The “Elementary” episode “Poison Pen” was teased as involving someone from Sherlock’s (Jonny Lee Miller) past, but it’s much more than that. We also learn a few juicy details about Sherlock’s psyche, and what made him who he is today.
Titus (Steve Greenstein), a man wearing a latex body suit, is found dead by a dominatrix (Keesha Sharp) who had been called in to show him a good time. Sherlock is actually friends with her, although she is not the woman from Sherlock’s distant past. She’s just somebody he bonded with over a fascinating discussion of historical torture devices.
It turns out the man has been poisoned by nitroglycerin. In the search for the man’s killer, Det. Bell (Jon Michael Hil) stands at the front of the local sex toy shop and shows his badge to everyone who walks in until the owner finally gives him the name of the man who purchased the body suit: Titus’s boss, Jeffries (Paul Fitzgerald).
But Jeffries has an alibi during the time of death. He simply dressed Titus’s already dead body in the body suit so his business wouldn’t have to pay Titus’s family $125 million in benefits because of a morals clause.
In search of the killer
Sherlock and Watson (Lucy Liu) next take a look at the family, but Sherlock quickly knows who the next suspect should be: the nanny. He supposedly recognizes her from news broadcasts long ago, when she killed her father with nitroglycerin. She has since changed her appearance, and her name to Anne Barker (Laura Benanti) from Abigail Spencer.
Sherlock quickly realizes that Abigail is innocent, but nobody believes him. Plus, Watson believes that Sherlock’s recognition goes deeper. It turns out that he used to correspond with her when he was 15 years old.
Sherlock found that he could finally talk to someone about the severe beatings he would get in school, because she was also being abused… by her father. Sherlock confesses to Watson that he knew she had murdered her father, and communicating with Abigail allowed him to see into and understand the mind of a killer. It’s what helped him become a fantastic investigator. The only problem is that he truly believes she’s innocent this time.
Putting away a killer
Sherlock makes himself known to Abigail, also informing her that he knew all along that she had killed her father, but that he doesn’t believe she killed Titus. She’s immediately offended, and kicks him out.
Meanwhile, the gang researches the possibility that Titus’s wife (Noelle Beck) or children killed him. Coincidentally, the wife could not have done it because she was too busy planning to kill Titus in the exact way that he was murdered. Then there’s the son, Graham, who stands to inherit millions when he turns 18 in a year.
Then the clincher: Titus had accused Abigail of stealing his tablet computer. When they find the tablet hidden in a vent, they find out why he didn’t want anyone to see it: he kept videos of himself sexually abusing Graham. Graham is the killer.
Abigail refuses to allow Graham to go through what she had gone through, being victimized by the press. She confesses to the crime, feeling that she will finally get what she deserves for killing her father.
Sherlock refuses to allow Graham to get away with murder so easily, for his own good. Sherlock tells Graham that he knows the truth and will come after him if he ever does it again. But he also offers to be there for him if he ever needs someone to talk to. After all, Sherlock too, understands what it’s like to be a victim.
“Elementary” airs Thursdays at 10 p.m. on CBS.
