Season 4 begins again with a variety of events where Brenda investigates the murder of a woman. There may be a stunning discovery about the wild fires that have been found and complicated by Bill Carrick's appearance. It seems that Bill is either the probable suspect or the best person who will have to find the killer in that period.
It does a fantastic job of reestablishing a real world environment while still presenting an investigation with enough twists and turns to keep things interesting.
