Sir Sir

First, this is my first post on AO3, second, English isn't my native language. I don't have fixed date of posting, don't force me <3 (don't be weird I'm a minor)_____Lille, France, what a beautiful city, right? Even more beautiful when a dangerous potential serial killer is running through the streets like how students run to school! Everyone's terrifying, especially women since this criminal seems to only kill them, but not Alexander, Liam, Luka or Samantha!Theses four are like fingers on the hands. They know eachother since preschool and all became cops, so it's not a murderer who gonna stop them! Right? But, damn, the murder is very clever! The cops can't find any suspects! The victims don't have any common things unless being women!But nothing is impossible! They're gonna find the criminal, even if it would mentally broke them!
