The Drop by Michael Connelly
Harry Bosch is working in the Open-Unsolved (cold case) unit. He and his new partner Chu get a case from 1989 of rape and murder. The DNA matches a convicted rapist. However, there is a big wrinkle. This means the rapist committed the crime when he was eight years old. How could this be?
At the same time they are requested to resolve a suicide/murder of a man falling from the balcony of a hotel. They have been asked for by the man's father, Councillor Irving. Yes, Irving as in Bosch's archenemy.
Both cases are police procedural type and Bosch and Chu follow the leads and clues amidst the twists and turns the reader loves.
Another great mystery times 2 from Connelly. Bosch is tiptoeing his way through fatherhood with a delightful daughter who wants to be just like Dad, a cop. On the romance front Bosch is trying but for me this fell real short and I say move on. I loved Bosch's interaction and tutoring of Chu. I hope this partner lasts a long time. Can't say I was all too happy with the resolution of one of the cases but sometimes things are not all rosy inside
Bosch is set to retire in 2 years. OH NO!
