Emerald City Confidential is a 2009 computer adventure game conceived by Dave Gilbert, developed by Wadjet Eye Games and published through PlayFirst. It follows the protagonist Petra, Emerald City's only private eye, as she is approached by a strange woman named Dee Gale. Dee's fiancé is missing, and she is willing to pay Petra above the going rate in order to find him. Lacking any other prospects, Petra agrees. What starts off as a simple missing person case soon takes Petra deep into the seedy underbelly of the Emerald City's criminal underground and beyond. She encounters many characters from the Oz canon and some new characters, learns several magic spells, and uncovers the answer to a dark secret that has haunted Petra all her life.
