A web comic

I remember a web comic I saw on r/comics a few times that I read a few chapters off. I want to find it again but can't remember what it's called.

It was about two people solving crimes. one of them had a supernatural ability that caused hands to cover het face. And when she used it she could see like ghosts of people who were lying.

It was called something like "the sound of lies" in my head. But I can't remember what the actual name was apart from "the X of Y"
