TL;DR: The Hunt Behind the Hunt
A poisoned water supply was never the endgame.
It was bait.
Gamache realizes that a murdered biologist left a trail pointing to a larger conspiracy involving organized crime, political fixers, and a plan to justify an American annexation of Canada.
The real enemy is not just a criminal network but a single manipulator hiding in plain sight.
Key takeaways:
- The initial poisoning case was a distraction from a resource-based invasion plan.
- A hidden notebook and a remote northern lake reveal an execution tied to political power brokers.
- The true mastermind uses the Prime Minister as a shield while positioning himself to lead an emergency government.
- The story ends with the immediate threat stopped but the long-term water crisis unresolved.

Spoiler warning: This section recounts the complete plot, including the ending.
Check out our detailed chapter-by-chapter breakdown of This Book
The novel opens after the water-treatment plant explosion. Gamache is recovering from injuries that left him partially deaf. He is haunted by the feeling that the team made a serious mistake.
They believed they stopped a plot to poison Montréal’s drinking water. But the murdered biologist, Charles Langlois, left behind a second notebook.
This notebook was not a conclusion. It was a decoy.
The real plan is darker. Langlois hid a cryptic map containing numbers and symbols. The map points to a remote northern lake he visited several times before his death.
Isabelle Lacoste and environmental biologist Vivienne LaPierre fly to that location. They find the body of Frederick Castonguay. He was the executive assistant to Jeanne Caron, a high-ranking political fixer.
Castonguay was shot once in the back of the head. It is a professional mob execution. The order likely came from Joseph Moretti, head of the Montréal mafia.
The investigation expands. Journalist Shona Dorion, who blames Gamache for her mother’s death, uncovers evidence of massive bribes.
These bribes flowed through an environmental group called Action Québec Bleu. The money facilitated the illegal sale of Canadian industries to American corporations.
The plot connects to a technology called FEDS. It stands for Fire Event Detection Suite. This system can predict the flow of ash from megafires.
Gamache makes a risky move. He brings convicted conspirator Marcus Lauzon to Three Pines for a Sunday lunch. Lauzon claims he was a pawn. He hints that Prime Minister James Woodford is the true mastermind.
This leads Gamache to a secret meeting at the Haskell Opera House. The building straddles the US-Canada border. American General Bert Whitehead reveals the existence of War Plan Red.
This updated military plan outlines an American annexation of Canada. The goal is to secure freshwater resources as the United States faces a terminal drought.
The conspirators strike back. A social media campaign paints Gamache as a delusional, brain-damaged old man. The team must work while being publicly discredited.
Gamache, Lacoste, and Shona infiltrate Parliament during a lockdown. An assassination attempt on the American President was a setup.
The wildfires were meant to be framed as Canadian aggression. That would justify an American invasion.
The final reveals come quickly. Jeanne Caron and Joseph Moretti were executing the plan. Evelyn Tardiff, once suspected, was actually a deep-cover CSIS informant.
The Black Wolf is Marcus Lauzon. He manipulated everyone. He used the Prime Minister as a shield. He used the mafia as an enforcer. He planned to lead an emergency government after the chaos.
Gamache and his family, including his son Daniel, perform a citizen’s arrest on Lauzon in Three Pines. The immediate plot collapses.
The book ends with a sobering thought.
The water crisis remains. The Americans will eventually run out. One day, they will have to come.
