* AssholeVictim: A mugger who just punched out a man stumbles onto a murder while running away, and gets shot twice in the chest for his trouble. He doesn't die, and him waking up from a coma is why the killer is identified.

Joan is at the grave site of the patient who died on her, meeting with his son Joey Castoro. They go for coffee and Joey asks her for money. He intends to open up a bar and needs funding. Back at the Brownstone, Sherlock has hired a mathematician to see if he recognizes the formula. It turns out to be the famous P versus NP, a mathematical formula that has been pursued for years. While the formula is not complete, the discovered research is the closest anyone has gotten to solving it. The mathematician points out that the writing was done by two people, and also suggests he visit Tanya Barrett, a professor who wrote a paper about P versus NP. Watson asks Sherlock for a raise to give Joey the money, but Sherlock thinks that Joey is guilt tripping her into doing so.

Joan is at the grave site of the patient who died on her, meeting with his son Joey Castoro. They go for Coffee and Joey asks her for money. He intends to open up a bar and needs. Back at the Brownstone, Sherlock was hired a mathematician to see if he recognizes the formula. It turns out to be the famous P versus NP, a mathematical formula that has been pursued for years. While the formula is not complete, it is the closest anyone has gotten to finding it. The mathematician points out that the writing was done by two people, and also suggests he visit Tanya Barrett, a professor who wrote a paper about P versus NP. Watson asks Sherlock for a raise to give Joey the money, but Sherlock thinks that he is guilt tripping her into doing so.

Sherlock and Watson visit Tanya at the university she teaches at who points out a potential suspect, the second mathematician. She claims the two had been arguing and recently had a large fallout. Sherlock calls Bell to tell him about the suspect, but before he has a chance to say so, Bell informs him about another victim, naturally the same man. Sherlock and Watson visits the mans apartment, and Sherlock notices something strange about the security cameras outside. He hails a cab, stands on the roof, and notices a device on the camera pointing into the door. Sherlock goes to the man responsible for the surveillance Linus Roe works at the Security Firm the camera was made by. When questioned, Roe states the P versus NP was going to bring a huge change in security. With it any password could be hacked. Sherlock replies to Roe, that he must have wanted to get ahead and prepare for this new era.

The police bring in Tanya for questioning, and claim the bullets and dog hairs from the crime scenes match the gun and dog she owns. Tanya agrees, but points out that the gun was reported stolen and she has an alibi, going out for drinks with a friend. She the gun was stolen by her ex-boyfriend Jason Harrison, who had been harassing her with emails. The restaurant sends them the footage of the times she claims she was present, and her alibi appears to be true. They bring in Harrison, who denies involvement, claiming to not even know the victims. Gregson points out that he sent threatening emails to Tanya and claimed he complained the she cared more about the mathematicians then him.

Just as Harrison seems to be the culprit, the mugger wakes up and is questioned. He identifies his shooter as Tanya Barrett. Sherlock and Watson look over the footage again and Watson remarks how cheap beer is. Sherlock realizes the video was shoot during happy hour, which is not the time the stamp claims it was shot at. Sherlock and the police confront Tanya, tell her that she used the P versus NP code to hack the time-stamps and send the emails, and Sherlock informs her that her partner confessed. Sherlock and Watson go back to the Brownstone and he agrees to give her twenty-thousand dollars, but only if Joey agrees to go back to College like his father wanted him to.

Watson offers the money to Joey, but only if Joey agrees to go back to College college like his father wanted him to.

A man is being confronted by a mugger. He insists that he does want any trouble, only for the mugger to punch him out. The mugger slips into a driveway to count his money, when he hears gunshots from the house. The mugger repeats what the victim told him, only to be shot twice.

Sherlock arrives at the case, and explains to Bell that he got a text message from him. When Bell denies such a thing occurring, Sherlock checks his messages again and finds out it was someone else. Already at the scene, Bell allows him to have a look. The first victim was a mathematician. Sherlock and Bell search the house for clues, when Sherlock notices there is an empty room. Sherlock darkens the room, and shines a black light, revealing math formulas written on the walls.

He returns to the Brownstone, where he hires a mathematician to see if he recognizes the formula. It turns out to be the famous P versues NP, a mathmatical fomula that has been pursued for years. While the formula is not complete, it s the closest anyone has gotten to finding it. The mathematician points out that the writing was done by two people, and also suggests he visit Tanza, a professor who wrote a paper about P versus NP.
