I am quite intrigued on how the doctor guy with his special party thingies hasn’t become some sort of official suspect for interrogation, even if it isn’t likely he straight up commited the crimes himself. I do understand though, I’m pretty sure the goal in mind here is to avoid even persuing people who aren’t likely to be the murderer that directly head on, and instead focus on trying to get to the murderer themself as soon as possible. Cool.

I’m really intrigued on how this cop is going to be able to be undercover as a doctor, that sounds incredibly difficult to do, but that does add a strong level of [suspense?] to the story. I think this is going in an interesting route so far. 

This is quite a bit of an interesting story, depending on where it goes. I'm kinda intrigued on the direction, and I think it'll be nice once the structure of the story truly settles itself together
