Full Episode Recap
Early in the morning, police officers mounted on horseback gallop through Central Park and come across the body of a young man, clad only in boxer shorts. He looks to have been shot.
At the loft of Richard Castle, he is meticulously making an omelet of graham crackers, marshmallows and chocolate for his mother, Martha Rodgers, and daughter, Alexis. He dubs it a “smorlet” and offers one to Martha, who politely declines. He then offers his creation to a seemingly distracted Alexis, who graciously accepts, then casually asks if her friend Ashley can come over that evening. Castle agrees. Alexis puts a forkful of omelet in her mouth, and is disgusted. She spits it out in her napkin and asks her father if he used marshmallows in his recipe, having not paid attention to its preparation. When he answers affirmatively and adds that he also used chocolate, Alexis quickly proclaims that she has to go, gathers her things, and leaves. Castle observes that she seemed “a little out of it” and Martha tells him that she confided in her the night before that she is in love. Castle disputes his mother’s assessment, saying that if she was in love, she would have told him. Martha again disagrees, saying that the fact that she hasn’t told him, proves that she really is in love. He presses her for details and Martha says she knows nothing, not even the guy’s name. Castle then pouts that Alexis doesn’t consider him her “go to guy” anymore and Martha tries to reassure him that it’s Alexis’ first love and therefore, it defies logic. His cell phone rings and he ignores it, still pouting. Martha finally picks it up and cheerily tells him that it’s Beckett calling, undoubtedly about a murder, which should perk up his day. After grinning slightly, he answers.
As Castle and Detective Kate Beckett walk through Central Park, each holding their usual coffee, to find the corpse, Castle laments his situation to Beckett, saying that he has always been there for Alexis: when she took her first steps, when she learned how to ride a bike, and when she said her first word, which was “denouement.” Beckett tells him not to worry, that she’s seen how Alexis looks at him. She then quickly warns him that girls like Alexis who are close to their Dads, typically grow up to marry guys just like their fathers, a fact which bothers Castle.
They finally find Medical Examiner Lanie Parish kneeling over the body, and she chastises both Castle and Beckett for never bringing her coffee. Castle offers her the rest of his, and Lanie declines, saying she doesn’t drink coffee, but would appreciate a bear claw pastry every now and then. Beckett turns the subject back to the dead man, and Lanie tells her that the cause of death is a single gunshot wound to the chest, possibly from a .45 or a large caliber gun and that her estimated time of death is around midnight. Castle then recognizes the victim’s boxers as a very comfortable, expensive silk brand of which he owns a few pairs. When Beckett asks if Lanie has any idea about why the victim was out in a park with no clothes on at midnight, Lanie stops Castle from spinning a wild theory, answering that she found fibers in the wound, indicating that he was clothed when he was shot, then stripped. Beckett speculates that the killer was worried about forensic evidence being on the clothes and removed them to protect him. Detectives Javier Esposito and Kevin Ryan arrive with the victim’s wallet: he is Daniel Goldstein, 25 years old from Soho, and an employee of a Wall Street investment firm. Castle is confused about what he was doing in the park if he both lived and worked further downtown. Beckett hands the wallet to Esposito and Ryan, telling them to get it to the lab and stands to leave. As she walks away, Castle asks her what type of underwear she wears, saying that it’s only fair since he told her what he wears. Only Beckett gives up nothing, merely smiling coyly and continuing her walk out of the area. Castle ticks off several different types of women’s underwear, until his mind goes wild when the possibility that Beckett goes “commando” occurs to him. Lanie finally shuts him up with a look.
Back at the precinct, Beckett and Castle interview Goldstein’s sister, who is shocked that her brother was found unclothed in a park at night since he barely even drank and had no enemies. It’s not like him, she insists. She goes on to explain that their parents were killed in a car accident when they were twelve, making him a very cautious person. He had no girlfriends or even much of social life, was a workaholic and a bit of a nerd. He got a PhD in mathematics from MIT and instead of taking a position as a professor as she had hoped, he took a job at the investment firm, working on special fund products when they offered him a substantial salary. Ryan indicates to Castle & Beckett that he’s found something and when they step outside, he tells him that the lab got a hit on a fingerprint on Goldstein’s wallet. When Castle asks who, Ryan merely gestures to the interrogation room, at a loss for words.
