Quite good history of the search for James Earl Ray. The author claims he used the techniques of a novelist without his license, as described by Shelby Foote. In a discussion of the FBI's decision to concentrate on reviewing fingerprints from convicts instead of their larger file, the author says that this reduced their work by "several orders of magnitude", but the reduction was from 53,000 to 1,900, clearly a reduction of a single order of magnitude.
