Remember Richard Clarke, the guy from the National Security Council who came out with a book that accused the Bush administration of negligence that resulted in 9-11? He is now into fiction writing! Check out his new book.
Sounds like he is putting his retirement to good use. It was not very long back (last year?) that his previous book was released and generated a lot of press (given its controversial nature). A second book in such a short time is quite an accomplishment (or he has a team of full time ghost writers!) .
