| − | |text=Holmes has a different theory: Barrett is working on her own solution to P vs. NP, and killed Soto and Nauer after seeing how close they were to beating her to it. He notes that she used to own a dog of the same breed as the hairs he found, and used to own a gun of the same model that shot the two men. Angry, Barrett says the dog died weeks ago, the gun was stolen from her, and she has an alibi for the night of the murders: she was having dinner with a friend, Wayne Kaneshiro, at a pub. A security video from the pub confirms that she was there at the time of the murders. She is innocent, and Holmes and Watson are no closer to finding the murderer. |

Plot
| "A correct proof would essentially render all modern encryption obsolete." — Linus Roe
|
| Mugger Benny Charles holds up a man and then hits him with his pistol. Fleeing, Charles walks through an alley and hears a gun shot and witnesses a man being shot in a home. The murderer comes out of the house and shoot Charles. The next day, Watson visits the grave of Gerald Castoro, the man she accidentally killed during an operation. His son Joey arrives and presses her to have coffee with him. Having heard about Charles' shooting on his police scanner, Holmes shows up at the crime scene even though Detective Bell texted that he wasn't needed. They view the body of Felix Soto, a math tutor, on his living room floor. Bell indicates that Charles is in a coma in hospital. They both notice that one of Soto's rooms is completely empty. Holmes smells the walls and asks a confused Bell to find a black light. Holmes finds a stand-up lamp with one and once the blinds are drawn, he turns the light on to reveal math equations written on the walls.
|
 |
| At a diner, Joey congratulates Joan on being a detective and she learns that he's dropped out of university, despite his father wanting him to become an engineer. He asks if she'd invest in a bar he's bought and applies some guilt tactics on Watson. She asks how much he needs. Returning to The Brownstone, Watson is surprised to find a shirtless man examining a projection of the math from Soto's house. Finding Holmes in the kitchen, he explains the man is Harland Emple, a math professor, who is determining if Soto's equations were worth killing over. Watson asks Holmes for an advance of $5000 to help the son of a friend but they are interrupted by Emple. He explains that Soto was trying to solve P vs. NP, a math problem with numerous applications and has a $1M prize for solving it. Emple indicates that Soto was close to solving the problem. From the handwriting, Watson deduces that Soto had a male partner and Emple indicates that another P vs NP expert, Tanya Barrett, may know who the partner is.
|
 |
| A college professor, Holmes and Watson question Barrett in her office. She knew Soto but quit working on P vs NP years before. Watson mentions Soto's partner but Barrett indicates Soto was a loner. To provide possible partners, she offers math journals but Holmes finds a proof in one journal matching the partner's handwriting. Barrett identifies the author as Cyril Nauer. Holmes calls Bell to report the lead but Bell says that they've found another dead body, Cyril Nauer. At the Morgue, Holmes recounts that Nauer was killed an hour after Soto and, by the same killer. Watson notes that CSU found dog hair on Nauer which Holmes identifies as Boston Terrier. Watson reminds Holmes about the salary advance and he's deduced that it is for Joey. Watson describes the circumstances leading to Gerald's death and how much she appreciated that Joey didn't blame her. She confesses he's asked her for money before but they are interrupted by a call from Bell summoning them to Nauer's apartment.
|
 |
| On the street outside Nauer's, Bell reports that they found a bug in his apartment. Holmes deduces that he was being watched as well and sees a camera on a post aimed at Nauer's window. Hailing a cab and jumping on its roof, Holmes finds a signal jumper on the back of the camera which can be traced back to the receiver. The receiver belongs to Roe Encryption whose president, Linus Roe, is questioned in his office by Bell, Holmes and Watson. Roe denies knowing Nauer until he finds out he is dead. Roe tried to fund Nauer's work but when he wouldn't take any money, he turned to surveilling him. He explains that an application that could crack any computer security system could be built from the solve of P vs NP. With the application, Roe's company could built a counter-solution. He says they were also watching Soto. However, Roe brought Soto and Nauer's work to Tanya Barrett to evaluate who told him that they weren't close to a solution, contrary to Emple's evaluation.
|
 |
| In "the box" at the 11th Precinct Barrett says that although Soto and Nauer had made great progress on P vs NP, they were only a third done and it would be years before they solved it. She lied to Roe hoping he would back off pursuing a solution as she knew what he was doing was wrong. Captain Gregson confirms she owns a Boston terrier Holmes points out she owns a pistol the same as the murder weapon. She says the pistol was stolen and denies killing Soto and Nauer to use their work. She provides an alibi during the murders, she was having dinner at a restaurant with a man, Wayne Kaneshiro. The restaurant sends security video with a timestamp that confirms Barrett's alibi.

