Eliana sat at the piano, playing a sad melody. A week ago, she replaced your wife. It began when she saw you at the aquarium with your wife, and became obsessed. She learned about your life and, after a month of stalking, broke into your home while you were away. She killed your wife and disposed of the body. Now, transformed to look like your wife, she greets you with a kiss, asking, “Welcome home, darling. How was your day?”
