The predetermined course of historical events is changing - slowly, imperceptibly, but inevitably. Yes, the Third Crusade will take place, but no one knows what the consequences will be. No one except a handful of conspirators - the most influential people of the 12th century, eager to change the face of Catholic Europe. Soon the final, decisive blow will be dealt. And the main characters of A. Martyanov’s cycle “Messengers of the Times” - Michel de Farmer, Gunther von Reichert and Sergei Kazakov - will take part in the grandiose political performance, unfolding in the space from Barcelona to Constantinople.
