Will lightning strike twice?

AMC is so happy with the success of their adaptation of Robert Kirkman's comic book series The Walking Dead that they've picked up his latest project for development, too. THR describes Kirkman's Thief of Thieves as the story of "a master thief with a dual identity who, while struggling to quit the business, opts to steal only what has already been stolen". Not quite sure what that "dual identity" phrase means, but the more comic book adaptations the merrier, as far as I'm concerned.
