The captain and her husband are moving a little slowly as they exit the elevator at the 54th and move across the floor toward Detectives Sexton and Byron

"Hey you two…how was lunch?" Sexton asks while looking at these two with suspicion

"Uh…it was very…" Castle starts to answer the Beckett finishes "Satisfying"

She looks around the room "Did you pick up Bailey?" she asks trying to move the conversation off their lunch break back to the case

"He's in interrogation room 2" Sexton responds as he points toward the end of the hall

Beckett drops her bag on the desk she is currently using and looks in the direction of the room "Castle and I will go in there. Again, if you two watch and let us know of any questions you want asked"

Sexton and Bailey both know there will probably not be any questions for them to add. It is very evident that his woman knows all the questions needed to be asked before she even meets a suspect.

Beckett and Castle enter the room and the door closes behind them

The man looks at the two entering and knows that they are not there to remark on the fine dinner they had the other evening at the president's home

"Professor Bailey. Do you know why you are here?"

"I am sure you are looking for information about the death of Dr. Sellers"

As she drops her pad down Beckett responds "That is correct" she opens her notebook and looks at the first page "You knew our victim well, correct?"

"Yes. I have known her ever since she came to the school. I am tenured at the university and have seen a couple of presidents over the years"

"Are you aware of her escapades with men including other facility members?" Beckett questions

The man looks down to the table "Yes" looking back up "Everyone knows. Her indiscretions and conquests are well known among the male staff…and to the distaste of the females as well"

"So are you one of her trophies?"

"No"

"Are you sure?" Castle remarks "She was a beautiful woman. Easy to get to know" Rick suddenly feels his wife's eyes burning into his neck, then he tries to finish his statement "it would have been easy to fall victim to her spell"

"I am sure" the man replies while sweat seems to begin on his forehead "But I did not"

Kate moves her stare off her husband and back to the suspect, then comments "So you were not tempted by her charms?" she then looks back in Castle's direction once more as if asking him as well

"No. Absolutely not! I love my wife and would never cheat on her"

Castle remarks "Me either" He then looks at Kate who seems to have put an evil smile on her face

She then shifts back to her badass mode "So where have you been going several times a week, if not to see the woman?"

"Uh…how did you hear about that?"

"We have information that you have been coming to the school early and staying late several days each week and it looks very suspicious"

The man looks down at the desk top and pauses several heartbeats before answering "I am been tutoring. Teaching extra classes…to earn some extra money"

"Tutoring?" Beckett questions. That was not what she expected as an answer

"Yes. I teach a few extra classes each week to earn money for something special"

"What something special are you working toward?" Castle asks

"Promise you won't tell my wife!"

"Mr. Bailey, it all depends on what it is. If this is something we need to verify, she will probably find out"

He glances around the room as if looking for an escape "Our 25th anniversary is coming up and she has always had her heart set on a trip to Hawaii and I couldn't afford the nice trip she wants, so I have been working extra teaching jobs to earn the money so we can go. I am almost there. You can check with the travel agent"

Shifting gears once more Beckett changes her questioning "Do you know of anyone in the staff or facility of the school that still owns an old style typewriter?"

That question definitely caught Bailey off guard. He thinks for a minute then answers, but he definitely does not want to give a response "There is an old typewriter at my wife's church. In fact it sits on the credenza immediately behind her desk…why?"

"That is not the one we are looking for. Do you know of another one?"

This time he seems to think very hard "The only other one I am aware of is at the school library. It is in the display case of old office equipment the school once used. In fact that is a very, very old one. I think from over seventy-five years ago, around the war. In fact the curator thinks it had something to do with World War 2"

"OK Professor Bailey. We will be verifying your story about the trip to Hawaii and if it is true, we will make sure your wife does not find out, but you do know she thinks you were having an affair with Dr. Sellers…and that is why you come to the school so early and left late"

"I know, but I was planning on telling her next week because I have almost all the money I need to pay off the trip"

Castle looks at the man and feels that his story is true "I am sure she will forgive you when she finds out what you have really been up to, but don't wait too long to tell her"

"I won't" he responds as Beckett stands and tells him that he can leave

Back in the squad room Beckett and Castle have rejoined the two detectives "Well that is a surprise" Sexton remarks. "I was sure he was fooling around"

Bailey adds "It had all the ear marks of an affair"

"Yes it did" Rick comments "I just goes to prove that men can be faithful to their wives even when they look guilty" He looks at Kate who has not even acknowledged his remark, but he believes he can see a tiny upturn of her lips

"OK guys, let's contact Ryan and Esposito. They were going to interview Blaire Collins father to see if he can shed any light on this case"

Beckett calls the 12th on the video conference unit. When the phone answers they see the face of Kevin Ryan

"Hey Ryan…has anyone looked at the typewriter at the school?"

"Just got the report back from forensics. It is not the unit used to type the note, but they say it seems to be the same model, just not the exact one"

"So it is still probably one that came from the school. Have you looked to see if there are anymore out there?"

"Yeah. I talked to the asset clerk. She remembers them disposing of a large number of them back about 20 years ago when they started using computers almost exclusively. She said she doesn't remember where most of them went, but the last one was the one at the history display in the library"

"Well keep digging. Did you get anything helpful from Blaire's father?"

"As a meter of fact, yes" Ryan looks at his notes "Blair Collins had admitted to her dad that she was having an affair with Bailey and she knew he was also seeing Sellers, but he told Blair he was only doing it to protect his job and she believed him"

"Women will believe about anything their men tell them" Beckett remarks "But obviously he was just dragging her along"

"Yes. And her father tried to tell her to stop and she wouldn't and he told her that he would stop her support and he would see to it that the other, behind the scenes, activities would be halted"

"How was he going to stop the other?" Castle asks

"It seems the Blair Collins' father is on the board of regents of the university and they had already been looking into the little Peyton Place they had going on there and working on a solution to the activities"

"What kind of solution?"

"He said that the Board of Regents were meeting in closed session about that and the lawyers told them to not disclose what they had been planning"

Castle looks at Beckett "I wonder if the solution included the removal of the president"

Bryan finishes the thought "With extreme prejudice?"

"I am sure the board never discussed murder" Sexton responds,

Castle gets a funny look on his face

"What is it Castle?" Kate asks

"What if the board didn't do it but one of the board members?"

"Good question" She responds "He would have to have a typewriter to send the note"

"And I know who would likely have one"

Beckett gets a knowing look on her face that she realizes she knows also "Then let's go talk to him"

She looks at the two detectives then hand them a note "Get a search warrant for this person's home…specifically looking for and old typewriter of the same that the school used and we will be back in the morning"

Castle and Beckett step into the elevator. Castle is worried about a conversation he knows he needs to have with his wife "Kate…listen"

She turns toward Castle and takes a hold of his face with both hands "NO you listen…" a smile crawls up her face "I just love having more ammunition to torture you with"

"Oh,just torture? Huh? No punishment?"

She puts on her most sultry look and gets right to his lips "Naked Punishment"
