Demonic Detective: Day One

There is a demon somewhere in the city, and the police chief Hazal Damir needs to find it before it kills anyone.
There is a woman in the city that has little grasp on what it means to be a human, and Jasper with Elvira need to teach her to behave before she kills anyone.
And all that tied nicely with a ribbon of a murder.
In which Robin is confused, Hazal is blindsided, and everyone else just goes with the flow.
