Query: Too bitter

After reading this book, I couldn't help but wish Theroux had let some years (or even decades) pass before he wrote about Naipaul. Perhaps, with the passage of time, the bitterness that so evidently taints the latter parts of the book would have been damped, and Theroux would have been able to treat his subject with more clear-sightedness and fairness. Perhaps he would have been able to write the book he claims to have written -- an examination of friendship and of the relationship between two writers. But as it is, Theroux's sight seems clouded by an inchoate passion, and much of his book reads like the self-justifying ramblings of a jilted lover: no careful examination, no insight, no growing awareness -- only a laundry list of Naipaul's idiosyncrasies and character flaws. I think only people who are really interested in Naipaul and/or Theroux will want to read this book.
