Thanks to everyone who has been reading and reviewing. I've been looking for a Castle/Lucifer story for a while and eventually decided that I'd have to write my own. So I'm glad there is a little niche of people out there who are enjoying this. Another short one for you, sorry about that. There are going to be longer scenes once I get everyone together.

Chapter 4: It's called Enochian

The next morning dawned and found Beckett back at the murder board. She had a restless night's sleep, only partially helped by the large coffee Castle had brought in this morning for her. They were all back to throwing around theories about the killer. They had settled on a working theory of cult or religious extremist. The word serial killer was hovering around without being said, they only had one body, but they were all getting the vibe.

"Detective Beckett!" Captain Gates hurried up to the four of them gathered around the murder board. "I have that translation for you." Gates passed her a sheet of printed paper with a few lines of text.

A surge of excitement went through Beckett, finally a decent lead. She read through it quickly, Castle leaning over her shoulder. "Who is the consultant that can read...the language of the angels?" She asked. The apparent language fitted with either of their theories and the words were appropriately religious. Unfortunately it didn't really give them the lead they were looking for.

Gates shook her head. "I don't know, but be grateful." She said firmly glancing at the board. "Do you have anything?" She asked.

"Nothing sir. This is going to be our best lead I think." She waved the paper slightly. "There can't be that many people who can read and write in this…language. We'll start there."

"Keep me appraised detectives." Gates told them as she returned to her office.

The three men looked at her. "So what's the plan?" Javier asked.

Beckett considered for a moment. "You and Ryan see if you can work out where someone would go to learn this language." She handed them the email. "Castle and I will go back to the church and see if Father James knows anything about it."

"Right." The other two detectives returned to their desks.

Castle bounced on his toes, he was as eager as she was to get a new lead to follow. "Do you think the priest knows something?"

Beckett shook her head as she followed him towards the elevator. "Not specifically, but I'm hoping someone in the congregation has been asking about this language. Castle had his phone out. "Enochian." He said.

Beckett looked at Castle in surprise. He turned the phone screen towards her. "The language of the angel's is called Enochian."

Beckett nodded. This case was getting weirder by the second.
