Description
THE DAGGER OF JEALOUSY
Book summary
This book meticulously reconstructs the crime of Denisa, a 17-year-old girl murdered in Alcorcón in 2018 by Rocío, the new partner of her ex-boyfriend. Through a fast-paced narrative, the reader witnesses the police investigation which, thanks to an unusual stroke of luck, managed to solve the case within hours. The work combines the rigor of true crime with an implacable social analysis, offering a raw vision of jealousy, juvenile violence, and the Spanish judicial system.
What is it about?
On the night of the crime, Rocío, gripped by a fit of jealousy upon believing that Denisa had contacted her partner, forced Mario to drive her to the victim's house, where she stabbed her to death. The book follows the work of the Police, who solved the case thanks to a coincidence that prevented the homicide from going unpunished. Throughout its pages, the development of the judicial investigations, the interrogations of the suspects, and the trial sessions are reproduced, where an intense legal struggle is waged between the defense, the prosecution, and the public prosecutor's office. Furthermore, the work portrays the social environment of those involved: a group of disenfranchised young people, marked by sexual promiscuity, drug use, and the toxic use of social media as a tool for communication and threats. As a backdrop, it explores the tormented suffering of Daniela, Denisa's mother, a woman marked by a tragic destiny since her childhood in Romania.
