Query: more of serafini's hard-hitting journalism

In this work Serafini maintains his reputation for tough-minded journalism, pretty much making hash of Pauling's admittedly sometimes over-hyped reputation. The problem I find with it however is that it is a little too soft on Paulings science; after all the man did do some revolutionary work. Also, while generally well-written it is marred occasionally by some awkward phrasing and repetition. But overall it is an excellent work, comparable to Tom Hager's biography of Pauling.
