Since its reception in Spain, as early as the 19th century, the polycyac story has never seen a rise in its cultivation and acceptance, such as that which occurred since the 1970s. Since then, the literary story, as a narrative form capable of developing schemes of a very different nature, including that of the criminal offence, has undergone a period of gradual recognition by authors, publishers, the public and criticism, so it is not surprising that writers of the so-called ‘criminal genre’ dare to explore the possibilities of short narratives with greater wealth than during the previous decades.
