March in Montreal: It is a bitterly cold night and in the eerie silence of an old church forensic anthropologist Dr Temperance Brennan digs carefully, exhuming the remains of a nun who died in 1888. Why has the coffin been disturbed? And what will Tempe discover when she lifts the rotting lid? Just hours later, Tempe is called to the scene of an horrific arson: a young family has perished in mysterious circumstances. From the ruins of their house, to a trail of sinister cult activity and a terrifying showdown, Tempe gathers her evidence and confronts the terror of a killer out of control. "Another day. Another death. Death du Jour. My God, how many such days would there be?"
