Resumen
El abuelo (The Grandfather) is a novel-in-drama form by Benito Pérez Galdós, one of Spain’s greatest realist writers.
Structured in five "jornadas" (acts), it blends narrative fiction and theater, focusing on themes of honor, lineage, truth, and redemption.
The story revolves around a nobleman, Don Rodrigo de Arista-Potestad, who returns to Spain from America in his old age after learning that his son has died and left behind two daughters—only one of whom is his legitimate granddaughter.
The central conflict lies in Don Rodrigo’s desperate need to know which girl carries his bloodline, to preserve the honor of his noble house.
