A bit more info than we have previously had.
We knew it was Marcone, as the ultimate antagonist but the two Lawyers? Previously Harry relied upon Father Forthill who is also a qualified lawyer and veritable saint. Is he the lawyer who might be more than he seems? Or a new character? The one who is definitely more than he seems might be an entirely new character. We have seen Mab as a lawyer and White Court Lawyers, I am not entirely sure Harry would go for either. Demi-god? the cover makes me think of Justicia, The junior Roman Goddess of Justice, one of the four virtues is that the Lawyer who definitely more than they seem? Forthill might br Uriels man in the fight, If so Justicia might be Hades? The Greco Roman Etruscan gods are so entwined.
