Les clavegueres de l'estat is a rigorous and documented essay that contains shocking revelations about the maneuvers that during the last government of Mariano Rajoy have been carried out by the Ministry of the Interior to fight against political opponents, be they pro-independence or members of Podemos. Written by Jaume Grau, scriptwriter of the documentary The Sewers of Interior, the book explains, with testimonies hitherto unpublished, what has been the extent of the dirty war that the Partido Popular government has carried out in the last five years, and the ties that this dirty war has with different open cases about corruption. On the other hand, a line of continuity is established rigorously between the bad practices of some members of the police and the judiciary during the Franco regime and to this day. Finally, a historical comparison of the dirty war practices in different periods and nations is discussed, putting it in relation with the structure of the sewers in the Spanish state.