|
| Watson comes downstairs to see Holmes doing sit-ups in the living room, facing a wall of photos, other mathematicians devoted to solving P vs. NP, and thus potential suspects. When Joan asks why he won't go jogging by the river, and yet do calisthenics at 3:00 am. He explains that cardiovascular exercise stimulates blood flow to the brain, "and the river smells like rotten cod." Standing, he confides that, against his better judgment, he has agreed to Watson's request for an advance, and points to a shoebox on the counter. Looking through it, Watson is confused to see at least $20,000.00, when she only asked for five. Holmes says her best course of action is to give it all to Joey, and thus ensure that it will be years, or never, before he hits her up for money again. Protesting, Watson insists that Joey isn't taking advantage of her and she genuinely wants to help him, but that sounds feeble even to her. Holmes tells her that he is an expert on deadly poisons - yet he has learned that guilt is much more toxic than any substance known to man.
|
|
| Holmes approaches Professor Barrett at TriBoro College again. At first she brushes him off, but he says he has a different theory. If she can't have been the killer, then the fact that all the available clues pointed to her indicates that she is being framed. Holmes asks if anyone she knows might have a grudge against her. Looking disbelieving, she says the only person she could think of would be her ex-boyfriend, Jason Harrison, who seemed to take their break-up unusually hard. The police interview Jason Harrison, confronting him with a series of threatening emails, sent to Barrett from his address. Harrison swears he has never seen those messages before, and has no idea what they're talking about. Gregson and Bell seem to believe that Harrison will crack eventually, but Holmes is not so sure. Then they get a call from the hospital: Benny Charles has regained consciousness.
From his hospital bed, Charles says that his assailant was a woman in glasses, not a man. Joan shows him Barrett's photo on her smartphone, and Charles says he is positive it is her.
|
|
| At the precinct, Holmes and Watson are watching the security video from the pub over and over again. Barrett's alibi seems unshakeable, yet all the clues point to her, and Benny Charles swears that she is the person who shot him. Since they are arguing in circles, Joan diverts the conversation back to Joey and Holmes's continuing refusal to endorse her decision to loan him the money. Holmes says she might as well keep the money for herself, and do something useful for it, like buy 5,500 beers. After a moment, Joan asks him how he came up with that figure, and Holmes motions to the security video, showing a heavyset man laying a $10 bill on the bar in exchange for four glasses of beer. Joan remarks that beer in a Manhattan pub usually isn't that cheap, except during happy hour. Sherlock says that is impossible, the video's time stamp shows that it was taken much later in the evening, at the time of the murders... the digital time stamp. And just like that, the case is solved.
|
|
| Holmes, Watson, Gregson, and Bell confront Barrett in her classroom. Holmes admits that he was wrong: Barrett wasn't trying to solve P vs. NP before Soto and Nauer - she solved it weeks ago, but needed to keep the fact that a solution existed a secret, until her programmer accomplice completed the computer code to implement it. If the solution was revealed too soon - for instance, by Soto and Nauer - then the world's banks might change their cryptography systems before Barrett had a chance to stroll in and steal billions of dollars. The proof: Wayne Kaneshiro, the friend with whom she was dining, has already confessed to being her accomplice programmer, and that he tampered with the security video to make it seem as if it was taken much later in the evening. At the time in question, Barrett was not actually in the pub at all - she was killing Soto and Nauer. Kaneshiro also used the code to write and send the phony emails from Jason Harrison's address, to strengthen her alibi.
|
|
| Joan meets with Joey, and tells him that she has decided to help him, but instead of giving him money, is helping him in a more roundabout way, because she is concerned that he is becoming too dependent on her. When she returns home, she is surprised to see Holmes boxing up the case file, including the photos of Soto and Nauer's equations. He confides that Barrett has been taken into custody by the federal government, who have also confiscated all the maths related to P vs. NP. Deciding that the solution is a threat to national security, the government is keeping it a secret until countermeasures can be developed. Instead of being indicted for murder, Barrett will be held in protective custody while she assists the government with those countermeasures. Watson reflects that Linus Roe was wrong, and the world will go on much as it has before, now that P vs. NP has been solved.
|
|
| Holmes congratulates her for her elegant solution to the Joey problem. Watson cannot dismiss some lingering doubt whether Holmes was reluctant to loan her the money because he was worried she would not pay him back. Holmes dismisses her doubts, saying that money is about as useful to him as a collection of Hummel figurines. He then surprises Watson by asking if he can accompany her to her next visit to the Castoro grave site. The man, either through his life or through his death, obviously had a profound impact on Watson, and was indirectly responsible for her becoming Holme's's partner. Holmes feels he owes the man his respects. Pleased, Watson says she would be glad for Holmes to come along next time.

Music
- Eric Doherty - Lightning Rod plays as Watson meets Joey Castoro at the Court Square Diner.
Trivia
- The episode was produced as the third episode of the season, but was aired as the second episode.[1]
- Watson and Joey Castoro have coffee at the Court Square Diner located in Long Island City.
- The solution to this case is similar to that of Dorothy L. Sayers's classic mystery novel Have His Carcase, in which all the evidence points to the killer having committed the murder, except his alibi seems unshakable. Once the detectives alter the time of the victim's death, the case is solved.
Quotes
But I've come to learn over the last few years that there is nothing on this planet quite so toxic as guilt.
— Holmes to Watson
