Fegan has been a "hard man," an IRA killer in northern Ireland. Now that peace has come, he is being haunted day and night by twelve ghosts: a mother and infant, a schoolboy, a butcher, an RUC constable, and seven other of his innocent victims. In order to appease them, he's going to have to kill the men who gave him orders.
Aimee Leduc, a Parisian private investigator, has always sworn she would stick to tech investigation no criminal cases for her. Especially since her father, the late police detective, was killed in the line of duty. But when an old Jewish man approaches Aimee with a top-secret decoding job on behalf of a woman in his synagogue, Aimee unwittingly takes on more than she was expecting.
Aimee Leduc is happy her long-time business partner Rene has found a girlfriend. Really, she is. It's not her fault if she can t suppress her doubts about the relationship; Rene is moving way too fast, and Aimee's instincts tell her Meizi, this supposed love of Rene's life, isn t trustworthy.
