Dark Magic (Harbinger P.I.) (Volume 3)

Zombies on Main Street. Not my finest moment. The police aren’t exactly thrilled with me, but when a cold case heats up and starts to stink of the supernatural, suddenly the sheriff is in my office offering me a job. When the case hits boiling point, I’m dealing with monsters, black magic, and ritual killings. I even have to call on the two craziest witches in town for help. Things must be bad if the Blackwell sisters are my only hope for survival. Maybe I've bitten off more than I can chew. After all, those who fight monsters should beware that the monsters aren’t frog-faced, soul-eating demons.
