Finale time! Will my wild theories turn out absolutely right or tragically wrong? Who knows! But wrong. Definitely completely I was wrong.
Last episode ended with the dramatic revelation that the season baddie, Michael the Vaguely Creepy Serial Killer, was beaten to death. The lead suspect is Joan. The episode begins with FBI Agent Mallick interviewing Joan. She hasn’t been arrested yet, but the FBI has questions.
Joan doesn’t have a reliable alibi. That would be too easy. She was alone with her mom, who has dementia. Mallick thinks that Joan fixated on Michael. She wanted revenge on him for the way that Michael hurt Sherlock, his victims, and Joan herself. But Mallick has more than just motive to back up her suspicions.
The FBI has a tape. Michael called his friend from the last episode, Bazemore, to try and explain his actions. That puzzled me, because last episode, Michael said that Bazemore ODed. I assumed that Bazemore died and that was why Michael attacked Joan rather than continuing the cat-and-mouse game. I can’t figure out whether this was a continuity error, my misunderstanding, or somewhere in between.
Anyway. Michael called Bazemore and they have it on tape. As he’s talking, he’s interrupted mid-sentence. He says Joan’s name, and then there’s the sound of a beating. That sure sounds suspicious. Joan can’t explain it.
So back at the brownstone, she and Sherlock meet with a defense lawyer. She warns them that Mallick is a dangerous opponent. Then she literally doesn’t show up again for the rest of the episode, making the whole scene supremely unnecessary.
Alone at last, Sherlock asks Joan if she killed Michael. If she did, he’ll help her get away with it. But Joan insists she didn’t and in turn asks Sherlock if he did. Also no. Thus, they are left with finding the real killer. They can’t expect much, if any, help from the police, who will be under pressure from the FBI.
Nonetheless, Sherlock asks Gregson for the files on Michael’s murder. Gregson refuses. He says that if Joan is innocent, the evidence will prove it.
Sherlock isn’t willing to wait for that. He breaks into the morgue and steals the autopsy report on Michael. He also performs his own autopsy and takes pictures of the corpse to show to Joan.
There’s severe head wounds caused by a blunt object. That could explain why he said Joan’s name on the tape; maybe he was just confused. Also of note is that someone neatly stitched up his stab wound from Joan. Joan doesn’t think it was done in a hospital. It reminds her of emergency medicine of the kind that would have been performed in the Vietnam War. Wow, that’s a really specific thing to just know off the top of your head, but okay. It gives Sherlock an idea.
He goes to an NA meeting and sidles up to an older man named Denny. They met before at a meeting. Denny was a combat medic in the Vietnam War and he too knew Michael. When Sherlock starts asking questions, the guy gets shifty, but with some pressure he agrees to talk to Sherlock privately.
Denny hadn’t known that Michael was a killer. Michael had simply shown up on his doorstep, bleeding, with a story about an altercation with a drug dealer. Denny obligingly stitched Michael up and let him crash on the couch. He was still there in the morning, gone by the evening, and shortly later Denny heard on the news that Michael was a) dead and b) a serial killer. He was scared of getting in trouble himself so he didn’t go to the police. Sherlock promises to keep him out of trouble if he’ll just help Sherlock in return.
The dynamic duo investigates Denny’s house. It’s the last place Michael was alive…and maybe dead too. Sherlock finds traces of a lot of blood that was cleaned up in a hurry. This could be the scene of the murder. When they spray Luminol they find traces of footprints. A woman’s footprints, the same size as Joan’s shoes.
So now they know where Michael was killed. But once again, the clues point to Joan. How did the killer even know where to find Michael? Sherlock proposes a theory. Agent Mallick is the real murderer. Perhaps she was afraid that she would never catch Michael. Killing him was the only way of stopping him. Now she’s pinning it all on Joan. That would mean that our two detectives can’t go to the FBI with this new crime scene. It would only be used to further frame Joan.
That is, if the crime scene was even still there. But it isn’t. Sherlock persuaded Denny to burn his house down and gave him money in exchange. Joan is furious but Sherlock angrily stands his ground. He’ll do what he has to in order to protect her.
Meanwhile, the FBI is still chasing Joan. Mallick and some other agents interview Bell. He staunchly defends his friend, even when Mallick threatens to use the case to torpedo his chances with the Marshals.
Bell doesn’t like to be threatened. Shortly after the interview, he meets with Sherlock privately and hands over the police’s files on Michael. The two men share a tense moment of friendship and wordlessly shake hands.
Michael’s body was lying in a pile of trash. When murder victims are found in landfills or dumpsters, the trash around their body is cataloged for clues. In Michael’s case, that trash is interesting. Joan and Sherlock know the murder was in Queens. Yet, his body was among trash from Harlem. How does that happen?
Joan and Sherlock check out a facility for garbage trucks and chat with a particular sanitation worker there. When the two first began investigating Michael’s case, you may remember that they discovered a man who had been convicted of one of Michael’s murder. With Sherlock and Joan’s help, he went free. This sanitation worker, a mechanic for the trucks, is the father of that man.
