I don't really know if this is a forgotten book(s)or not, but I thought I'd mention it. I believe it was originally published in one volume, but it was divided into three for paperback publication. If you can read the blurbs, you can see that each book is called "The Definitive Book of American Crime." That's pretty much accurate, at least up to the time the book was published. Volume three ends with Charles Manson, so there are plenty of bloodletters and badmen to be written about in a future volume. Or maybe there's already another volume that I don't know about.
Anyway, the books are arranged alphabetically, and if Nash left out any criminal in American history, I don't know who it is. These books are, as another blub says, "Packed with photographs and illustrations," along with a brief summary of the career of whatever criminal you might choose to read about. Wonderful browsing material, and maybe even an inspiration if you're looking for great characters. Highly recommended.
