The book has a slightly torn paper cover

Lars Kepler comes with a thrilling detective series — under a new pseudonym!

Private investigator Julie Stark receives an unannounced visitor at her office. Per Günter Mott, who is one of the owners of the successful family business, attended the company's board meeting the previous day and dined at his estate in northwestern Sweden. In the morning, he found a photo of a bloodied, tied-up man with a bag over his head in his mobile phone. However, due to memory lapses caused by the large amount of alcohol consumed, he has no idea how the picture got to his phone and who is captured on it. Fearing for his reputation, Per Günter wants to hire Julia to clear his name before the police get involved.

Julie asks her ex-husband, Sidney Mendelson, who works for the city police, to take time off to help her with the investigation. She still has a little hope that this might be a chance to win him back. Julie and Sidney go together to a luxurious mansion, where they gradually get to know all the members of Per Günter's family. And as it soon turns out, each of them has a secret.
