"The air is unbearably tense as Armand Gamache returns to the Surete du Quebec for his first day of work since being demoted from its command to head of homicide. Amid blistering personal social media attacks, Gamache sets out on his first assignment. He has been tasked with finding a missing woman, but while he leads the search for Vivienne Godin, Three Pines itself is threatened when the river breaks its banks, and a province-wide emergency is declared. As the waters rise, a body is discovered - and the victim's distraught father contemplates a murder of his own. Gamache is a father himself, and is haunted by a question ... what would he do, if his child's killer might walk free?"--Publisher description
