Rain silvered the harbor as Detective Vale found the body. It floated beneath the wooden pier, face turned toward dawn. Vale recognized the silver ring before seeing the woman's face. Her sister had worn it at dinner just last night. Around her, the waiting fishing boats knocked like patient clocks. The corpse's fingers were curled around a brass hotel key. Her telephone rang inside her coat, vibrating against her ribs. The screen showed her sister's name, then abruptly went dark. Behind her, someone whispered, “You should have stayed home tonight.” When she turned, only her own footprints marked the sand.
