In 1989, a killer dumped the body of twenty-year-old Lucie Martin into a picturesque lake in the West of France. Fourteen years later, during a summer heat wave, a drought exposed her remains -- bleached bones amid the scorched mud and slime. No one was ever convicted of her murder. But now, forensic expert Enzo Macleod is reviewing this stone cold case the toughest of those he has been challenged to solve. Yet when Enzo finds a flaw in the original evidence surrounding Lucie's murder, he opens a Pandora's box that not only raises old ghosts but endangers his entire family.
