Derek
Rooftop

Derek sat comfortably on a roof not far from Castle's Apartment. He was in a glowing good mood. He had been eating in a quaint little sports bar not far from his 'hideout' when the glorious good news came over the TV, a confirmed kill. As an added bonus he got to see video of the blessed event. He was glad that someone was profiting from Castles' demise. That blood sucker made enough money on death, it was only right that someone was going to make money on HIS death.

Everything was going according to plan. He could wait for Martha to come home from where ever she had gone to. Perhaps she was going to pick out a casket for Castle. He hoped that Martha was feeling liberated. From all he had read, she had to drag baby Castle from acting gig to acting gig. The poor woman, Derek was sure that deep down she had to be crying tears of happiness. The dead weight was gone!. He knew that he was feeling liberated.

His mind eventually his mind drifted back to where it always did, back to Alexis. He was sure that she was hurting. He felt sorry for his daughter, that was what she was, really. He would be so proud of her, once she accepted the fact that he was her true father. Castle may have been the biological father, but he was just an immature primadonna. Derek would show her what a real father was like. A strong mature man who would take care of her like she deserved to be taken care of.

Through the scope he saw the door to Castle's apartment open. He saw the telltale red hairdo. Martha had come home.

"Hello Martha," Derek whispered as he line up the kill shot."Goodbye Martha"

Slowly exhaling he began to squeeze the trigger.........

Esposito and Ryan
The Bullpen

Javier and Kevin did not to head to their respective apartments when Beckett dismissed them, but went back to the Precinct and began going over the evidence from the shooting again. They gathered all of the interview material from the canvas to see if there was any new information. There was precious little, one man who remembered seeing the van another who remembering seeing the messenger driving around the block but nothing that would help find the bastard.

"Maybe we show try to think outside the box." Kevin Remarked

"Like how?" Esposito queried.

"I don't know, how would Beckett and Castle do it?"

"Well , Why did this guy attack Castle?"

"Cause he is a frikken loon, Esposito. He thinks he is Derek Storm."

"Exactly, this guy has to be in the system somewhere. An Asylum, Homeless shelter, a Halfway house, he has to be on some shrinks couch."

"So we need to check to see if anybody matching the shooters description has been recently released."

"Hey guys." Ryan and Esposito turned to see Agent Sorenson standing in the doorway.

"Hey Sorenson, Beckett is not her right now. What can we help you with?"

"Apparently," will mad a wry face " the Director is a fan of the writer monkey. I have3 been told to render you any assistance that you need. The FBI is at your disposal."

"Great," Esposito replied. "We have a picture of the shooter just back from the Lab. We could really use the Face Recognition software to help us get a match."

"Sure." Will supplied.

One of the CSU lab techs came running in.

"Detectives I've just finished with the digital recording and I think you are going to want to here this."

The Techie set down the laptop he was carrying and clicked the touch pad to start the recording. The sound was muffled but still understandable.

"You killed me, Castle. I could never forgive you for that, never. I'm not one of the psycho's from you books. I wanted you to die first. I did not want you to linger to see all the others I am going to kill. I hope you enjoy the experience." The voice on the recording got softer "Oh, just to let you know, not that it matters to you now, but I'll be taking out a lot of people including your beloved Nikki Heat."

"Mrs R." Esposito whispered.

"Alexis" Ryan said.

"Kate" was Will's response.

A/N: Ok, I am now officially flying blind. I wrote most of the first 9 chapters before I started publishing this. Hope this up to snuff. Enjoy!
