GOING TO KILL ERIK BERGMAN.
LET'S SEE IF YOU CAN STOP ME.

July 2007. A letter arrives on Inspector Barbarotti's doorstep detailing a murder that is about to take place in his very own town. But by the time the police track down the subject of the letter, he is already dead.

So when a second letter arrives, then a third, and a fourth, it's a game of cat and mouse to find the killer before they can make good on all of their promises.

Meanwhile, an anonymous diary is unearthed depicting the incidents of a group holiday in France five years earlier. And it doesn't take Barbarotti long to realize that the people within it are the ones whose lives now hang in the balance . . .
