The Eternal Pirouette

Day 1: I love my new apartment. The woman across the alleyway is a dedicated ballerina; I can see her silhouette spinning beautifully in the living room. Day 2: She is relentless. Another storm is raging outside, yet she continues that hypnotic, rhythmic turn without a break. Day 3: The gale-force winds finally died down, and her window slammed shut. The dancing stopped. Day 4: The police are knocking on my door. They're asking how I didn't notice a corpse decomposing across the street.
