I'm doing my damndest to get this all up by the time season 4 shows. As such you are probably going to get a chapter a day, or at least as fast as I can edit them. I've still got the last chapter to write, but I'm hoping it will come fairly easily.

Chapter 23: He's not the Devil

It had taken Beckett half an hour to come up with a valid enough excuse to duck into the tech room and away from Chloe who was checking churches.

Beckett had waved at Castle who had followed her in curiously. "Beckett? What's wrong?"

Beckett focused on him, there was only so long they could stay in here and they did have a murderer to catch, but she wanted Castle's opinion on Lucifer and Chloe. "What do you think of Lucifer?"

Castle frowned. "He's very…confident." Beckett gave him an irritated look, Castle was being careful, dancing around the edges of what Beckett wanted him to say. She needed Castle to be his usual ridiculous self, she needed an outrageous theory so she could shut down the niggling voice in her head.

"There's just something about him that doesn't seem right." Beckett told him and Castle relaxed ever so slightly. "He's really attractive though." Beckett threw that in just because she knew it would irritate Castle.

It worked because Castle rolled his eyes. "If you like that sort of thing I suppose."

Beckett forced them back on topic. "He works for the LAPD so he must have gone through all the same checks as you, but he still seems…I don't know like he has a few screws loose. He really seems to think he's the devil."

Castle nodded. "Yeah, but not the usual version." Castle flicked a look at the door and lowered his voice conspiratorially; despite herself Beckett leant towards him. "Maybe he really is the devil."

Beckett straightened and levelled a very flat look at Castle and rolled her eyes. "Seriously Castle. He's not the devil. The devil doesn't exist. It's just a persona he uses." It was good to get that off her chest, said aloud the idea was ludicrous.

"What about that weird hypnotism thing and he reads the language of the angels!" Castle insisted.

Beckett considered walking out the room because now that Castle had veered off into a ridiculous theory her edginess about Lucifer did feel very silly. She stayed put a minute longer. "What about Chloe?"

Castle smiled. "I like her, she reminds me of you."

Beckett sent him an affectionate smile and shook her head at him. "She's a good detective, but she's definitely hiding something."

"Oh yeah, no question." Castle agreed and Beckett felt better. It always made her a little more sure footed to know that Castle agreed with her. She was a confident person by nature, but if Castle with his lateral writers mind agreed with her then she could be sure what she was feeling was definitely accurate.

"Whatever Lucifer's deal is, she knows all about it." Beckett told Castle. She pulled aside the blinds into the little room. Lucifer and Chloe were standing by Beckett's desk; Chloe was writing something down and looking very focused. Lucifer was watching Chloe with a sharp attentiveness he didn't seem to show anything else. "Not our biggest problem at the moment." Castle told her.

Beckett nodded and moved towards the door. "I think Chloe has the church."

Beckett was right, Chloe had sifted through the churches that matched the name Lucifer's translation had given them and had an address. They only had a few hours to get everything ready for their killer.

I'm a little worried Beckett and Castle went a bit OOC in this chapter. I just couldn't quite get them to work the way they should. I'd finished rereading the Lucifer comics and re-started up with Daredevil which really shouldn't affect Beckett and Castle at all, but I think it really has. I even watched a few of my favourite Castle episodes, but try as I might I couldn't get it working. So slightly off chapter, sorry.
