There were traitors in the council and Harry knows all this from personal experience, he and his brother once went all through this in White Night . Now another friend is in same kind of situation and for help he had no one to go to except Harry who has been showing readiness to take such cases. Warden Morgan gets the punishment in response to his crime of treason that means only one thing i.e he is going down.
The Council will show no mercy in this regard and though the man claims that he is innocent he has nothing to say or provide in his defense. Being on the run for a while he reaches Harry who is bound to help him but for this he cannot just come out in the open and support him in front of the council. Harry very cleverly works within his limits so that his support is not visible to anyone because he can unveil the culprit by keeping himself in the council and of course making less number of enemies as possible.
With every step taken and every attempt made the strangle hold of the Council is approaching near the neck. Jim Butcher uses the same style in the story progress as was used in Small Favor. But the narrator James Marsters does not puts in the same style because it is not personal this time rather it is professional.
There has been another noteworthy change in the series since the previous three parts, not a lot of fairy tale creatures are involved the stories only discuss wizards and the wizard world.
