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 the creature's shadow falls over the village, Gamache, now Chief Superintendent of the Sûreté du Quebec, suspects it has deep roots and a dark purpose. Yet he 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 that bitter November from which there is no going back. More than the accused is on trial. Gamache's own conscience is standing in judgment.
