This is a book that gives us a detailed look into the lives of three rather dissipated characters: The elder Saccard, his second wife, Renee, and Maxime, a son borne of his first marriage. All three are competely unconscionable people but, due to the genius of Zola, there is, somehow, pathos in their positions. Saccard is a man who thinks of nothing but money (clearly seen in his actions duirng the death of his first wife) though the reader is made to feel sympathy for him when his empire begins to crumble and his business partners take advantage of the situation. Maxime is a cad of the first order but little else could really have been expected of a man who from his youth was 'Renee's plaything'. Renee is a character simply searching for affection amid the falseness of Parisian high society.
La Curée is an excellent example of the realist/naturalist style, however, this is not for everyone and some may find certain section pertaining to social convenitons of the time rather dull. The beauty of the writing is, however, for all to enjoy.
P.S. Fred "the shred" Goodwin and his brethren should have checked out the bits about reckless speculation - most informative