A little bit later, Beckett sits in the interrogation room confidently interviewing a very large, intimidating, strong man wearing all black and sporting several tattoos on his arms. Castle stands firmly behind the table, obviously scared. Beckett rattles off the man’s record: 3 violent assaults in the last month, one where he inflicted several broken bones and bit the nose off his victim, among other injuries. She then suggests that murder was only a logical progression, but wonders why he stole Goldstein’s clothes. The man, named Roland D’Andre, flatly denies killing Goldstein. Beckett then asks him why his fingerprints were found on Goldstein’s wallet and why Ryan and Esposito found a .45 caliber gun in his possession, which matches the type of gun that was used in the shooting. When he says nothing, merely glaring at Castle and making him even more nervous, Beckett asks why he resisted arrest, throwing Esposito through a wall in the process, if he was so innocent. In the observation booth, Ryan tries to reassure his partner that with the right turtleneck or scarf, nobody will notice the thick neck brace he is wearing. Esposito turns stiffly to glare at his partner, who gives him a brotherly punch on the shoulder, causing Esposito to grunt in pain. Back in the interrogation room, Beckett demands that D’Andre confess. He claims that Goldstein was already dead when he found him, which Beckett disputes. Castle gingerly suggests that he come up with a better story if he is innocent, and D’Andre jumps angrily out of his seat, causing Castle to recoil back against the observation room window. He tries to play off his reaction as nothing, but Beckett sees through it.
Castle and Beckett step out of the interrogation room and are met by Ryan and an angry Esposito, who demands that Beckett fry the guy. Beckett promises she will, just as soon as Lanie confirms that the bullet that killed Goldstein came from a .45.
Down in the morgue, Lanie tells Castle and Beckett that the bullet isn’t from a .45 at all, but is a bullet she’s never seen before. Beckett looks at it under a microscope and notices that it is a round ball and made of lead. Lanie says that judging by the amount of oxidation, which turned the ball white, she estimates that it is 200 years old. Castle then supposes that they have a time-traveling killer on the loose. He tries to get a high-five from Lanie, but she has exasperatedly walked off, with Beckett not far behind.
Back at the precinct, Castle is still spinning his time-travelling killer theory to Beckett as the two exit the elevator and walk to the murder board. When Castle suggests that they need a time machine, Beckett says that the age of the bullet doesn’t necessarily rule out D’Andre. Ryan arrives and begins debating Castle’s theory, saying that if the killer had traveled through time, the bullet would have been brand new instead of showing a thick coat of rust. Castle shoots back that it’s possible that time travel caused the rust on the bullet, leading Beckett to muse that it could also cause Castle’s brain to rust. She then asks Ryan if he asked Goldstein’s sister about the antique bullet. He reports that she had no idea where it came from, but that an antique weapon expert Beckett requested has arrived and should be of assistance.
Castle & Beckett speak to the expert, who concludes that D’Andre’s gun did not fire the lead ball, since it hasn’t been modified to do so. Castle whispers to the Beckett that it’s possible D’Andre was telling the truth, and Beckett agrees, saying that whoever stole Goldstein’s clothes could have dropped the wallet next to the body when stripping him. Beckett asks the expert what kind of gun could have fired the ball, to which he responds a wide variety of 18th century flintlocks. He says that if Beckett can bring him the gun, it can be matched to the ball, but that the type of gun needed is not readily for sale, but rather a collector’s item that doesn’t need to be registered.
