A TONI DAMIANO MYSTERY Ten years ago, the prestigious suburban community of Beaconsfield, Quebec was shaken by the discovery of the bodies of an ordinary couple in their home. What appeared to be a common murder-suicide-- husband kills wife and takes his own life-- has baffled two previous investigations. At one point, the son, who had a tumultuous relationship with his father, was considered a suspect. Lieutenant Detective Toni Damiano and her partner, Detective Pierre Matte, attached to the newly-created Cold Case Unit, have reopened the case with their usual confidence and grit. They are met with unexpected challenges and a reality they've never had to face.
