"One of the two novels which Henry James left unfinished at his death ... designed to consist of ten books. Three only of these were written, with one chapter of the fourth, and except for the correction of a few obvious slips the fragment is here printed in full and without alteration ... The pages of preliminary notes, also here printed in full, were not of course intended for publication."--Preface (signed: Percy Lubbock)

"The Ivory Tower" by Henry James is an unfinished novel posthumously published in 1917. Set in Gilded Age Newport, it explores the corrupting influence of enormous wealth left behind by two dying millionaires and former business partners. When Graham Fielder inherits a vast fortune from his uncle, he must navigate a world of unscrupulous fortune-seekers and tainted money. James intended this brooding work as a fierce attack on the plutocrats of his era, examining how great possessions carry darkness at their roots. (This is an automatically generated summary.)
