This fanfiction is just before Caskett confronts Rebecca Strong from the episode Overkill. There was someting about it, I thought they should have consider.

Enjoy.

Beckett finished her call to Wilder's company and gestured to Castle to get in the car. She sat herself behind the wheel and started the car. Finally we got a break on this case.

"I just got the head of the employment department of Wilder's company on the phone. He told us that Rebecca Strong showed up for work today and he assured us that she will still be there, when we gets there. He offered to call her to his office for us, but I told him that we shouldn't raise any red flags, since Rebecca is going to be there anyway."

"Great," was Castle's comment as he pulled the seatbelt. He began singing: "We are off to see the blackmailer."

"Zip it," hissed Beckett.

"As you wish." But he was still in great mood, because Demming wasn't tagging along with them. It gave him some satisfied feeling, that he was Beckett's partner, not Demming.

But wait, he wasn't really Beckett's partner. He was just a bestseller novelist, who used his connections to get to shadow her.

And the murder was Beckett's case, not Demming's. So maybe it wasn't that much of a big deal, that Demming didn't come along.

Speaking of the case, a thought came to Castle. A thought that began nagging him.

Beckett noticed his expression. "Something wrong?"

"No," he quickly said. "And yet…"

"What?"

"It's just that…, if I was blackmailing someone and I thought that they didn't pay me, then why not go through with my threat?"

Beckett frown. "What do you mean?"

Castle began explaining. "We know that Wilder was blackmailed by Rebecca aka 'Scarlett O'Hara'. But the number one rule in blackmail is to have knowledge, solid knowledge, on your victim, that he doesn't want to see the light of day. And Rebecca must have some dirt on Wilder – and evidence on it, whatever it was."

"Mhm," said Beckett. She was following him so far.

Castle continued: "And rule number two in blackmail is to make your victim understand that he has to pay, if he doesn't want you to make your knowledge public. You have to make him understand that you are serious. Why kill him for not paying, when you could just go through with the threat?"

"You're right, that doesn't make sense, that Rebecca should kill him for not paying, if she had something damaging on him," agreed Beckett.

Silence filled the car again as their grey cells worked through that problem.

"Maybe…," began Beckett.

"Maybe what?"

Beckett looked at him for one moment. "Maybe she got rid of the evidence."

Castle frowned confused. "Why would she do that?"

"Maybe Rebecca told Wilder, that she would give him time to get the money and leave it at the motel. Later she contacts him again…"

"To ask if he has follow the instructions," continued Castle. Now he was getting what Beckett had in mind. "He says he has, and asks her to destroy or turn over the evidence she has against him, so they are even. She does and goes to the motel to pick up the money…"

"But Benny has already been there, found the money and rans off to Atlantic City with it. And when Rebecca doesn't find the bag under the bed, she assumes that Wilder has deceived her," concluded Beckett and turned the car around a corner.

"Which leaves her with no money – and evidence. But with a great humiliation. Now, that would be motive to kill Wilder." Castle leans sideward in his seat to look through the window. "Are we there yet?"
