Detective Clara walked slowly up the gravel path at night. She reached the massive oak door and rang the bell. The door opened revealing a pale butler with trembling hands. She followed him into the dark study filled with silence. The murdered man lay dead upon the wooden study floor. A sharp knife was embedded deep within his upper chest.
