The continued investigation determined that GHS was mining neodymium, a rare earth mineral, from a mine in Patagonia.

While Jean-Guy was talking to this guard, he noticed files being erased from his co-worker’s computer. Their suspicions seemed to be confirmed when Jean-Guy was confronted by a guard questioning why he was working on the weekend. Jean-Guy went to his office to see what he could learn by logging into a co-worker’s computer. They wondered if perhaps Stephen had found some evidence of an engineering flaw in items made by that company.

When looking through a box of Stephen’s personal items given to Armand at the hospital, he, Dussault, and Armand’s son-in-law, Jean-Guy Beauvoir discovered an agenda for the board meeting of GHS, an engineering firm for which Jean-Guy worked. Armand and Reine-Marie both realized later when the met with Claude Dussault, the head of the police in Paris and Armand’s friend, that he wore the same cologne. Armand tried to trap the killer in the apartment, but he escaped through a second door in the kitchen. Armand and Reine-Marie both smelled a hint of cologne in the air, proof that the killer might still be there. Inside they found the apartment had been ransacked and the body of Alexander Plessner, a man who Armand does not recognize, laying behind a couch. Armand and Reine-Marie next visit Stephen’s apartment to determine why he was not staying there. It appeared another man had been staying with Stephen in that suite.

The day after Stephen was hurt, Armand and Reine-Marie discovered that he had been staying in a suite in Hotel George V instead of his apartment in Paris. Armand’s loyalty to his godfather made him determined to find out who had hurt Stephen and why. Armand, who was with Stephen at the time, knew Stephen was hit intentionally. Armand, and his wife, Reine-Marie, were in Paris awaiting the birth of their new granddaughter when Armand’s godfather, Stephen Horowitz, was critically injured when he was hit by a delivery truck. In the novel All the Devils are Here, the last installment in Louise Penny’s Chief Inspector Gamache series, Armand Gamache confronts the devil within himself as his family is threatened by greedy, powerful professionals trying to cover up a fatal engineering flaw. The following version of the novel was used to create this study guide: Penny, Louise.
