Klaus-Peter Wolf, born in Gelsenkirchen in 1954, lives as a freelance writer in the East Frisian city of Norden, in the same district as his inspector Ann Kathrin Klaasen. Like her, after many years in the Ruhr area, in the Westerwald and in Cologne, he moved to the coast and became an East Frisian by choice. His books and films have received numerous awards. To date his books have been translated into 26 languages and have sold over 15 million copies. More than 60 of his screenplays have been filmed, including many for Tatort and Polizeiruf 110 . The author is a member of the PEN Center Germany.
The novels in his series with Chief Inspector Ann Kathrin Klaasen regularly spend several weeks at number 1 on the Spiegel bestseller list. Several books in the series are currently being filmed for ZDF as major features, and continue to enthrall millions of viewers.
