Ghost Gone Wild is the fourth installment of the Bailey Ruth Ghost series by Carolyn Hart. Bailey Ruth is a ghost that is allowed to return to earth as an emissary from Heaven’s Department of Good Intentions. Her latest mission seems to be off the grid, and right from the start she suspects that something is different, as the Rescue Express seems uncertain about her destination. Luckily arrives in her old town just in time to rescue wealthy Nick Magruder from being shot. After she saves the Nick, Bailey finds out she is stuck on earth because it was not a true mission from the Department of Good Intentions. Using her sleuthing skills and sweet talk, Bailey goes undercover in different disguises to find out who would have the motive to harm Nick, and why this victim is now a suspect for murder.
