Book "The Centaur of the Marshes"

"In the Marshes of the Guadalquivir, a silence reigns, broken from time to time by the different notes of the sea left in the air by the mallards and the wigeons. The neighing of the horses and the burbling of the bulls that populate it resound under the blue sky at night, inciting them to challenge each other over great distances. Thus begins this fascinating story by Ángel Peralta, which was to be starred in the film by the beautiful Hollywood actress, Ava Gardner."
