German writer Christa von Bernuth was born in 1961. In 1999, her first novel “The Woman Who Lost her Conscience” (“Die Frau, die ihr Gewissen verlor”) was published. The second book, "Voices" ("Die Stimmen"), marked the beginning of a series of fascinating detective novels, united by a key character - the female police commissioner Mona Seiler. All the novels in this series, including the novel Then You Were Silent, offered to fans of action-packed detective stories, were filmed and received enthusiastic responses from the public and the press.

“...This case has now become her business, only hers, and no one will take it from her. She looked at the victim's open mouth and thought that the killer wanted to keep her silent even after death. She touched the pale, wrinkled skin, the lower abdomen, disfigured by many small gaping wounds, apparently inflicted by the tip of a knife. Clemens Kern was right, the killer became more and more cruel. She examined the floor around the corpse. There was relatively little blood, which meant that the perpetrator injured the victim after her death. The serial killer's handwriting was one hundred percent clear."
