El Doctor Centeno (Tomo I)

A young, physically slight protagonist struggles through urban poverty and attempts to improve himself, observed by an ironic narrator who alternates close, comic detail and reflective commentary. Scenes follow his quotidian tasks—mealtime improvisation, scavenged belongings, and small triumphs such as smoking a found cigar—while situating him in the cityscape and social milieu. The narrative examines education, ambition, and social rank, with realist description and satirical tone revealing the gap between imagined heroism and everyday survival.
