A horrific murder has taken place. A woman has been mercilessly mutilated. And she was Cain's friend! Mortified and perplexed, Captain tries to approach the case professionally. It seems that the murder was done by a copycat, aiming to imitate the work of Emmanuel Pasquet, a demonic serial killer. And Cain has a suspect in mind: her husband and his old friend Abel!

Being personally involved in a horrific murder case, Cain gives his best in order to keep an opened mind and a professional approach when solving it. On the top of that, he risks losing the person closest to his heart, Gaelle.

A new murder case brings Cain and Lucia to the Convent of the Annunciation. Apparently, one of the nuns has committed a suicide.

However, Cain senses that the nuns are tormented by another, more complex and insidious secret...

A surgeon has been murdered. During the investigation, Cain comes face to face with the neurologist responsible for amputating his leg six years prior. Moreover, the cop discovers that the clinic being investigated is experimenting with a new treatment. On human guinea pigs!
