"Elementary" - "You Do It Yourself" - Dec. 6, 2012

A man stares into a masked man's face. The masked man is holding a gun. He shoots the first man.

Sherlock has a nasty cold this week and is thus also making Watson miserable. Luckily, Bell sends a text that they've got a dead body and invites Holmes to come check out the scene. They head down and the dead body is the man we saw getting shot. Turns out he was shot in both eyes. Gruesome.

Sherlock quickly deduces that this is not the crime scene and that the man is a professor of Asian studies.

They head off to the college the next day to check out his office with the help of his TA Brendan and determine that he had a thing for the number 13 and that means he was fond of gambling in Asian underground parlors.

They visit said underground parlors to find their perp. Their final destination is the crime scene-- which Holmes deduces by recently spackled walls and a janitor bleaching part of the floor. They determine the man is not the janitor but the owner-- thanks to his fancy shoes belying his janitor apron-- and discover the parlor had video surveillance. This surveillance leads them to one Raul who says he was hired to off the man by an unseen third party who contacted him only by a burner cellphone.

When they discover that Brendan had recently gotten a scathing refusal of recommendation for a job from the dead man they figure he did it. They also deduce that Brendan was having an affair with the dead man's wife- he made her awesome mix cds of sappy love songs like "My Heart Will Go On"-- on whom their suspicion now falls figuring she framed Brendan by leaving the phone in his house.

When they go to her with this theory she admits to the affair with Brendan-- who has now confessed-- but that she did not kill her husband even though she had motive-- it turns out that he was an abusive sex maniac who brought her back from Asia promising to marry her but never did and instead made her his sex slave. She wants to prove this with videos he made of his evil conquests but his computer has been wiped clean.

Holmes not believing Brendan's confession but also believing the (not)wife didn't do it is perplexed-- and now worried since the wife is about to be deported-- until Watson clues him in to an anomaly in the dead man's eyes. It turns out that the professor had a painful, terminal eye condition and only had months to live. They deduce that he discovered his wife's affair with Brendan, wrote the damaging letter to make it appear that Brendan had motive to kill him, and then paid Raul-- who lived in Brendan's neighborhood-- to kill him, asking him to shoot him in the eyes as a symbolic gesture of relieving him of his pain, and then plant the phone at Brendan's house.

This, however, is hard to prove until Watson, again, notices something. Raul lived in Brendan's neighborhood yes but a few blocks away. Why didn't the dead man find someone even closer to do the deed to help cast suspicion, like say, the registered sex offender who lived in Brendan's building. They go to said sex offender and hit the jackpot. It turns out that the dead man did approach him but the sex offender was suspicious and installed surveillance equipment and lured him back to his apartment. Armed with video showing that the dead man showed up with hit money, they are able to solve the case; as the episode title says "You do it to yourself." Brendan and the (not)wife decide to marry that day to avoid her deportation.

In the B story, Watson is called by an ex named Liam to help him out of a jam. He is in Riker's, arrested for a hit-and-run. Unfortunately, he is a former addict who started using again and blacked out the night of the accident and believes he left the keys in the ignition and someone went for a joyride. He still swears he didn't do it. Watson is skeptical. Holmes, thinking Liam is a former client, prods her gently to look at Liam's arrest report. In it she sees how badly the car was smashed and notes he didn't have a scratch on him. She also notes that a silver keychain pendant that she gave him is missing and thinks perhaps, even though it wasn't worth anything, thieves might've thought it valuable. Holmes then deduces Watson was sleeping with him and wonders how long into their relationship she waited to do this. Watson finds the pendant in a pawn shop and goes to the police. It turns out that there has been a rash of joyriders in the area and Liam is cleared. He promises Watson he will now try rehab again and asks for her help. She is understandably wary but offers to get him into a clinic but says this is all she will do, they will not reconcile, and she will not be waiting when he is done. Later, she waits at the clinic for him to show and Holmes joins her. She admits that Liam was simply an ex, not an ex client. She guesses that he isn't going to show. Holmes says he will wait with her.
