La Ingratitud de Sarmiento Juan Carlos Casas 256 pages - IN SPANISH Based on "Travels through Europe, Africa and North America -1845/1847 " by the Argentine Domingo Faustino Sarmiento, where he carefully details his trip but fails to recall the name of the American lady who helped him with money in Pennsylvania. Why Sarmiento shows himself as ungrateful to his benefactress? Could he be chivalrously concealing the name of a lady whose reputation he might harm due to a secret love affair? Juan Carlos Casas fills-in the gap based on the tenuous traces a careful Sarmiento fails to conceal completely, while keeping the rhythm and attractiveness of the issues that concerned the traveller at the time.