Outside, Beckett tells Esposito that D’Andre isn’t their murderer and Captain Roy Montgomery assures him that the man will do serious time. Montgomery offers to let Esposito take a couple days off to recover and suggests that he see a movie. Castle suggests that he read Naked Heat, getting an embarrassed smirk from Beckett. Esposito refuses both, insisting that he is fine. Montgomery gently pats him on the shoulder and heads back to his office. As Beckett and the guys return to the murder board, Ryan tells Beckett that the victim’s clothes still haven’t been found and Beckett wonders aloud what is so special about the clothes that made the killer take them. Castle supposes that the killer traveled through time naked and needed the clothes, a suggestion Beckett laments that she doesn’t have the evidence to refute. Castle and Ryan do a quick “feed the birds” sign behind her back, while Beckett thinks aloud about what a Wall Street math expert like Goldstein had gotten himself into. Castle then pulls out his phone, as Beckett asks Ryan and Esposito look for antique gun clubs or social media websites that Goldstein might have had contact with, while she and Castle visit his workplace. She heads for the elevator and Castle, still studying his phone, follows her, oblivious to everything she is saying. When they arrive at the elevator, in an effort to get Castle’s attention, Beckett suggests that a giant moth killed Goldstein then ate his clothes. Castle is still lost in his thoughts, so Beckett suggests that he go home if the case is boring him. He says he is not bored, but just checking his emails and text messages for word from Alexis about her new love, about which he is still upset that she told Martha and not him. When he says he wants to call her about it, Beckett snatches the phone from him and tells him to give her time, because her Dad acted similarly with her when she was Alexis’ age and she ended up dating a smelly grunge rocker for seven months. Castle relents and they climb aboard the elevator, Beckett denying to Castle that she ever mentioned a giant moth.
At Goldstein’s office, Beckett and Castle interview his boss, Adam Murphy, who is just as confused as his sister, since Goldstein wasn’t much of an outdoors type, nor did he have an interest in guns. He confirms that Goldstein liked to work late, saying that he left work the night before at around 9:30p.m. Goldstein’s assistant, Julia Foster, enters, seemingly shaken, bringing a tea service. She says that nothing terribly out of the ordinary went on the day Goldstein died, just that some unhappy investors had called. Murphy goes on to explain that one of the funds Goldstein had created three months prior to his death tanked, causing investors to lose millions of dollars and leading to some very nasty phone calls. Beckett asks for copies of the phone messages and a list of clients who lost money in the fund.
Back at the precinct, Esposito is looking through the list of unhappy clients while Ryan searches the internet for antique gun clubs and enthusiasts Goldstein might have been in contact with. Montgomery asks about their progress and Ryan says they aren’t getting far: of the sites he’s found, none of the gun collectors match up with any of the clients who lost money in the failed fund. Montgomery joins Ryan and admires some of the guns displayed on an antique gun website. He invites Esposito to look too, and the detective stiffly swivels in his chair and comments on the artistry of the guns made in the 1800s. He says that the investors in Goldstein’s failed fund each lost at least $1 million. Montgomery comments that if he had that kind of money, he wouldn’t invest it, but rather keep it hidden in his mattress. Ryan pulls up the profile of another antique gun owner, Ivan “Yosemite Sam” Podofsky, who Esposito connects as one of Goldstein’s investors. He lost over $4 million in the failed fund and left a message for Goldstein threatening to put him in front of a firing squad.
In an interrogation room, Castle & Beckett have pictures of Podofsky’s gun collection on the table, and Beckett plays Podofsky’s message for him. He pleads that he was just upset at having lost $4 million. Beckett asks him for an alibi for between 11p.m. and 1a.m. and he says that he was asleep at home and has people who can vouch for him. Podofsky also describes how Goldstein took an interest in his gun collection when they met several months ago and asked him if he knew where he could get a Sherlock Holmes gun. He then suggests that Goldstein’s interest was what got him killed. Beckett asks him if he would be willing to submit his guns to being test fired to see if they match the lead ball that killed Goldstein. When Podofsky balks, Beckett asks if he’d rather be arrested for murder and he agrees.
At the murder board, Beckett posts Podofsky’s picture as a possible suspect. Ryan reports that ballistics has taken possession of his guns and should have preliminary results the next day. Esposito enters and says that he got a hit on a traffic ticket issued on Podofsky’s car from last night. He hands over a copy of the ticket to Castle, who is happily shocked when he sees that Podofsky drives a Delorean. He insists that the make of the car, being the same as the one used in the Back to the Future movies, proves his time-traveling killer theory. Beckett notices that the ticket was written at 2a.m., after Goldstein was killed at a location nearby the crime scene. Esposito says that the car should still be in the same place. Castle asks why, if Podofsky is going to park illegally, didn’t he park closer to the crime scene. Esposito answers that Podosfky has been issued multiple parking tickets in that same area, indicating that he parked in that area to go somewhere other than the park, like to a girlfriend’s. Beckett teases Castle about whether or not a time ripple is in the area, giving Podofsky the ability to jump through time and Castle muses on the possibility. Beckett gives him a doubtful look and tells Esposito to pick up the car.
