Two Kinds of Truth by Michael Connelly

Harry Bosch's past as a LAPD detective comes back to haunt him when the department's Conviction Integrity Unit lets him know a killer named Preston Borders that Bosch put on death row is probably going to be released because DNA evidence has been found exonerating Borders.  Bosch knows he's guilty, but wonders how is he going to prove it. Bosch also worries about how this case will affect his reputation as a investigator.  He might also find himself as the plaintiff in a lawsuit if Borders is let out. To make Bosch's life even busier, he is working for the San Fernando police department on the case of a double murder at a pharmacy, even though he's "retired." Two Kinds of Truth is another unputdownable read from Connelly. The appearance of Bosch's half brother, Mickey Haller, as part of the storyline adds some needed lightness to the story. Really not to be missed...
