This was only going to be a two shot But I got so many asking for me to continue it.
I am trying to figure out where it will go, buit just like Marlow once said, the charachters tell you where to go, So I am letting them tell me where to go

12th Precinct

Both Detectives Ryan and Esposito keep looking at the elevator waiting for it to announce the arrival of the captain. They had a long and serious conversation about what they should or should not do when she arrives

Detective Javier Esposito wants to walk into Captain Beckett's office and announce to her that her, in no uncertain terms, that her old man is stepping out on her.

Detective Kevin Ryan has a different opinion. He thinks they need to talk to Castle and get him to work things out with his estranged wife before it goes so far they can never get it fixed

"Listen Kevin…" the fire in the Latin detectives eyes is sharp and strong "She does not deserve to be cheated on by that two timing gigolo. Once a playboy, always a playboy. It's in his blood. He is going to cheat on Kate and by doing so he does not deserve to have her and she definitely does not deserve that kind of treatment"

"Javi! What are you saying? This is all Castle's fault? From what I heard, from good sources, she moved out leaving him standing in their loft no knowing what is going on. Does that sound like he did this?"

"No, but I just know his history. She met him during an investigation where he was signing women's boobs and picking up women for late night flings"

Kevin continues his defense "Don't you think if he had ready done something she would tell Lanie? And she has not mentioned a reason for the split"

Esposito look toward the boss's office. "In fact Lanie says Kate won't talk about it with her"

"So that means Beckett did something…maybe did something really bad to ruin the marriage"

Javier Esposito grits his teeth "Are you saying SHE stepped out on Castle first? She…and what this tech guy from DC are? You know…" he takes a breath "No man that is not what is going on but we need to figure it out"

The elevator bell rings and when the door open the pair see the tall writer steps pout. He has a cat eating canary grin from one ear to the other. He is carrying only one coffee cup and is whistling

When he arrives at the desk that was formerly Kate's he sits down "Good morning detectives"

With a death glare in his face Esposito's eyes are cutting the space between himself and the writer "Really? Bro!"

"What?" Castle responds innocently

"Lose the 'I just got laid' voice"

"What do you mean?"

"First! I am a trained detective…and second you told us where you were going last night and it is not cool to be doing this here and especially not now. Not at all!"

"Javi. I have not done anything wrong"

"You mean going down to 7th Avenue was NOT doing something wrong. That place is full of hookers

"Esposito. I promise the last person I was in bed with was my wife"

"In bed! Right! So where did you do it last night? Do it in the car?"

The voice of Captain Beckett comes in loud and strong "Do what in the car?"

"Nothing" both men respond at the same moment

"OK" she responds "Castle what are you doing here?"

"I…uh…I just come by to see if you had a case I could help on"

She looks at him with her famous glare "No! We do not have a case and even if we did, you need to stay away. You have no reason to be here anymore" she turns and walks to her office and closes the door

Castle just stands outside the captain's closed office door then finally turns and moves back beside the desk of detective Esposito. The same desk that he had sat beside for many years before

Esposito finally speaks up to Castle "That is exactly how we all fell now Castle" he points his thumb in the direction of Beckett's office "I think it is best you leave right now"

"Gus. I told you that I have done nothing wrong here. I am the one who has been wronged here"

Ryan walks up beside Javier's desk and looks at Rick "Castle. I think it might be best if you leave right now"

"OK I understand" he stands "but you need to know that I have done nothing…"

Javi speaks up firmly "Listen. We heard you the first time, but her asking for a break does not give you the right to be stepping out on Beckett"

Ryan finishes the thought "and I think you need to leave the precinct and don't come back"

Castle stands and starts walking toward the elevator with the same dejected look he had in the past when Kate was dating Josh Davidson or Tom Deming

The elevator doors open and he steps in, moves to the back wall and drops his head against the rear of the cab

Once out on the street he hails a cab and gives the driver the address for the Old Haunt. Once the car pulls away from the curb there is a vibration coming from his pocket. He pulls out a burner phone and opens the screen to read the message

'That was hard to watch'

He types a response 'Even harder to experience'

'I wish we didn't make the guys think you would cheat on me'

'I know. On my way to Cavern'

'Let me know when you have something'

'K'

"luvU'

'U2'

He puts the phone back into his pocket then looks out the window watching the city scape go by

In fifteen minutes he arrives at the bar. Once inside he goes down to the office and closes the stairway door locking it to provide total privacy. He moves across the office and pulls open the bookcase passage and moves into the underground corridor toward the East River.

What no one is aware of, Richard Castle also purchased another building a block away and reopened the secret underground bootleg pathway in between. When he arrives at the new office he goes up to the street level where a legitimate travel agency operates.

The travel agency is a perfect cover for this covert activity. His office manager and lead investigative agent, Jake Garrett, as the head of the travel agency and is an expert in counter terrorism.

Castle found him through his contact with Agent Gray from so many years before. Agent Gray was happy to set Castle up with a former operative. At least with Gray, Rick felt like he had a person he could trust to open the necessary doors. With the attacks that occurred against he and his wife they both knew there was a leak in either the department or one of the other agencies and it was going to be difficult is not impossible to locate someone they could trust

Jake is a former member of the FBI, then Homeland Security. After a short stint in the CIA then NSA he moved back to the private sector. He was never comfortable working on activities that might endanger US citizens and he refused to become involved in the type of actions that LockStat and Bracken represented and now with his knowledge, Castle feels like this might be their only chance to find the ghost.

When Castle enters his secret office inside the travel agency she sends a message to Jake that he is in the building. A few minutes later there is a knock behind the bookcase and Castle presses a release button to open the pathway.

The tall yet handsome man enters the office "Rick, What do you have for me?"

Castle holds up the flash drive Kate gave him before leaving his side earlier this morning

""Backstory information Kate gave me. I looked at it but it does not make any sense"

Garrett takes the USB and looks at the device "It might be encoded. I will look at it and let you know" The man walks to the opening then turns back "Any luck in figuring out who the mole is in the department?"

Castle shakes his head no

"Are you two being careful?"

Yeah. In fact we did something last night that made Ryan and Esposito think I am cheating on Kate. They blew up at me this morning when I came in the precinct"

"Is that were you were coming from this morning when you dropped her off?"

"Yeah. We spent the night in a no tell motel"

"Listen, I know this is hard for you two. Why don't I set up a getaway for ya'll. I can do a scan and make sure you have a couple of days alone without thinking about this case

"Jake that would be nice. I appreciate that and I know Kate will too. Thanks
