The Eustace Diamonds - Anthony Trollope, Stephen Gill, John Sutherland

A dense read at times but I loved all the different characters. Lizzie Eustace is one of the nastiest, most scheming "stab-you-in-the-back-while-wearing-a-smile" women I have read in years! I guessed the ending pretty early on but because the characters were so well written, it kept me reading. When you think about it, it is amazing that such a lengthy plot was written solely around the theft/disappearance of a diamond necklace.  As the story unwinds, the plot expands to reveal itself as a study in human character as well.