Sherlock thinks that fact is important. Obviously the mechanic has no reason to be fond of Michael. Maybe Michael’s killer recruited his help in disposing of the body. The mechanic could have stolen one of the trucks, driven out to Queens, picked up the body, then dumped it. That could explain why the trash was from Harlem.
The mechanic angrily denies it. First of all, the truck facility is guarded and all the trucks are GPS tracked. There’s no way that anyone could steal one. Secondly, if someone did kill Michael, he thinks that person is a hero. He isn’t going to help anyone, even the people that saved his son, catch Michael’s killer.
As the detectives continue to explore the facility, Joan wonders if maybe it was the other way around. Rather than taking a truck to Michael, maybe the killer brought Michael to the truck. It would be easier to sneak a body in than a truck out. If so, there facility has security footage. Her face would be on camera.
But nothing’s ever that easy. When Sherlock and Joan ask the guards for the security footage, they discover someone beat them to it. A law enforcement officer came to the facility and took the tapes, leaving behind no copies. Sherlock suspiciously asks if the agent was Mallick.
But it wasn’t Mallick. The cop was a man named Gregson. Are you thinking, “ohh nooo” yet?
Captain Gregson returns to his home to find it tossed. Sherlock is waiting in the dining room. He was looking for the tape but couldn’t find a copy. Gregson must have destroyed it.
Why would he do that? For one simple reason. Hannah killed Michael. After all, he killed her roommate, her best friend. In the time since then, she became fixated on revenge. She investigated his life, learned who all his friends were, so she knew he’d go to Denny after Joan hurt him.
It was never supposed to be pinned on Joan. Hannah didn’t even know that Michael was recording when she killed him, nor did she hear him say Joan’s name. (As for why he did that, we never really get an explanation.) She disposed of his body.
Gregson never knew of any of it until afterward. But eventually she came clean to him and he realized that her one vulnerability would be the security footage at the sanitation facility. She’s his daughter. He did what he had to in order to protect her.
Now they’re at an impasse. Sherlock demands he come clean to the FBI. Gregson refuses. He insists it will all blow over and the lack of evidence will vindicate Joan. Sherlock points out that regardless, her career and reputation will suffer. Gregson blames Sherlock for Michael’s involvement in their lives in the first place.
It’s Gregson’s daughter. It’s Sherlock’s best friend. Neither is willing to budge and they part in anger.
Sherlock returns to the brownstone and updates Joan. He thinks that they should tell the FBI anyway. They don’t have proof, but if the FBI is doing their due diligence, they should at least investigate the Gregsons. That could be enough.
But Joan understands why Hannah did what she did. She doesn’t want Hannah to go to jail or for the captain to get in trouble. She agrees with Gregson; maybe it’ll just blow over. They should wait things out. It could make her adoption chances harder, maybe impossible. But she’s willing to take that risk. Sherlock still wants to protect her, but Joan says that if he’s her partner, he should support her.
At this point, Sherlock does what he always does. He takes things into his own hands and goes to meet with Hannah Gregson herself. She too never wanted Joan to be a suspect. Sherlock tells her to confess, to admit where the murder weapon is.
The FBI come for Joan. But not to arrest her. Mallick has news for her. She’s no longer a suspect. Someone else confessed to the murder of Michael and even provided the murder weapon. But it wasn’t Hannah. It was Sherlock.
Well, not Sherlock himself. He turned himself over to the British consulate, struck up some sort of deal with MI6, and they sent a messenger with Sherlock’s confession. Britain is refusing to extradite him to the US and if Sherlock ever steps foot in the US again, he’ll be arrested.
Joan returns home in shock and finds Sherlock there. He’s not supposed to be in the country anymore, but he had to see her before he left. This was the only way he could think of to extract all of them from this situation without anyone going to jail for it. Joan is angry he didn’t try harder to fight, but for him it was worth it to protect Joan. She saved his life and taught him his life was worth saving. They emotionally say good-bye and finally admit they aren’t just partners; they love each other.
For the final scene, we see Sherlock in England, in the famous 221B, consulting with a client. But he isn’t really paying attention to the man’s story of a runaway bride. His neighbor next door is distracting him with a tremendous noise. He storms next door and knocks. The door opens to reveal, of course, Joan.
They walk down the street together. They have work to do.
- I predicted that Moriarty killed Michael. Hoo boy, I was wrong! I absolutely did not see it coming that Hannah was the killer! That was a deft twist. It made sense but surprised me.
- That being said, why was there so much storyline this season about Moriarty if she wasn’t going to actually do anything?
- The scene where Sherlock and Joan said goodbye was very emotional and touching but a little silly considering that obviously they weren’t going to really part. I was sitting there tearful, but also thinking to myself, “But why doesn’t Joan just move to England too.” And she did! I was worried, though, that the line about them loving each other was going to lead into a kiss or something, especially with all that romantic crap a few episodes ago. I’m very glad it didn’t.
- It’s intriguing that the shots of them in England felt like a natural end to the show. Except…season 7 is already in the works. Hm.
- So wait, is this the last we’re going to see of the rest of the American cast? No more Bell? We know he’s going to the Marshals, so he’ll be okay, but no goodbye scene? That’s sad. Farewell, Bell. I’ll miss you!
- This is our season finale, so see you all next season!
