The main character of this novel, Inés, has recently come out of a fifteen year imprisonment, works as a eco-friendly pest-controller and tries to live a peaceful life catching up with the cultural alienation caused by her time in prison. However, one of her clients, who seems to be aware of the fact that Inés killed her husband’s lover, requests her help to do the same thing. When Inés’s friend, a private detective she met in prison, starts looking into it she realises that the client might have different intentions.
 
Time of the Flies, like much of Piñeiro’s writing, is concerned with the intersection of gender and violence. Piñeiro writes women who are not victims of their circumstances: her characters are resilient, complex and have a reasonable desire for revenge. Through them, and with writing that is direct, tense and impactful, she leads the reader to questions about the social norms we accept without questioning them and the morally grey circumstances that we often navigate, especially as women. 
 
Time of the Flies offers a rich social commentary as well as an education on flies, a mystery that keeps twisting and turning and a story about friendship.
