Beneath a scorched summer sky, the wealthy Finney family have gathered at a lakeside manor to honour their late father. But when the heat wave boils over into a mighty storm, a dead body is left in its wake - and Chief Inspector Armand Gamache finds himself with a building full of suspects.

Wealthy, cultured and respectable, the Finney family is the epitome of gentility. When Irene Finney and her four grown-up children arrive at the Manoir Bellechasse in the heat of summer, the hotel's staff spring into action. For the children have come to this idyllic lakeside retreat for a special occasion - a memorial has been organised to pay tribute to their late father. But as the heat wave gathers strength, it is not just the statue of an old man that is unveiled. Old secrets and bitter rivalries begin to surface, and the morning after the ceremony, a body is found. The family has another member to mourn. A guest at the hotel, Chief Inspector Armand Gamache suddenly finds himself in the middle of a murder enquiry. The hotel is full of possible suspects - even the Manoir's staff have something to hide, and it's clear that the victim had many enemies. With its remote location, the lodge is a place where visitors come to escape their pasts. Until the past catches up with them.
