A hagliographyhagiography is a book or long article which praises and exaggerates the characteristics of the subject and lauds his/her accomplishments. Historically it is about a saint.
I am looking for an antonym to describe Seymour Hersh's book, "The Dark Side of of Camelot", about JFK. This book intertwined truths with rumors, calumnies, unverified quotes, etc.
As far as I am concerned, Hersh's book is no better nor no worse than a hagiography.
So, how can his book be described in one word?
