The Human Factor is Greene’s most extensive attempt to incorporate into fiction what he had learned of espionage when recruited by MI6 during World War II . . . What it offers is a veteran excursion into Greene’s imaginative world . . . Sometimes seen as a brooding prober into the dark recesses of the soul where sins and scruples alike fester, he is equally at home in sending a narrative careering along at break-neck pace . . . Raising the demarcation line between ‘serious’ fiction and fast-plotted entertainment, Greene ensures that components of both jostle energizingly together in his pages.” –from the Introduction by Peter Kemp
