The Drop by Michael Connelly

Harry Bosch and partner are called to a death scene that is loaded with political implications. The son of councilman and nemesis Irvin Irving is found dead after an apparent fall from the seventh floor of a hotel. The question is, did he jump or was he helped? Irving wants Bosch to find out what happened no matter what the outcome. But does he really mean it? Meanwhile, Bosch and partner have just gotten a lead on an old cold case that he wants to clear. The pressure is on, making Harry re-think his decision to continue working on cold cases. Will he retire when these cases are completed? His teen-aged daughter at home is making him consider his future. Connelly writes an action packed, thought-provoking mystery that this reader hated to have end. A great read.
