Is the castle of Trevejo the living vestige that confirms the mythical relationship between Templars and Masons? What were the Civil War and the post-war periods like in Acebo? Was the horrible crime between families that took place in San Martín de Trevejo fair? Who were those persecuted by the Holy Office in Perales and Hoyos? The answers to these questions, and others, are revealed throughout the successive passages that make up this work, where the reader can immerse himself in the past, crossing the frontier of time. This new work by B. Maestro is the story of those who suffered from unemployment and the bad conditions of an iniquitous life, but it is also the story of those who revealed themselves and fought so that this circumstance would change, without forgetting those who defended the democratic government in its day, even when they were the ones who put an end to it. In the pages that make up this work of historical research, the reader will be able to immerse himself fully in a turbulent Contemporary Age, covering its totality, and dividing the chapters following the order of the centuries that conform it (XVIII, XIX and XX).
