Praise for The Madness of Crowds

“This series has always excelled... This new novel grapples successfully with the moral weight of its narrative… ‘All Will Be Well’ never sounded so menacing.”
—The New York Times Book Review

"Intelligent and emotionally powerful.”
—Wall Street Journal

“The best mysteries and thrillers rise to the level of social novels, presenting readers opportunities to confront the difficult issues we face. Penny’s novels have always been driven by this (as well as the love of family and friends). The Madness of Crowds may be one of Penny’s darkest works, but we can still find comfort in the natural beauty of Three Pines and the quirky residents we would love to have as our neighbors.”
—Washington Post

“Timely and thrilling… faithful readers know that one of Penny’s books is less a single-serving crime tale than a full spread of fiction. The mystery may be the main course, but the side dishes — the food for thought, and the food at the Bistro; the people and their lives and, yes, loves; and certainly the setting itself — combine to create a full banquet for readers, one liberally seasoned with dry humor. The Madness of Crowds is one of the richest and most satisfying banquets yet.”
—St. Louis Post-Dispatch

“The mystery part of the books is always compelling and provides narrative drive, but Penny’s books are so rich because she provides real food for thought and gives those thoughts emotional grounding… another brilliant entry.”
—Mystery Scene Magazine

“Louise Penny, who in her seventeenth installment in the beloved Armand Gamache series, has tackled COVID and its consequences head-on. The book describes how everyday life in the tiny hamlet of Three Pines has changed while also exploring the threat of a statistician who is using the pandemic data as ammunition for a eugenics program. Plus one for the Canadians.”
—CrimeReads

“Penny’s optimism about the future shines brightly through Gamache’s family and Three Pines, and hopefully will shine into your heart as well.”
—BookTrib

“It’s easily one of the best mystery novels (or novels of any genre) in recent memory.”
—BookPage (Starred Review)

“Provocative… brilliant… Seamlessly integrating debates about scientific experimentation and morality into a fair-play puzzle, Penny excels at placing her characters in challenging ethical quandaries. This author just goes from strength to strength.”
—Publishers Weekly (Starred Review)

“Always a master plotter, Penny brilliantly combines this main story line with a profusion of subplots that bring together multiple interconnected themes, all raising thought-provoking questions about ethics and human relationships in a post-COVID world. Gamache's longtime belief in our common humanity is severely tested here, but, finally, it is that belief and the actions deriving from it that seem to offer the only balm for our lingering bruises.”
—Booklist (Starred Review)

“This book has layers within layers: good versus evil; our duty to the weak; the nature of power; the fact that good people are not always likable, and likable people are not always good. Highly recommended...”
—Library Journal (Starred Review)

“With The Madness of Crowds, [Penny] is one of the first crime fiction authors to tackle the pandemic and its aftermath head-on and in doing so becomes almost a literary Oracle at Delphi, mapping out both the rewards and the pitfalls facing society after such an unprecedented and seismic pandemic. In the end, The Madness of Crowds stands as one of the best novels in Louise Penny’s excellent, and now iconic, series.”
