Une chanson douce

Unlike the former employee who accompanied her, Kate managed to escape the flames that ravaged the family factory of copies of old furniture and the adjoining building where precious antiques were stored one night. The young woman lay unconscious and seriously burned on a hospital bed. For the police investigating the strange explosion that caused the fire, she is no less suspicious: what was she doing there at such a late hour, she now works as an accountant for one of the largest audit firms? Hannah, Kate's sister, refuses the too hasty conclusions. She is ready to go and look for the key to this disturbing riddle under the ashes, but far from imagining what awaits her... The sweet melody of the past quickly becomes stubborn when the queen of suspense takes us to the heart of a fascinating family mystery, haunted by an unscrupulous killer.
