The Treasure of the Sierra Madre - B. Traven, Penguin Books Ltd

'Gold is a very devilish sort of a thing, believe me, boys'Deep in the wild heart of Mexico’s Sierra Madre mountains lies treasure beyond reckoning, just waiting to be found by those who know where to look. Or so believe three Americans – Dobbs, Curtin and Howard – down on their luck and desperate for a way out. Teaming up on a perilous quest to hunt for gold, they soon find their fragile alliance tested, both by a band of local outlaws, and by their own greed. First published in 1927 and made into a classic film by John Huston, The Treasure of the Sierra Madre is a savagely ironic, anarchic cult novel about the price of ambition and the limits of endurance.
