"May the curse I cast on all of you tonight follow you and your descendants unto the end of time. May none of you ever find peace again." - Johannah Donnelly's dying words.

On the night of February 3, 1880, a vigilante mob killed five members of the Donnelly family in the most notorious mass murder in Canadian history. The mob, led by the local constable and inspired by the parish priest, clubbed, shot, and hacked their victims to death and then set their farmhouse ablaze. No member of that mob was ever punished. At least not in a court of law. Instead, the killers face a more terrifying justice that reaches out from the grave to defy distance and time. From the dense bamboo forests of China to the dark pine forests of Canada, the watery depths of the Great Lakes to the Russian port of Arkangel, Beacon Hill to a remote fire tower in Montana, the relentless horror of Johannah Donnelly's curse stalks the killers and their offspring. Using a combination of previously undiscovered documents and spine-chilling eyewitness accounts, this gripping novel exposes a frightening new history of the Donnelly murders and the haunting consequences that followed.
