Hexed Hit

I'm getting tired of dead bodies showing up every time I turn around. One-ew. And two-I'm so not qualified for this.
I mean, this was supposed to be a magical drug bust. Easy peasy.
But with my plucking luck, I walk right in and stumble over a dead body.
This body belongs to a dealer who was worse than most. She took advantage of mixed breed shifters who were more powerful than they realized; she stole magic and got on the bad side of my favorite dragon.
Bennett's raging and I need to solve this case before he goes off the deep end.
A rookie against dealers and addicts is not good odds.
But it gets worse.
Because the killer knows how to hex.
Hexing uses magical equations to do the dirty work ... and I hate math ... well, math and murder.
