Keith Wolverton was a Captain with the Cascade County (Montana) Sheriff's Department from the 1960s until his retirement in the 1980s. The events in Mystery Stalks the Prairie represent countless hours of research and investigation on the part of Captain Wolverton and his fellow officers. He died in 2019.

The new introduction is written by Dr. Joan Bird, a longtime advocate of the existence of UFOs and related phenomena and the author of Montana UFOs and Extraterrestrials (Riverbend Publishing, 2012).

The interview transcribed in the new edition with Wolverton and fellow county sheriff Pete Howard was conducted by Dr. Richard O'Connor, an anesthesiologist in Helena, Montana, who is active in UFO research. He started the Jesse A. Marcel Library for UFO research and discussions in Helena. The library was named after the Army major who investigated the 1947 Roswell, New Mexico, UFO crash. For many years Dr. O'Connor worked with Marcel's son, also a Helena doctor, and often had heard the son tell of his father showing him strange pieces of debris from the UFO crash site.
