The New York Times bestselling Cork O'Connor Mystery series--a "master class in suspense and atmospheric storytelling" (The Real Book Spy)--continues with Cork O'Connor revisiting a case from his past and confronting mysterious deaths in the present. A few nights before Halloween, as Cork O'Connor gloomily ruminates on his upcoming birthday, he receives a call from his son, Stephen, who is working for a nonprofit dedicated to securing freedom for unjustly incarcerated inmates. Stephen tells his father that decades ago, as the newly elected sheriff of Tamarack County, Cork was responsible for sending an Ojibwe man named Axel Boshey to prison for a brutal murder that Stephen is certain he did not commit.
Cork feels compelled to reinvestigate the crime, but that is easier said than done. Not only is it a closed case but Axel Boshey is, inexplicably, refusing to help. The deeper Cork digs, the clearer it becomes that there are those in Tamarack County who are willing once again to commit murder to keep him from finding the truth.
At the same time, Cork's seven-year-old grandson has his own theory about the investigation: the Windigo, that mythic cannibal ogre, has come to Tamarack County...and it won't leave until it has sated its hunger for human blood.
