However, Commissario Andreotti is very pleased that this fateful event occurred because the expertise of a violinmaker could shed some light on a difficult murder investigation. Sophia’s curiosity is awakened. But then Luigi Maggio, Sophia’s childhood sweetheart, becomes the focus of the investigation. Another reason for Sophia to energetically help the languid Andreotti.
