[The Lafarge affair: a judgment in which toxicology didn't win fame!].

The famous Lafarge affair which took place in Tulle (Corrèze, France) in 1840, has never ceased to interest the general public because some doubts have remained even after the pronunciation of the judgment. Another hypothesis than arsenicum poisoning has been formulated in 1980 by Professor P. Lepine who believes in a paratyphoid fever occuring after food poisoning. This assumption and the discovery of exceptional family documents in 2004 by Edouard de Lamaze, a distant cousin of Emma Pontier, the confidante of Marie Lafarge, sheds a new light on this mysterious affair.