Ryan and Esposito locate Podofsky’s Delorean and cannot help but like it. Esposito locates the flux capacitor and Ryan the reactor core. Esposito gets on his phone to request that the car be towed as Ryan looks around for why Podofsky might be coming to the area regularly. He sees an eccentric looking man dressed like he belongs in Victorian England, complete with a bloodstained shirt, and pushing a shopping cart laden with bags. Ryan gets Esposito’s attention and the two approach the man, who introduces himself as Lord Henry. When Ryan asks where he got his clothes, he answers that they came from a haberdashery across the park. He then bids them both good day and tries to leave. Esposito stops him and begins saying that they think the clothes belong to a murder victim, when Lord Henry gets agitated and drives his shopping cart into Esposito, making his neck injury worse. Lord Henry pulls a sword from the cart and goes for Ryan, who is eventually able to subdue and cuff him.
Back in the morgue, Beckett tells Castle that Esposito went home to rest and that Ryan confirmed Lord Henry’s story, finding a matching ascot in the garbage can where he says he found Goldstein’s clothes. Beckett asks why Goldstein could have been wearing a Victorian costume and Castle says that it fits with his time-travel theory. Lanie enters saying she is just as confused as they are, having found gunshot residue on one of the gloves and coat sleeves, leading Castle & Beckett to conclude that Goldstein was armed and fired back at his assailant before he was killed. They head back to the park with Ryan, where an officer with a metal detector locates another lead ball like the one that killed Goldstein. Castle then has a thought and connects the facts that Goldstein was wearing turn of the century clothes, fired a lead ball identical to the one fired by the killer and that bells from a nearby church would have allowed Goldstein and the killer to know that it was midnight. He walks off forty paces between where Ryan found the second ball and where Goldstein’s body laid and announces that Goldstein and the killer must have been engaged in a duel.
Later that night, Castle walks to the front door of his loft and decides to surprise Alexis and her friend. As quietly as possible he unlocks his front door, pulls one of Podofsky’s antique guns out of its case and goes charging through his front door. To his great surprise, he finds Alexis making out on the couch with a young man, who jumps up immediately, terrified at the sight of Castle with a gun. Alexis admonishes her Dad and tries to fix her slightly disheveled hair, while telling Ashley that her Dad will not shoot him. Castle makes the connection between the young man and the friend named Ashley who Alexis wanted to invite over that morning. Alexis introduces the guys and takes her Dad aside, demanding that he explain himself. Castle says that the gun is for research on his latest murder case and admonishes Alexis for not checking in with him. He then demands that Alexis explain herself. She defends her actions by saying that her kissing a boy shouldn’t pose a problem and that she only invited him over so Castle could meet him. Ashley then says that he should be going and Alexis invites him to stay. Castle then apologizes for the gun and also, albeit sternly, offers to let Ashley stay. Ashley insists upon leaving and asks if he can call Alexis later. He then nervously tells Castle how much he respects Alexis. Castle thanks him and shows him out, watching him closely the whole way. Once gone, Castle says he likes Ashley. Alexis slaps him on the shoulder and angrily stalks off.
The next morning at the precinct, Castle arrives as Beckett gets off the phone with ballistics, which has cleared all of Podofsky’s guns. She also says that Goldstein’s sister and co-workers have no idea why he was dueling, wearing Victorian clothes or frequenting the area where Podofsky’s car was found. Castle follows her to the break room, where she hands him a cup of coffee from the espresso machine. Castle suggests that Goldstein was dueling because a woman was involved and someone insulted his honor. He then tells Beckett about how he almost shot Alexis’s boyfriend the night before. Ryan comes in and, responding to Castle’s question, says that Esposito is staying home since he can barely move. He also explains that he found a pile of receipts in Goldstein’s car and on the back of one was written a notation about an appointment with a Troy Kenworth, whose father lost everything investing in Goldstein’s failed fund and eventually committed suicide. Afterward, Kenworth was charged with assault in 4 separate bar fights. Castle suggests that Kenworth murdered Goldstein out of revenge and Beckett guesses that the duel was an effort by Kenworth to settle their score.
