In Hostile Takeover and Changed Man, Mike Black returned to his past to tell you more of the story that you only thought you knew. That story continues in 12 Days in December.
December is Black and Bobby's birthday month, they've been celebrating with Wanda since Thanksgiving and the celebration won't end until well after New Year's. It was also the first December following the tragic death of their friend Vickie Payne and each of the three deals with it in their own way.
In spite of that, they were hunting for Gun because he tried to kill them, looking for O, so Black could kill him and Simon Parrish owed them a hundred thousand dollars, so they were hunting for him too.
With an expanding business to run, the police coming for him from all sides, and enemies that need to be dealt with, the not so changed man deals with it all the Vicious Black way.
