Jordi Sierra i Fabra returns with a powerful thriller of huge relevance: the objectification of women, evictions, corruption, the construction industry, the new wave of politicians, poorly paid jobs, the financial crisis... A woman is thrown into the Llobregat river, near its mouth, in the middle of the night. She is naked and has been beaten and murdered. She is young and more than pretty: she is disturbingly beautiful. Even dead, her morbid allure is obvious. The two officers put in charge of the case will soon understand that it is that very same beauty that caused her death. As the investigation begins, trying to identify the dead woman, five characters move across the pages of this hypnotic and absorbing thriller, each one hiding something, each weighed down by their secret and with a guilty conscience. Which of them is the killer?
