 Late in life, Pérez Galdós began a career as a dramatic playwright.His most notable plays include "La Loca de la Casa" (The Crazy Woman of the House), "Hija de San Quintin" (The Daughter of San Quintín), "Electra" (whose opening sparked a riot) and "El Abuelo" (The Grandfather), which was adapted into a 1998 film by José Luis Garci.Galdós's theater works are characterized by sincerity and non-conformism; although contemporary at the time they were written, some of his theater works sound dated by current standards.
