I doubt it's someone in the police force.

  1. The premise of FL's talks is always about something that is not very obvious. Something that 99% of profilers, detectives, and the best minds, dismiss. Something "outside".
  2. Police force is too obvious. I seriously think it is a misdirection. "Misdirection" is always employed to mislead the best investigators, and is usually one of the most forgotten training.
  3. The writer needs a twist.  If audiences figure it out by E06, interest will immediately wane.
  4. Writers, especially for mysteries and crimes, never create characters for no reason at all. Every character has a role to play in the entire mystery.
  5. Reminds me of Sherlock Holmes and his archenemy Moriarty.

In other words, the serial killer is someone very close to her. Someone she sees regularly. Someone she won't have second thoughts or suspicions. A person who knows her almost intimately because she bared herself at least once. An entity who thinks like her and sees her as a game, a challenge on who's better.

Considering all that, there are only two people that fits the bill: the two psychos, I mean, psychs.

  • A. Female psych. She's the closest to her. They even have drinks together. She practically knows the FL intimately. And all these times, she was helping the FL how to solve her cases. As if she's nudging her without actually leading her. And the psych is always exactly right.
    • The FL doesn't even suspect her. Why would she? They've been talking together for 10 years.
    • But you see, if the female psych is the FL's Moriarty, then she's enjoying pretending to be her psychologist. She's enjoying playing with her. And she's enjoying seeing how far her archenemy can go.
  • B. Male pysch. The FL used to have him as her psychologist. He knows her deeply. He understands her.
    • He is also suspicious because he's the only regular character that we rarely see an interaction. What's more, he became the psych of the policewoman. I'm suspecting that the policewoman will be used later to commit a crime or to pin the FL as the serial killer.
    • In addition, he's also in the position where he can be close to her, thus, the FL won't suspect him at all.
  • C. The real common denominator with all the puzzles, all the victims more likely visited one or both of the psychologists before. Either one of them is the real suspect, or both psychs are in it together.

At the end of the day, it is a war between geniuses. Again, genius and psychopathy are simply two sides of the same coin. The killer, or killers, is/are interested in the FL. They probably want to train her to be like them or they see her as their antithesis.

You see, there is this belief that we all have an antithesis. An individual that is in total opposition to what we believe in and our principles. Not necessarily evil or opposite. Think of positive and negative forces. Or your battery. Or the two poles. West and East. North and South.

For the Moriarty type, it's a game. All they care about is themselves and their antithesis. Meanwhile, for the Sherlock type, it's a case they must stop and they think it is their job to solve it no matter what.

But one thing uniter them both. They both hate to be outwitted. The FL is already showing cracks when she can't understand why the father would rather commit suicide instead of taking the three guys with him.

Imagine if the female psych was the FL's Moriarty and she sees the FL cracking? Immense satisfaction and disappointment. But the psych nudge her to a certain direction because she's not done with her and it would be a waste if she's defeated already, they barely started the game!

Great deduction!🏆 

My theory is that it's the lanky policeman.

Yeah, I see that angle. 🤔🤔

In the comments section, the poster was pointed out how 4 of those in the puzzle pieces are already dead.

This implies that they left clues in the poster.

The question is, how much of it is half-truths, misdirection, or if it's everything.

Still on the poster. If they left clues there, could that also mean the ML and FL are the suspects?

  1. ML. He could be the Moriarty-type to the FL. From the get-go, he suspected the FL. Could it be that it was part of his plan? Could it be that he wants to observe her if she remembers anything and use her to get a clean serial murders? Or, like Moriarty, he sees her as a challenge and someone to play with? To prove that he's better than everyone?
  2. FL. Maybe it isn't a Sherlock-Moriarty type at all. Maybe it's a Hyde and Jekyll type. The FL has another personality. Korean writers also have a fascination with writing DID (Dissociative Identity Disorder) stories. Could it be that this is a Hyde and Jekyll type of story?
