The difference here is that the perspective is not of the aging literary lion---which tends to create sympathy for him. This beautifully written novella tells the story from the point of view of his daughter. The dutiful daughter that one may say lacked the sense to move on and away from the selfish life devouring presence of her famous father. We see him in all his selfishness, his aggression used to mask his insecurities, and his overwhelming and all encompassing ego.
Good books sometimes not only make you think about what you have read, but make you re-evaluate other books that you have read. Patricide is just such a book. Told with the chilling understatement of a master.
