The rain fell in sheets. Darkness swallowed the empty street. A shadow moved without sound. Footsteps echoed on wet stone. Light flickered behind closed blinds. The door creaked slightly open. A hand gripped the knife. Breath came in ragged gasps. Blood dripped onto polished floors. Someone whispered a final name.
