Well the best way and only way is to save constantly so when you do get caught, you can just load your game from there and do it again. If you did beat the game and didn't get the achievement, then you were caught in the past levels. Selecting a level wouldn't count because it's basically skipping the game as if you haven't played the past levels. So if that's the case, then you must clear the whole game again.
