Vampires vs Faith

It recovered quickly, crouching and spreading long arms that ended in claw-tipped fingers to either side with a hiss of rage.
I drew my pentacle into my fist, raised it like every vampire slayer you ever saw does it, and said, "Jesus Christ, lady. I just came here to talk."
The vampire hissed and started toward me with a gangling, weirdly graceful step. Its clawed feet were still wearing the three-hundred-dollar black pumps.
