The rain fell in sheets. Darkness swallowed the empty street. A shadow moved without sound. Footsteps echoed on wet stone. The door creaked slightly open. Light flickered from inside now. A hand gripped the knife tight. Blood dripped onto polished floors. Someone gasped in the hall. Then came the final scream.
