Methodically researched and cogently argued by three New York Times reporters (one of whom received an anthrax-tainted letter recently), this survey of the modern history of biological weapons is a worthy, albeit frightening, exercise in investigative journalism. The book details the evolution of biowarfare (beginning about 60 years ago) from the U.S. to Iraq and the Soviet Union, vividly portraying these weapons in all their power and nightmarish possibilities. Guyer brings a dry but authoritative and appropriate journalistic tone to his reading. His is the steady, baritone voice of a network news anchor, and it works well conveying weighty information about major international events and politics. Thankfully, despite the topic's sensationalist possibilities, this production stays true to the sober, reasoned style of the text and steers clear of punctuating the reading with ominous or melodramatic musical flourishes. There's plenty in the facts themselves to convey unease, and while it might not be the lightest listening, there is no doubt that this is a high-quality production of a balanced and informative look at a growing global threat. Based on the S&S hardcover. (Nov.)
