In the lakeside forest, the body of an unknown woman was found, who was killed by falling from a cliff. It seems that she led a strange lifestyle and never took care of her health: her feet did not wear shoes, her teeth were in terrible condition, and there was a poorly healed burn mark on her face. It was on this trail, when the police were already desperate to establish her identity, that she was identified by a former nurse at a boarding school for the feeble-minded. She identified it to her own horror: after all, she was sure that the deceased and her twin sister had died at a young age twenty years ago... Sarah Blädel was four times named the most popular novelist in Denmark according to the results of a reader vote. She is the owner of the country's highest literary award, the Golden Laurel. The fame of the “queen of the Danish detective story” extends far beyond the borders of her homeland and Scandinavia in general; Bladel's books are international bestsellers published in thirty-seven countries.
