Rain hammered the empty, dark street. Footsteps echoed through silver puddles. A scream fractured the midnight silence. Blood shimmered on the pavement. A red glove lay abandoned. Police sirens wailed in distance. A figure vanished between shadows. Neighbors peered through drawn curtains. Detective Quinn arrived, coat dripping. He knelt beside the body.
