Mr. Lee has taken this obscure but, currently vital topic of concern to a level of understanding based on the little information actually available on the smuggling of nuclear materials. His text is careful to explain that there is a lot of ambiguity and concern for facts in his statements. It is very clear that the actual materials successfully smuggled is not and will probably never be known. His lists and charts are a big help in understanding why people try to smuggle these terrifying products. His information is carefully researched and documented with a large array of footnotes in a block section at the end of the book. Although it is a small book, it represents a very large amount of available data condensed into one place. The information about the involvement of government officials and the manipulations of the Russian Mafia show how convoluted this racket can become and why they are getting away with it. In short, he has tackled an obscure subject in the same way he approached the Andean Cocaine trade. The book is an easy and alarming read.
