Island's Killer

POV Adrien:

After reading the letter, I checked the heads then Fei's body for 30 minutes then I covered her body and the heads

Luka, Zoe, Marinette and I went to the bar, the only place clean from blood after the tragedy happened in this island. Each one of us got a glass of liquor and we sat in the couch

Marinette: in the letter there isn't anyone mentioned as the killer

Luka: so, we are clueless

Zoe: the help is coming when?

Adrien: in three hours, and concerning the killer, I had known who

Everyone: whatttt?

Adrien: I'm late and I blame myself to know the solution for all those riddles. I really blame myself and I feel guilty

Luka: don't blame yourself, you are here not to work as an FBI but to relax and then you found yourself stuck with 18 dead body.

Marinette: Luka is right, you have resolved a lot, and you only had a day to resolve every riddle but you did really well

Zoe: don't feel guilty. But now tell us who is the killer

Adrien: Alya's message do you remember it?

Luka: the hoops and 86, we didn't understand.

Adrien: in the killer's letter, it says to look at it differently. What if the hoops mean double zero

Zoe: 0086? Means nothing

Luka: wrong, it's a China's phone prefix. You can write it +86 or 0086. France is +33 or 0033

Marinette: wait a fucking minute, it's Fei?

Adrien: yes, Fei is the killer

Zoe: wohoooo Adrien, Fei is a dead body too

Adrien: she suicided after killing all of them. also, Zeus #00255 means blue Zeus, right?

Luka: yes

Adrien: Zeus is known as the king of the Gods, also he is the God of the sky, lightning, thunder, and law. Don't you get it?

Zoe: hmmmm no

Adrien: something from what I mentioned is blue. What is it?

Marinette: the sky

Adrien: yes, and Fei's name means fly in the sky. She positioned herself as a scarecrow, but before she set her right hand, she drank a little bottle full of poison, and she died poisoned. I found this bottle with cyanide potassium and if you check the fingerprints, you will find Fei's. something else, if you remember she said that 22-18=4, and it has two meanings. number 4 in japan and china means death 

Luka: now all this nightmare is over, even if I lost my sister

Adrien: we were really dumb, we had to think about Fei first and thinking about it, there are a lot leading to her. first of all, it was her who decided first that we stay together (chapter1) then she was talking to Chloe alone, and I'm sure they were talking about taking our phones (chapter2), something else, how Fei known that the well don't have water unless she was there and it's her who put the phones there (chapter5). also, the day we saw Chloe, it was Fei wrapping herself into a black robe but she had Chloe's head above hers, and that's why Chloe was so tall. that's why we didn't find Chloe's head that day
