We tried. I sensed movement and turned in time for a corpse to tackle me full on and send us both crashing to the floor. My wands were instinctively doing theSectumsempra curse as I sliced toward the jaw, trying to keep its teeth off of me, but it moved and I instead transected the throat. Black, dead blood splashed across my face in a luke-warm thick-liquid rush, blinding me for a second. I could feel it jerkily moving over my body, legs straddling my hips. It was dead, and I was grateful to realize that the corpse only wanted to kill me in this position.
