Story : ""Mr. Lucky"" is Enzo Fiorelli, a charming, charismatic and successful con man. Several years ago he defrauded most of Mt. Thomas' Italian community for everything they had, destroying their lives, ruining businesses and leaving a trail of grief and outrage. Enzo Fiorelli paid for his exploits with a long stretch in jail. Released, he inexplicably walked out of his witness protection program, blowing his cover forever, and returned to Mt. Thomas. The Heelers struggle to keep a lid on the community's righteous resentment for the man who caused so many of them so much pain. At first it's only hate mail, and then it's a brick through the windscreen of Enzo's expensive car… but then it's a bullet through one of his tyres. Is it the community? Is it Enzo himself, trying to get the Heelers to give him full-time protection? And why has he returned to Mt. Thomas, where there is so much hatred directed towards him.
