The Raven And The Dove

A girl is... dead? But why does this feel so familiar? A criminal is on the loose, but, why is it impossible to catch him?
A string of murders target this city/I hope they feel what I felt/Threats to the X group?

Still writing this tbh but it's about a detective's journey to solving the case of a killer. However, this is not a simple case, as it could ONLY be solved by the legends.
