It's been more than a year since Los Angeles Police Department (LAPD) detective Jacob Lev learned the remarkable truth about his family, and he's not coping well. He's back to drinking, he's not talking to his father, the LAPD Special Projects Department continues to shadow him, and the memory of a woman named Mai haunts him. And while Jacob has tried to build a bridge to his mother, she remains a stranger to him, imprisoned inside her own tattered mind. Then he comes across the file for a gruesome unsolved murder that brings the two halves of his life into startling collision. Finding the killer will take him to Paris -- the city of romance, but also of gritty streets, behind the lights.
