On PC here…
I received the quest “The Goid Thief”, but got sidetracked with the main quest and just ended up paying off the Miller and the apothecary. Then decided to go back and complete the Good Thief Quest. Got the executioner to leave and talk to the Miller st which point I successfully robbed his house but didn’t find the ring. So I figured the executioner had the ring on him so as he was on his way back to his house I knocked him out and mugged him, but he didn’t have the ring on him. I have been back to his house 3 times now and mugged him another three times, still no ring. Am I just outa luck? Is the quest broken?
