Twenty-something, John Abernathy is disillusioned. His job as a private investigator is unfulfilling, and he can’t find work in his chosen field, Enigmatology, the study and design of puzzles. He is about to quit when the National Enquirer calls. A woman in Las Vegas, New Mexico sent them a photo of someone who’s supposed to have died 35 years ago—Elvis Aaron Presley. And they need John to investigate it.
When the Elvis impersonator, Al Leadbelly, is murdered, John investigates, finding Air Force colonel, Alvin Hollister—convinced Leadbelly has information regarding Elvis's death—at the crime scene conducting his own investigation. John discovers great-great-great grandfather's journal—unearthing a conspiracy entwining Elvis, shape-shifting aliens, and Mary Todd Lincoln. When John finds Leadbelly, alive and wearing a sequined jumpsuit, John must help him escape before Colonel Hollister finds him, and discover if Leadbelly is really Elvis, an obsessed fan, or something more.
