|Directed by||Bill Roe|
When a guilt-ridden young woman confesses to the murder of a struggling actor -- knowing details only the killer could know -- Beckett and Castle seem to have an open-and-shut case, until they uncover proof that their suspect couldn’t possibly be the killer. When a second person confesses, equally convinced they committed the murder, the team realizes the case is far more mysterious than they thought.

- Castle: Do I smell coffee?
- Beckett: If you do, it was made by elves.
- Castle: You should know you’re engaged to a genius.
- Beckett: Yes, a genius at annoying me.
- Beckett: If I have to hear that confession one more time, I'm gonna shoot someone.
- Castle: Alexis. What's going on?
- Alexis: Dad can I come home?
- Castle: Come here.
- It was confirmed in this episode that Alexis broke up with Pi.
- Interestingly, Pam's goal for killing Justin, which was to cause a scandal that would cause EHI to be shut down in revenge for her brother's death, would come true, as Beckett revealed that EHI was shut down pending an FBI investigation.
- When being interviewed, the "suspects" all state that there was a painting over the fridge in the room, but in the tape of the original "murder", there was no painting there.
