The Darkest Day is the first novel in the five part Inspector Barbarotti series from renowned Swedish crime author Hakan Nesser. It's December in the quiet Swedish town of Kymlinge, and the Hermansson family are gathering to celebrate father Karl-Erik and eldest daughter Ebba's joint landmark birthdays.

But beneath the guise of happy festivities, tensions are running high, and it's not long before the night takes a dark and unexpected turn . . . Before the weekend is over, two members of the Hermansson family are missing, and it's up to Inspector Barbarotti - a detective who spends as much of his time debating the existence of God as he does solving cases - to determine exactly what has happened.

And he soon discovers he'll have to unravel a whole tangle of sinister family secrets in the process . . .
