Sorry I am sick to death of Katherine. She seems to be a cross between Mother Theresa and Superman. Always there when needed (OK she could have taken the info in and met the guilty copper, but then she's the one to get the statement from the wife's lover, they meet GC as he is leaving, she jumps into a car and pursues) Always ready to talk to people, woman who has targeted her grandson, woman who shot her own son. And shouldn't she be on a charge for disobeying orders and chasing man to his death? The rest of the coppers of course just stood and watched. I think there wasn't enough in the budget for a fire so the ending had to be less catastrophic.
