From the professor who invented literary forensics--and fingered Joe Klein as the author of Primary Colors --comes the inside story of how he solves his most challenging cases Don Foster is the world's first literary detective. Realizing that everyone's use of language is as distinctive as his or her DNA, Foster developed a revolutionary methodology for identifying the writer behind almost any anonymous document.

A few weeks later, Foster solved the mystery that had obsessed America for months when he identified Joe Klein as the author of Primary Colors . Foster also took on a case involving the elusive Thomas Pynchon. And his contributions to the Unabomber and JonBenet Ramsey cases have led the FBI and several police forces to hire him to train their organizations. Introducing a fascinating new field of forensics, Author Unknown will appeal to mystery fans-and to everyone interested in words and the writer's craft.
