There is a book amusingly titled "The Real Napoleon--the Untold Story" that, among other head-scratching blunders, fallacies, and bloopers, devotes its very long Appendix to a diatribe in fawning favor of the arsenic theory publicized by You-Know-Who and an amazingly heated screed against every current historian who disputes the arsenic theory.
Worth a quick look, if only for hilarity on an otherwise boring day.
