Melton and Wallace describe virtually every conceivable type of spy activity--all of which have played out here. The book is richly illustrated with well over 300 photos of sites, people, and spy gadgets. Also included are maps and lists of spy sites by neighborhood, city, or county so that readers can undertake their own spy-site tours.
