Author unknown

In Author Unknown, Don Foster reveals a startling fact: since no two people use language in precisely the same way, our identities are encoded in our own language, a kind of literary DNA. Combining traditional scholarship with modern technology, Foster has discovered how to unlock that code and, in the process, has invented an entire field of investigation -- literary forensics -- by which it becomes possible to catch anonymous authors as they betray their identities with their own words. - Jacket flap.
