Castle and Beckett look into the murder of a young mathematician gunned down with a 200-year-old bullet, sparking some wild theories by Castle about a time-travelling killer. When their investigation uncovers a tricked-out DeLorean and a suspect in Victorian clothing, is it possible Castle's crazy idea has some validity? This winding tale twists through the towers of Wall Street and into the world of a secret steampunk society that embraces the romance and simplicity of the past, while coupling it with the hope and promise of the future.

Did You Know?


The first-run airing closes with a modified version of Stephen J. Cannell 's production logo (Cannell typing on his typewriter, then pulling out the page; it flutters down to a stack of papers which curl into a series of concentric C's). Here, the words "Mentor, Colleague, Friend" have been added, and the pulled page now flutters out of frame, leaving "We'll miss you, pal" on the screen. Cannell passed away earlier that month.

The Delorean has a license plate shown of LFM 26W1. When the detective calls in for a tow, he starts giving the license plate as "JLD" before he is cut off. See more »


Kate Beckett: You know, I just don't get how someone could shoot Goldstein, steal his clothes, and then not hang onto his wallet. It just doesn't make any sense.
Richard Castle: [distracted, checking his phone] Yeah.
Kate Beckett: Maybe giant moths killed him and then ate his clothes.
Richard Castle: Could be.
Kate Beckett: [bringing him back to Earth] Hey. Castle. If this case is boring for you, you don't have to stay.
Richard Castle: No, I'm just checking my e-mail, my texts, see if Alexis called. I can't believe she told my mother she's in love and is holding out on me.
Kate Beckett: Oh...
Richard Castle: I'm ...

Contains the longest dialog by Alexis
13 October 2010 | by (Malaysia) – See all my reviews

Contains arguably one of the longest sentence in these series:

"Alexis : How do you know when you're in love? I know it's an emotion, a feeling that you can't exactly define, like technically like you know you're feeling it but since I've never felt it before, how do I know what I'm feeling is even ... 'it' at all? (pause) ... Except of course for the fact that I'm feeling all these things I've never felt before, like in my stomach in my throat and even kind of in my ears. I mean which has to mean that it's love, right? Considering I only feel them when I'm with Ashley, thinking about him ... I mean it's got to be love right? (pause) Coz I'm feeling all these things I've read about in poems and heard about in songs but never completely understood but now I do! I understand it and I'm listening to all this music and reading all these poetry in a completely new and glorious light which I think just has to mean that it's love, what do you think? (pause) And I can't stop thinking about him, Daddy. I don't even want to, cause he's a greatest, sweetest, most adorable guy and those crinkles when he laughs ... and I'm just so happy. (pause) (hugs Castle ...) thanks dad ... I love you. I feel so much better now.

Castle : I'm glad we had that talk."

Much priceless was after that .... in the next scene

"Castle : Becket, how do you know when you're in love? Becket : All the songs makes sense."
