Cain

Nothing is settled between Caïn, Lucie, and Legrand. A murder investigation involving a soldier reignites tensions, as Lucie's deep ties to the military clash with Caïn's anarchist views. The arrival of Marie Saint-Hilaire, Lucie's former section leader, may help the investigation inside the regiment - though Caïn remains skeptical.

Psychic Sandra Vernon arrives at the SRPJ claiming she witnessed a murder in a vision. Caïn mocks her story until a real disappearance matches her account. The investigation points to a garage owner suspected of targeting women, but evidence is scarce. As another crime occurs, Caïn must navigate a case balancing forensic science, the occult, and his growing curiosity about his future with Lucie.
