Rain lashed the dark street. Shadows clung to cobblestones. A lone figure walked swiftly. Their cloak billowed in wind. They clutched something tightly. A door creaked open then. Footsteps echoed in hall. Silence swallowed the night. A struggle ensued briefly. Gasps were quickly stifled. A thud shook the floor. Stillness returned to room. Darkness held its secrets.
