Castle and Beckett have headed from the engineering office and directly to the hotel room of the woman's whose phone was tracked to the victim's penthouse room.

When they arrive at the suite and knock they are met with silence

"I wonder if she has left the hotel and is running?" Kate remarks"

"We can ask at the desk and see if she checked out yet" Rick continues

Kate looks at Rick "Let's check first with the excursion list and see if she was scheduled to do something…"

"And if she showed up this morning" Rick finishes

The pair head back to the registration desk and approach the assistant "Did Yvette Chapman schedule for any excursion today?"

She looks over the list "Yes. Her and her husband were on the list to play golf"

"Do you know if she showed up to play?"

"Oh yes. I checked her in personally"

Kate looks at Rick "I wonder if she is still on the course?"

Once more the assistant speaks up "Oh she is still out there! Last time I talked to anyone, she is 5 strokes below the next player and is on the mark to win the grand prize"

Kate's face falls slightly then speaking softly to Rick "I don't think she would still be here if she was our killer"

"She would have already left" Rick remarks

"We know she was with our victim last night though"

"Or we believe she was. At least her phone was"

The assistant speaks once more "Oh, I saw her leave the ballroom just after Charles Ivy last night"

"What time was that?" Beckett asks

"Oh about 11:30 or so"

"That matches our time line" looking back to the woman "did you see her husband leave too?"

"It was even later. I mean a lot later. He was pretty drunk though when he did"

Kate looks back to Rick "OK we know she was with Ivy" Then Kate then looks back to the assistant "Did you see anyone else leave the ballroom after they did?"

"Only her husband. He was looking for her and got pretty agitated. I think one of the hotel staff had to escort him back to his room"

"So, he was that drunk?"

"Oh yeah"

Rick looks at Kate "I wonder if her were too drunk to have attacked Ivy?"

"Sounds like it" Kate looks at the assistant "Thank you and let us know if you think about anything else" Kate responds as her and Rick turn to leave

Castle and Beckett are waiting in the meeting room the hotel has allowed them to use for the investigation. A uniformed officer has been sent to wait for the suspect and bring her to the pair when she returns from the golf course

Just looking at the notes they have made Kate's mind drifts back to the many…many times she has arrested a jilted lover or unknowing spouse for killing a paramour in an attempt to try to save the marriage or relationship

Rick can feel his wife's mind is rushing through the current case and he feels her thinking in his own heart and he moves to be closer to her "I am trying to understand how we get here so many times?"

A smile shows on her face "Yeah…I guess some couples can become disconnected, but I cannot understand how two people who love, or at least once were in love, go down to this level"

"Remember when we talked to the call girls about their clients?" Castle comments "She said it was not always about the sex. Most of the clients were missing the emotional connections not just the sex"

Kate steps up next to her husband and leans into his chest "I guess we are the exception? I have never felt like we lack emotional or an intimate connection" she looks in his face "And I hope I have filled all your needs?"

"No question…" He kisses her hair "Always"

If it weren't for the investigation and the need to question the suspect within just a few minutes these two might have made a hasty retreat to the privacy of their room. But knowing they must strike while the iron is hot they pull apart and are waiting at the table when the uniformed officer arrives with Yvette in tow

Pointing at the chair across from the duo Kate begins with her strong cop mode "Yvette, we need to ask what happened last night?"

"What do you mean HAPPENED? Nothing happened. Why?"

"Kate pulls out the print out that Gus had given her earlier "We know you were with Charles Ivy in his room last night"

"What do you mean? With"

"I think you know what we mean" The interrogator in Beckett responds "You were in his room for over an hour. What happened? I mean besides sleeping with him?"

"Nothing happened"

"How long have you been sleeping with him?"

The woman realizes she is caught but she is going to make one last ditch effort to deny "I did not sleep with him last night"

Castle decides to chime in as he and his wife have done so many times "Then why is there a toothbrush found in his bathroom with female DNA…"

Beckett finishes "We are getting a warrant right now to compel you to provide a sample and I think it will prove it was yours"

Knowing she has no chance of getting out of the situation, she finally confesses "Yes. OK! I slept with him. He was good looking, rich, it was fun…and my husband has spent most of his time lately sleeping with groupies at concerts and no time with me. My husband was so drunk he did not even know I had left with Charles"

Kates looks once again at the page in front of her then showing the woman her husband's cell phone number showing up on the printout "Then why did he go to the room later?"

She ducks her head "He came to get me"

Kate lets the badass side of herself come out "And to kill Ivy for sleeping with his wife?"

"NO! NO! He did not kill Charles"

"You killed him then?"

Yvette's face goes red "No, Kate, he was very much alive when Ronnie and I left"

About this time there is a knock on the door to the meeting room and the local uniformed officer enters "The victim's partner need to see you. She said it is urgent"

"Listen, I need you to stay in the hotel until we get this sorted out"

"OK" Yvette responds as she stands and walks back out

Kate looks at the officer "Send Ms Hopkins in"

The uniformed officer leave the room and returns just a moment later escorting Nancy Hopkins

"What is it Ms. Hopkins that is so important that it couldn't wait?"

"I just got a call from our accountant. The company bank accounts are almost empty. We are close to bouncing checks all over the place. A lot of money is missing"

"How much money?" Rick asks

"Over twenty million dollars. All the reserves are gone and the operating accounts are very low. The money is just…Gone"

"Does the accountant know what happened to the cash?"

"She said it appears that Charles has been spending the money over the last few months"

"Spending it where?" Kate asks

"From what she can tell he has been using it to pay gambling debts"

"Did he have a problem with gambling?"

"Yes. In the past, he would bet on the horses, go to Atlantic City, or even fly to Vegas, but he had been working on the problem. I had encouraged him to go to Gamblers' Anonymous and I thought he was getting better"

Rick looks at Kate "I wonder if he paid off some of the bookies then this hotel and ran out of cash

"Maybe he still owed another bookie somewhere…" Kate chimes in

"And they sent in an enforcer…"

"But they wouldn't come to kill him, just to encourage payment…"

"That explains no outside weapon…"

"Ivy tried to defend himself with the lamp…"

"A fight ensued…"

"And the collection efforts turned into a murder?"

"We need to check the printout for another cell phone in the area"

Kate takes the paper "Here is a number that does not match the contact number of any of the attendees"

"That must be the one"

There is another knock on the door and a group of men enter without introduction "We are looking for Captain Beckett "

"That's me" Beckett responds

"I am Ron Blackwell and we are here to take over the investigation"

Sometimes the Feds just get in the way
