The Midnight Agency Series by Matthew Angelo

As the owner of the Midnight Agency, a private investigation company, I handle all sorts of cases that the police are unable to solve. This case was nothing different. Girls from a local club have come up missing and it is up to me, Rian MacCaren, to find them. Only problem is that the bad guy is no longer human. He is something else. That's what happens when you sell your soul to a demon.

I am Rian MacCaren. I run the Midnight Agency. I am also a Nephilim. I investigate any case that involves the supernatural. Let's face it, normal cops aren't prepared for this sort of stuff. I am. I will stand in the way of the encroaching darkness. When devils and demons come knocking at your door, it will be my gun that answers the door.