Later, Beckett interviews Kenworth alone in the interrogation room, wanting to come off as the motherly type, while Castle and Captain Montgomery observe from the observation room. Kenworth tells Beckett how he found his father’s body and began drinking after his father died. When Beckett gently presses him about how she can understand his blaming Goldstein, Kenworth says he did initially, then he says that Goldstein told him he had been pushing his father to diversify his investments and that his mother left his father because of growing financial problems. The loss of his marriage pushed him over the edge, not the fund collapsing. Even so, Kenworth says that he had to quit school and that his mother could barely afford the rent on their apartment. He goes on to say that he met with Goldstein some time ago and that the meeting turned him around: he quit drinking, he and his mother have been able to make their rent payments and he might return to school in the fall, all because Goldstein got him a job. When Beckett asks where he has been working, Kenworth says he can’t say, until Beckett threatens to arrest him.
When Beckett and Castle arrive at the address given them by Kenworth, they find, after Beckett forces their way past the doorman, that it houses a steam punk club, where members dress as if they are in 1892 London. Castle is enthralled, seeing actual recreations of machines he has read about in some of his favorite books. He explains to Beckett that stem punk society celebrates the simplicity of the past as well as the promise and hope of a future made better through innovation. They meet up with the club President, who tells them that Goldstein left the club around 11:30 on the day he died and that he knew nothing about anyone in the club dueling. He shows Beckett and Castle a set of dueling pistols, which Beckett examines, observing that both have been fired recently. Castle notices that the lead balls match the type of ball that killed Goldstein. They then notice Goldstein’s boss, Adam Murphy in the club dressed in stem punk attire. Murphy immediately takes off running through the club and Beckett and Castle give chase. Meanwhile, outside the front door, Ryan tells a still sore Esposito that he doesn’t have to come in to work and Esposito continues to insist that he is OK. Ryan flashes his badge to gain them admittance. The front door opens and Murphy runs out at top speed, colliding head on with Esposito. Beckett and Castle reach the doorway and spot Esposito and Murphy lying in a heap on the ground. Castle nonchalantly asks him how his neck is and he only groans in response.
Back at the precinct in interrogation, a distraught Adam Murphy confesses to shooting Goldstein and to stripping him of his clothes. He adds that Julia, Goldstein’s assistant was there, since he and Goldstein were dueling to impress her and that her panicking when Goldstein went down caused him to panic as well. He explains that Goldstein was in love with her, she wasn’t interested in him, and that Goldstein had caught him and Julia fooling around in his office, so they decided to duel in hopes of impressing her enough so she would go out with one of them. Murphy also pleads that Goldstein assured him that neither of them could get hurt, having run a number of equations that mathematically proved that an antique dueling pistol like the ones they used could not possibly fire a ball accurately enough to hit someone at forty paces. Julia confirms his story and Beckett tells Ryan to let her go.
Outside at the murder board, Castle guesses that the two got so caught up in the romance of dueling that it never occurred to the two guys that someone could get hurt. Beckett supposes that after the failed fund and the duel, Goldstein wasn’t as much of a math genius as people thought. She further says that she needs to recommend to the D.A. whether or not Murphy should be prosecuted for murder or manslaughter – the difference being life in prison or a few years. Her decision hinges upon whether or not antique pistols really are as inaccurate as Goldstein thought they were. Castle tells her that there is only one way to find out.
Not long afterward, Castle and Beckett test the pistols at the precinct firing range. Their first shots miss, Castle’s going so awry that it hits the target meant for the booth next to his, angering the uniformed cop practicing there. After Castle’s second and third shots also miss, the officer begins helping Castle, giving him various apparatus that are meant to ensure an accurate shot. Beckett needs no such help, but still all of her aimed shots miss wildly as well. None of the aimed shots hit anywhere close to their targets, convincing Beckett to charge Murphy with manslaughter.
