Too Late For Sorry, Mom

I tried to warn Mom about my stepsister’s scammer fiancé, but she beat me to death for being "jealous." As a ghost, I watched her tape my bedroom door shut, mistaking the stench of my rotting corpse for a bitter tantrum. They handed their fortune to the con man, celebrating while I decayed just a wall away. When they finally break down that door and find my diary, will the horrifying truth drive my abusers completely insane?
