Mara returned home late expecting quiet darkness inside her house. She noticed the front door standing open against the wind. Inside smelled of copper and something sickeningly sweet and stale. Her husband lay motionless on the kitchen floor near pills. His phone glowed beside his body showing one unsent message. Mara dropped her keys and screamed for the neighbors upstairs. Sirens arrived minutes before anyone could explain the locked door. Then the detective noticed footprints leading toward the bedroom window.
