The Greek myths have inspired legions of writers who have seen in them the inexhaustible source of the legends of the Antiquity which have been transported to our days thanks to the ability of their pens. Among the best known examples we could cite Shambleau, written by the wonderful C. L. Moore, but this is not the only case. José Caballero, who is already known by the followers of our books (remember his The Last Days of Vlad the Impaler), is now entering the mysterious terrain of the myths. In this case in particular, that of the Gorgons. Narrated with the same style as Bram Stoker's Dracula (a succession of texts ranging from letters to newspapers, news in the press, or telegrams), the author introduces us to a mystery that, although it seems indecipherable, ends up having a solution. Set in the Greek Islands (we assume, given the knowledge of the world that our author has acquired because of his incessant travels), their representation will be as realistic as possible. Caballero also takes us to Edinburgh and to London, where the investigators' inquiries will, step by step, unravel the enigma that surrounds the characters, especially the female ones, which cover the pages of this novel. Mystery after mystery, we find a scientific research expedition staged to solve the problems of a British nobleman, which ends up finding and solving issues that were beyond not only its scope, but also its knowledge. As it is always the case, a work more than recommendable and quite entertaining, in addition to being superbly written.
