The Grim Reaper's Trick or Treat

I'm the Grim Reaper. My best friend Eleanor was beaten to death by her husband. That night, I took over her body. By day, I learn to cook and sew, playing the "normal mom." By night, I put on my black robe and roam the town—teaching every abusive husband a lesson. Every woman here thinks I'm their guardian angel. They bring me candy every day. But they have no clue the angel they're worshipping is actually the Reaper who comes for the dead.
