Maugham's success, in fact, lies a good deal less in what he positively does than in what he discreetly leaves undone. He gets the colors of life into his Charles Strickland, not by playing a powerful beam of light upon him, but by leaving him a bit out of focus--by constantly insisting, in the midst of every discussion of him, upon his pervasive mystery--in brief, by craftily making him appear, not as a commonplace, simple and completely understandable man, but as the half comprehended enigma that every genuine man of genius seems to all of us when we meet him in real life.
