When a mysterious figure appears in Three Pines one cold November day, Armand Gamache and the rest of the villagers are at first curious. Then wary. Through rain and sleet, the figure stands unmoving, staring ahead. From the moment its shadow falls over the village, Gamache, now Chief Superintendent of the Sûreté du Québec, suspects the creature has deep roots and a dark purpose. Yet Gamache does nothing. What can he do? Only watch and wait. And hope his mounting fears are not realized. But when the figure vanishes overnight and a body is discovered, it falls to Gamache to discover if a debt has been paid or levied. Months later, on a steamy July day as the trial for the accused begins in Montréal, Chief Superintendent Gamache continues to struggle with actions he set in motion. "This case began in a higher court," he tells the judge, "and it's going to end there."
