"The next novel in the Chief Inspector Gamache series"-- Provided by publisher

"You're a coward." Time and again, as the New Year approaches, that charge is leveled against Armand Gamache. While the residents of the Quebec village of Three Pines take advantage of the deep snow to ski and toboggan, to drink hot chocolate in the bistro and share meals together, the Chief Inspector finds his holiday with his family interrupted by a simple request. He's asked to provide security for what promises to be a non-event. A visiting Professor of Statistics will be giving a lecture at the nearby university. While he is perplexed as to why the head of homicide for the Surete du Quebec would be assigned this task, it sounds easy enough. That is until Gamache starts looking into Professor Abigail Robinson and discovers an agenda so repulsive he begs the university to cancel the lecture. They refuse, citing academic freedom, and accuse Gamache of censorship and intellectual cowardice. Before long, Professor Robinson's views start seeping into conversations. Spreading and infecting. So that truth and fact, reality and delusion are so confused it's nearly impossible to tell them apart. Discussions become debates, debates become arguments. As sides are declared, a madness takes hold. Abigail Robinson promises that, if they follow her, ça va bien aller. All will be well. But not, Gamache and his team know, for everyone. When a murder is committed, it falls to Armand Gamache, his second-in-command Jean-Guy Beauvoir, and their team to investigate the crime as well as this extraordinary popular delusion. And the madness of crowds.
