Query: Interesting but ultimately fails

I found this book to be engrossing, and at times extremely entertaining, but in the end, it fails due to its shoddy ending. It is a shame, as until that point, the book is extremely well written, with a riveting story set amidst a highly detailed and fascinating backdrop of Victorian England that makes one feel as if one is almost reading a historic novel. Then comes the ending, which leaves the reader completely dissatisfied, wondering why one has wasted so much time on such a long novel.Had Faber given as much effort to the final part of the book as he did to the rest, "The Crimson Petal and the White" would merit four or five stars. As it is, it gets the rating I have given it.
