This season has been an improvement on the first - which was pretty damn good to start with. This episode has Bosch getting in deep with Chief Irvin in investigating the death of Irvin's son. When Bosch finds info on Dash which implicates him in Allen's murder, he sees a way to tie the two cases together and put Nash away. Not everything goes as planned when both sides find that Allen's widow is about to get away with the money, forces gather at the bank and a shootout ensues. Not everyone will survive. The depth of story writing is superb and the acting is equal to the task. One of the best episodes of TV on any network I have seen this year.
