Murder Club

After thwarting a crucial arrest, Amélia Delcourt, 32, who has just been promoted to the criminal brigade, finds herself ousted from the investigation into Shakespeare, a serial killer who has been active for ten years. When Juliette, 17, disappears, Amélia, convinced that it is a kidnapping, continues the investigation clandestinely. While visiting the teenager's parents, she meets Daniel Hansen, a famous media profiler who has fallen, who is already on the trail...

Reinstated in the Shakespeare cell, Amélia questions the girlfriend of Shakespeare's last victim, a survivor of the killer, and secretly uses Daniel's psychological skills to make her talk. Amélia and Fauvel then discover that the murder weapon belonged to a serial killer who was arrested more than ten years ago, sold at illegal auctions of objects linked to assassinations...

While Amelia struggles to find information about the Phantom Killer, Daniel goes to the abandoned house where he grew up and discovers with horror the corpses of the women left by his father, now senile. In addition, Amelia accompanies Daniel, who has received a strange invitation from Shakespeare to participate in a murder party. If the other players believe it is a set-up, they have understood the seriousness of the game: if they have not found Juliette within thirty minutes, she will die...

While Daniel is under arrest and everyone seems convinced that he is both Phantom and Shakespeare, Amélia is assailed by doubts and decides to confront him. He ends up confessing to her that his father is the serial killer Phantom. Shakespeare would therefore still be at large. From the DNA tests carried out on the bodies, the police notice that one of them stands out: François Castelli, the only man that Phantom has murdered. Amélia manages to get Daniel out of the police station and the two teammates go to question Castelli's ex-wife...
