The San Tome silver mine, with its immeasurable riches, proves an irresistible lure to the men of ambition who rule the South American Republic of Costaguana. Drawn into their corrupt circle is the owner of the mine Charles Gould, an idealistic Englishman whose principles are slowly eroded away by his obsessive desire to hold on to the mine at any cost. When revolution breaks out, Gould calls upon the loyal and fearless Nostromo to hide away the latest consignment of silver. But will Nostromo, resentful that his worth is unrecognised by his superiors, be able to resist the promise of future prosperity that the treasure offers? Conrad's unsparing account of the nature of corruption and its power to destroy or defeat good is considered by many to be his masterpiece.
