This work investigates the specific influence of the Iberian Peninsula on the life and literary output of British novelist Graham Greene. Carlos Villar Flor, a scholar of English literature, utilizes archival research and biographical analysis to reconstruct Greene's travels through Spain and Portugal. The author argues that these regions served as more than mere backdrops, acting instead as catalysts for the theological and political tensions that define Greene's major works.

Scholars of 20th-century literature note that this text provides a specialized perspective on Greene's creative process. It is frequently cited as a useful resource for those interested in the geographical influences on modern British fiction.
