A year after the victory at Talavera, Wellington's army, outnumbered and bankrupt, is on the verge of collapse. Its only hope lies in a cache of gold hidden in the Portuguese mountains, and the only man capable of stealing it is Captain Richard. He embarks on a secret mission that pits him against the French army El Católico, the fanatical Spanish guerrilla leader and El Católico's lover, the beautiful but deadly Teresa. A series of battles lead him through Portugal to the fortress of Almeida, where he is trapped. But Sharpe is determined to succeed -- even if it means turning against his own side.
