After a prologue by the author himself, in which he tells what place he occupies in his work and how important all his stories are, this volume brings together the four short-story books that were published by Graham Greene, along with three other unpublished stories in Spain. In these stories it can be appreciated to what extent Greene was a ductile author, capable of giving small masterpieces of humorous literature, of condensing in a few pages the exposition and development of deep-seated moral problems, of building unforgettable characters showing them in just two or three scenes or to articulate various narrative mechanisms to pose to the reader enigmas that will test both his insight and his ingenuity.
