I just finished “Brass Verdict” by Michael Connelly, and there was a jaw-dropper (at least for me) at the end of the book. Now I might have to go back and re-read some of the earlier Harry Bosch books to see if he dropped any hints (I won’t spoil it for you).
This book brings Harry Bosch (detective) and Mickey Haller (lawyer) together to solve a mystery involving the death of an associate of Mickey’s. Barnes & Noble describes the book as “Harry Bosch #14 and Mickey Haller #2.”
I’ve read all the Michael Connelly books in chronological order ‘cos he weaves main and support characters in and out of his books, which makes them very fun to read since they’re somewhat intertwined.
