Sorry, this chapter is a little short but it's one of my favorites.

It had been about an hour from the last text and Kate was firmly planted in front of the murder board. Sure it wasn't murder, yet, but the board was still full.

Three hours had gone by since Castle and Alexis were taken. She had twenty one hours to get them back or else… no don't think like that she told herself. We will find them.

She felt bad for Nickels. He came here to help and he ended up getting terrible news. After he read the text he called his brother and told him to stay at his place with his family for just in case reasons.

She went to take another sip of her coffee and realized her cup was empty. While she was filling her cup up her mind drifted to all the good time she and Castle had shared. He had saved her life more than once. She wouldn't have thought to jump into the tub if she didn't know the bomb was already there. She would have been shot in that girl's apartment if he hadn't noticed the shooter and pulled her behind the couch. Sure she had saved him from time to time, but that was different. She had faith in herself then, now she did not. If she couldn't get to them she would never forgive herself. Castle was the joy in her life, with him gone she couldn't see herself being happy again.

By now the cup was full and the coffee went over the rim.

"Shit." She cursed grabbing some paper towel. She poured it into a different cup then went back to her desk to do some work. She needed to figure out where this guy was.

She was on her computer maybe five minutes when a message popped up.

You know what, your boyfriend talks a lot. He's trying really hard to get me to let Alexis go. He said he'll pay me everything he has in the bank. He said I could kill him in a terribly torturous way. He loves his daughter a lot. It's so touching. Anyway, that's not why I'm mailing you. I thought I would give you a very small hint.* North South East West, this will be the ultimate test. Should you give up or should you fail, that would put an end to our tale. Filled with knowledge in a Dewey way, just think about 4 down to K.*

There was no return address. This hint was confusing. It's like she knew exactly what he was talking about but couldn't put it all together. She knew that someone could though.

"Ryan, Esposito, I need your help over here." She hollered to them but then her computer screen went black. Then eight words in white letters popped up.

Sorry but the clue is just for you.

Any ideas about the clue? It took me like an hour to come up with it. Hope you like the way it going. Please LMK if you think you know what he's talking about. I'll let you know if your right. If you are you should win some cookies or something. I asked a couple friends and they were all stumped so if you can figure it out you're a genius. Please review. Thanks for reading.
