Barry Unsworth's Losing Nelson is a novel of obsession, the story of a man unable to see himself separately from the hero he mistakenly idolizes Admiral Lord Nelson. Charles Cleasby is, in fact, a Nelson biographer run amok. He is convinced that NelsonBritain's greatest admiral, who finally defeated Napoleon, and lost his own life, in the Battle of Trafalgaris the perfect hero, but in his research he has come upon an incident of horrifying brutality in Nelson's military career that simply stumps all attempts at glorification.
