of cryptic lies…"

Grissom interrupted her. "I'm not so sure they're lies… I think they're clues. You're right Catherine, sometimes criminals do just want to play a game. But sometimes they also accept that they're going to get caught sooner or later… sometimes that's what they want, it gives them more of a rush. I think this guy wants to see us squirm and keep us up nights thinking about what he's done and trying to catch him."

Catherine shook her head. "But why?"

Grissom shrugged. "Because he's a murderer… and he plays by his rules."

Catherine stood from her chair. "I'm going to go see if CODIS has kicked anything out from our fingernail scrapings, see you later Gil."

"Bye."

Catherine paused when she arrived at the door to the break room, staring at the man sitting at the table inside, with his head in his hands.

She walked in slowly at touched him gently on the shoulder.

Warrick jumped slightly in surprise at Catherine's touch.

"Oh hey Cath."

"Hey yourself. How you doing, I hear you've got a pretty tough case going at the moment."

Warrick nodded. "Yeah, I won't lie and say it's not bothering me."

"Kid shows up with an envelope with your name on it? Does this possibly have something to do with some skeletons hanging in your closet?"

Warrick sighed and look and Catherine in the eyes. "I really don't know Catherine. I wish I did."

"Well, I've got some DNA results here from the nail scrapings from your vic."

Warrick's eyebrows lifted, interested. "Hit me."

Catherine chuckled bitterly. "You know it's funny you should say that."

Warrick looked confused. "Why?"

Catherine read from the piece of paper she was holding. "DNA belongs to one Tool Attola-Debbor."

Catherine slid the page over to Warrick, but he didn't have to look at it, he knew who this man was.

His wide eyes met with Catherine's.

"Loan Shark."
