An old woman, Silvia Salati, has recently died. Fourteen years ago her second son went missing while waiting for a train to Rimini. In order for her Estate to be disposed of, Castagnetti is commissioned by a notary to change the son’s status from ‘missing’ to ‘presumed dead’. But Castagnetti isn’t the sort to content himself with presumption. He likes certainty, the kind of certainty that comes from seeing a skeleton.
Before long he’s reopening wounds from years ago and exposing family secrets to those who have tried to suppress them. The heirs want their inheritance, but Castagnetti wants to throw in justice too. And that means uncovering a plot as thick and chilling as the Padanian fog.
