Robert Steele's critically acclaimed April 2000 book on open source intelligence.

Reviews:
Alvin & Heidi Toffler: "Few have thought as deeply or imaginatively about such questions as a super-smart, forty-one-year-old former Marine and intelligence officer named Robert D. Steele. Steele's vision will thrill many--and send a quiver down the spines of others."
The Honorable Richard Kerr, Former Deputy Director of Central Intelligence: "Robert Steele storms into the core of intelligence issues without fear. The scope of his work is impressive and whether you agree with him or not, you cannot ignore what he says. The book is an important addition to the literature on intelligence."
