I spat a curse and ran down the hall after it. The hamstrung officer lay on the floor screaming, and the other man, the one who'd had his spine ripped out, was choking and twitching, unable to draw in a breath. Red anger flooded me, rage that I realized with some dim part of my mind was as much a part of the beast and its blood-maddened frenzy as it was of me.
I rounded the corner in time to see Murphy, standing in front of a litter of bodies, take a last shot at the loup-garou. And then it snarled and she vanished underneath its bulk.
