Lost Light by Michael Connelly

Harry Bosch has finally quit the LAPD.  When he left, he took a file with him - the case of a young woman murdered four years earlier.  The crime was linked to a $2 million robbery on a movie set, and the LAPD think the money was used by terrorists.  Now, with time on his hands, Harry looks at the old file again.  Something about the victim affected him deeply and the case has haunted him ever since.  But when he decides to re-investigate, he falls foul of both his old colleagues and the FBI.  And then someone from Bosch's past turns his world upside down.

Soft cover, good condition.
