Kate Beckett walked up to the smouldering building, her constant shadow two steps behind her. The fire had just been put out, and in the wreckage, the firefighters had found a body that looked to have been tied up just inside the and called it in. Walking up to Lanie, she she didn't even have to ask what was going on before the M.E. was off.

"Girl, don't even ask, i have no idea. There isn't much left of whoever this is. I wont be able to make any sort of id until i get back to the morgue."

"Male, 45-55, fat" Castle piped up with just a cursory glance at the bones that were left, causing both Kate and Lanie to look up at him like he was crazy.

"Ooookaaayyy...anyways, I'll let you know what i know when i find out." Lanie said, completely dismissing Castle's comment. Just as the small group was breaking up, there came a shout from further within the building.

"Beckett! You might want to get in here!" Ryan called from deeper within the mostly ruined building, "we've got more bodies!"

This statement cause all three of them to turn and head into where Ryan and Esposito were standing in what had been a door frame that entered into a large open room. Coming to stand just beside them, the group looked at the chaos within. Hanging from the ceiling in a circle was twelve chain nooses, some still had mostly burned bodies hanging from them, and where there weren't bodies, there was a pile of bones and burnt flesh. Beckett let out a swear, Lanie stood gaping, and Castle was walking toward the body that was closest and on the floor while pulling a pair of gloves out of his pocket.

"Hey! Castle, what the hell are you..."

"Beckett, don't ask until I can tell you more" he said cutting her off and throwing a steely look over his shoulder. He continued moving towards the body, bending down when he reached it, still with the group of detectives standing behind him gaping. Reaching into the mess of bones and flesh, he found what he was looking for, and slowly ran his fingers along the upper part of the femur, closing his eyes when he felt the etching he had been looking for, but had prayed he wouldn't find. Lowering his head, he muttered a swear, a prayer, and then another swear. Retracting his hand, he looked behind him to see many different looks on his friends faces. Confusion, anger, surprise, and impatience. Standing up, walked towards Kate.

"What the hell are you doing Castle, you know your not suppose to touch the bodies, that's Lanie's job." she said, looking him on the face.

Coming to stand right in front of her, Castle looked her in the eye and explained "Beckett...you need to phone in the FBI. This" with an arm sweeping the room "is bigger than you and bigger than New York. You need to request Dr. Temperance Brennan. She works with a Special Agent Seely Booth. We will need her..." taking a deep breath he looked down at the ground "We will need her to make ID's and confirm my suspicions."

"What suspicions? What do you know Castle?"

"I...I've seen this before, I've dealt with this before and" shaking his head side to side "and if this is the same man...if he is here...its not good. Even in my darkest days of writing crime scenes, i could never repeat, even in words, what this man has done. So you need to call." and with that he turned away from the shocked looks that were being thrown his way and walked out into the night air.
