"History pushes us to questions about its course, which we answer sometimes, and many times confusion remains a prisoner of souls and chance, until awakening comes to strike our consciences through one of those honest creations that refresh memory, such as the letter that Fernando Arrabal addressed in 1971 to General Francisco Franco (President of Spain 1939- 1975) to argue with him about the great Spanish Civil War - as some Spaniards described it - and then about the regime imposed by the general after the war. It is a cry for freedom and a spontaneous testimony from within the fence that shackled Spain in the furnace of war, turmoil, and dictatorship. The message was spread without interruption in France, Spain, and Argentina In many publications, the most recent of which was published in 2011. Sincere satire, pain and heartbreak over a lost homeland, eternal exile, in addition to the life of the writer Fernando Arrabal, which is full of creative productions in theatre, cinema, literature, poetry, chess, and others... All of this makes this book a journey to get to know - perhaps - On the conditions of Spain in the age of mourning.
