Quentin Falk, Travels in Greeneland: The Cinema of Graham Greene (Quartet, 1983) An excellent overview covering all films made of or associated with Greene's novels and stories from the '30s to '80s.

Graham Greene, A Sort of Life (Bodley Head, 1969); Ways of Escape (Bodley Head, 1980). These two autobiographies are immensely interesting insights into the mind of the writer, especially one as complex and well-travelled as Greene. The first deals with the first twenty-seven years of the author's life; the second, more anecdotal in its construction, takes one through the various novels and locations which make up and contribute to the bulk of Greene's work.