Later that evening, Castle is in his office at his loft trying on his own steam punk costume when Alexis walks in. The two hug and both apologize to each other for the night before. Alexis says she has an embarrassing question for her Dad and he promises to do his best not to embarrass her even more with his answer. Alexis asks him how do you know when you are in love, but before he can answer she babbles on at length, going from being unsure about whether or not she’s in love to listing all the feelings she is feeling and how happy Ashley makes her. The whole time, Castle tries to answer, but can’t get more than one word in at all. Finally, Alexis concludes that she is in love, hugs Castle and thanks him for the talk. She leaves and Castle’s front door buzzer sounds. He opens the door to find Beckett standing in the hall and asks her Alexis’ question. She answers matter-of-factly that you know you are in love when all the songs make sense and enters his apartment, not the least bit surprised by Castle’s outfit. She tells Castle that she doesn’t believe that Murphy killed Goldstein, and that he only confessed because he thinks he did. She explains that she ran ballistics on the dueling pistols and found that the bullet that hit Goldstein didn’t come from either. Castle concludes that there must have been a third shooter present and Beckett agrees.
Back at the park, Ryan climbs a tree and finds that Murphy’s shot did go wild of where Goldstein must have been standing, killing a squirrel instead of Goldstein. Beckett then surveys the scene and guesses that if the real killer had wanted to shoot Goldstein without either him or Murphy knowing, he would have fired from a nearby clump of trees. A CSU tech finds some red clothing fibers in one of the trees, which Beckett instantly recognizes as coming from a stem punk costume. Castle then realizes that he not only knows who the killer is, but what weapon was used. They head back to the stem punk club and find Troy Kenworth. They tell him that they found his father’s shotgun which he had modified to fire antique lead bullets, that they proved that Murphy couldn’t have shot and killed Goldstein, and that they figured out that he fired the shotgun at the same time that Murphy fired his pistol, making Murphy think that his shot killed Goldstein. Kenworth then admits that he killed Goldstein because he couldn’t stand to see him in the club every night spending money freely while his father lost everything before killing himself.
Back at the precinct, Castle & Beckett tell Captain Montgomery that Kenworth overheard Goldstein and Murphy planning the duel and took it as his opportunity to exact revenge. His alibi, having worked at the club all that night, fell apart when they interviewed other club staffers who say that he wasn’t anywhere to be seen around the time of the duel. Captain Montgomery then asks if Castle & Beckett heard about Esposito. When they both look confused, he points behind them, where Ryan is wheeling Esposito, clad from the waist up in braces, in a wheelchair. They approach him, shocked, and then suddenly he jumps out of the chair, pulling the braces over his head. Ryan laughs heartily, slaps Esposito five, and thanks Captain Montgomery for his help in selling the prank. Castle goes to slap Esposito on the shoulder, only to have the detective wince. Ryan quickly puts his neck brace on, and Esposito says that he still isn’t completely healed.
Then a voice calls Beckett’s name and everyone turns to see a tall, handsome man casually dressed in jeans and a leather jacket. Beckett asks him what he is doing there, calling him Josh, and he tells her that even though she texted him that she would pick him up, he was in the area and decided to come by anyway. Beckett introduces him to the guys and then goes to get her things from her desk. Josh turns to watch her and when he turns back, finds himself toe-to-toe with Castle. Castle tries to mine Josh for information about his relationship with Beckett, only he doesn’t give much up. Josh eventually recognizes Castle as “the writer,” but when Castle asks who he is, Josh merely observes that Beckett obviously hasn’t told him about the two of them. Castle tries once more to discern the nature of their relationship, but is interrupted when Beckett arrives at Josh’s side. Castle is even more surprised to find a motorcycle helmet and goggles under Beckett’s arm. Josh bids Castle good bye and he and Beckett leave, arms around each other. The guys, all intrigued, watch them go.
Back home at his loft, Castle opens his front door and peers around it, eventually cracking one eye open. He asks Alexis if she is alone and when she responds positively, he opens both eyes, enters as normal and sits down next to her on the couch. She thanks her Dad again for the talk of the night before and observes that being in love is exhausting. Castle agrees and quickly loses himself in his thoughts. Alexis regains his attention and announces that she wants to go on a date tonight. When Castle gives his consent and tells her to have a good time, she says that she wants her date to be with him and that he will always be her go-to guy. Castle then asks her if Martha put her up to the date, and she feigns ignorance. Castle sees through her act, accepts the pity date and gives his daughter a big hug.
