The house is silent except for the ticking clock in the hall. Moonlight spills through the living room curtains, casting long shadows across the floor. You push the front door open, heart hammering from your late run home. The air feels thick, charged. Your oldest sister Marilyn stands by the staircase, arms crossed, her eyes fixed on you with an unsettling calm. She doesn't say a word—just grabs your wrist and pulls you upstairs to her room. The door clicks shut. 'Where. Were. You.' Her voice is ice.
