Michael Connelly brings back both of his series characters, now retired detective Harry Bosch and criminal defense attorney Mickey Haller, in his latest novel, "The Crossing."

Bosch is restless since he retired from the Los Angeles Police Department. His world has turned upside-down, and he misses all the perks associated with his former profession. And he's bored.

Enter Haller, who asks Bosch to track down evidence to prove his latest client's innocence. The man's DNA was left at the scene in the death of a sheriff's wife. Bosch immediately assumes guilt, but agrees to read the case documentation.

The more Bosch reads, the more he begins to ask questions. If he decides to investigate, it will put him on the defense side of the aisle, the opposite of how he's spent his life enforcing the law and catching criminals.

Haller knows his client is innocent, and he also knows how to play to Bosch's sense of morality and justice. What they both don't realize is that by pushing for the truth, they become targets.

The case relies on trying to determine where the victim and the killer crossed paths. Bosch has his own crossing when he decides to work for Haller. Haller's crossing is convincing Bosch to trust him, even when he's keeping his own set of secrets.

Connelly continues to write quality crime fiction, and "The Crossing" is another great character study mixed with a truly baffling puzzle.
