This is a thoroughly researched, factual, non-fiction book. There is a map in the book where people disappeared, and visitors to the Great Smoky Mountains can visit the sites.

Three people, Pauline Melton, Trenny Gibson, and Dennis Martin, vanished without a trace during daylight, from different locations, on different dates, and surrounded by other people. These disappearances remain unsolved to this day. Not one clue has ever surfaced to offer a possible explanation.

There are two puzzlers narrated in this book. An unidentified boy was found frozen to death in 1915, and buried by kind strangers. His identity was a mystery for 60 years. Abe Ramsey, age 3, wandered away from his on March 11, 1919. For many years the story was told that he was never found; there is evidence that this may not be true.

Two notorious felons, William Bradford Bishop, Jr., and Eric Robert Rudolph, tried to escape in the Great Smoky Mountains. Bishop was successful, and no trace of him has ever been found. Rudolph hid successfully for several years, but was captured in 2003.
