Mickey practically invites us to not like him. He's a criminal defense attorney, skilled in finding loopholes, technicalities, and cop-sloppiness, all in order to minimize the legal damage to his (almost invariably) guilty clients. He skates on the edge of lawyer ethics and financial ruin. His office is a Lincoln Town Car, because he's continually on the move between various LA County jails and courthouses. Also on his mind are two ex-wives and a young daughter he doesn't seem to be able to find time for.
Here's the thing about Connelly: although it would be easy for the reader to perceive Mickey as a money-grubbing shyster, Connelly manages to make him sympathetic and even likeable, right from page one. It's magic!
Things kick off when (seemingly) fortune smiles on him: his favorite bail bondsman hooks him up with a very rich client, who's been charged with a brutal assault against a woman. Mickey's subsequent investigation is centered around delivering a Not Guilty verdict, but it rapidly becomes obvious that there is more going on than meets the eye.
This was made into a pretty good movie last year starring Matthew McConaughey as Mickey. I liked it quite a bit, but seeing the movie first did not degrade my enjoyment of the book.
