The Vigilante...

I witness them all. The crimes done in the night. The child cowering in a corner, the little old lady bludgeoned to death, the girl falling under her rapist's weigh. But alas, I can't help them then.
As I plunge my knife into the pervert's heart, I feel his confusion. He doesn't know how I know.
I shove him aside and steal to my next target. I have little time before going to work.
You see, my nightly out of body experiences make me the best vigilante in the neighbourhood. I see everything from above.
One down. Two to go.
