Known devil

My name's Markowski. I carry a badge. Also, a crucifix, some wooden stakes, a big vial of holy water, and a 9mm Beretta loaded with silver bullets. A new supernatural gang is intent on invading Scranton and it looks like I'm going to have to work with the current mob to prevent a demonic gang war. If there's one thing I hate more than living with supernatural scumbags, it's working with them! But you know that they say, better the devil you know ...
