El puñal de los celos

Denisa was 17 years old when she broke up with her boyfriend, after a year of dating, and began living with another young man. However, she found herself involved in a strange love triangle that included her ex-partner, Mario, and his new partner, Rocío, who was obsessed with the fact that Mario was still seeing her previous girlfriend. One cold and rainy night in November 2018, Rocío thought she saw that a friend request sent by Denisa had entered her boy's mobile phone. This caused her to have an attack of jealousy that enraged her to the point of making Mario take her in his car to Denisa's house in Alcorcón (Madrid), where he stabbed her with a knife that ended her life almost instantly. The Dagger of Jealousy is a faithful account of how the Police managed to clarify the crime in just a few hours thanks to an unusual coincidence, which prevented the homicide from probably going unpunished, and where the reader can follow the investigations and listen to the suspects both during interrogations and at trial.
