Rain hammered the silent street. A scream pierced midnight air. Detective Mara arrived too late. The victim lay quite still. Blood pooled beneath her hand. A bloody knife gleamed nearby. No witnesses stood in shadows. Mara knelt beside the corpse. "Who killed you?" she whispered. The clock inside stopped ticking. A note read, "You're next."
