Ireland 1963. As the Irish people prepare to welcome President John F. Kennedy to the land of his ancestors, a German national is murdered in a seaside guesthouse. Lieutenant Albert Ryan, Directorate of Intelligence, is ordered to investigate.
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.
Aimée Leduc is happy her long-time business partner René has found a girlfriend. Really, she is. It’s not her fault if she can’t suppress her doubts about the relationship; René is moving way too fast, and Aimée’s instincts tell her Meizi, this supposed love of René’s life, isn’t trustworthy.
