They question him, hoping to get the name of Rémy's accomplice, but Silien tells them he wasn't the informant. He mentions that he hopes to get out of the criminal underworld and live in a house he has built in Ponthierry. It is revealed that the car that rescued Maurice has been found wrecked, with Thérèse's body inside. The police also suspect that Maurice killed Gilbert. They threaten to falsely implicate Silien in a drug case unless he helps them find Maurice. Silien complies and Maurice is found. Maurice claims that Gilbert was killed while Maurice was in another room of the house. The police offer to let him go if he has information on the robbery in Neuilly, but Maurice claims he has no information. He is jailed, where he meets a prisoner named Kern. Silien finds the buried jewels, money, and gun beneath the lamppost. He visits Nuttheccio's club and speaks to Fabienne, a former girlfriend. He offers to get her out of her relationship with Nuttheccio if she will testify that Nuttheccio and Armand killed Gilbert. She eventually agrees. Silien kills Nuttheccio and plants the jewels in his safe, while Fabienne calls Armand to tell him Nuttheccio has found the stolen jewels and wants to see him. When Armand arrives, Silien kills him too, staging the scene to make it look like they killed one another. With Nuttheccio and Armand dead and framed for Gilbert's murder, Maurice is released from prison. He still believes that Silien informed on him, but Jean and Silien tell him that Silien was not the informant and had in fact been maneuvering to get Maurice out of prison. Though Silien was a friend of Salignari, he did not inform him of the robbery. However, he recognised Thérèse as one of Salignari's informants. The night of the robbery, Silien called Salignari to invite him to dinner, and Salignari revealed that he would be arresting two burglars in Neuilly. Silien got the address from Thérèse and went to Neuilly to avert a disaster. He arrived in time to pick up Maurice and take him to Jean's apartment. Silien announces that he will be moving in with Fabienne at his home in Ponthierry, and that he is going there immediately. However, while in prison, Maurice arranged for his cellmate Kern to kill Silien, promising to give Kern the money he stole from Gilbert in exchange.
