Another great entry in the Harry Bosch mystery series. Several times in this book, Clint Eastwood and "the movie" were mentioned. I googled it and found that a previous Michael COnnelly book, BLOOD WORK, was the basis for a 2002 movie starring Eastwood as Terry McCaleb. In THE NARROWS, Bosch is investigating McCaleb's death. Very interesting and complex plot, but all the loose ends were tied up satisfactorily by the end.
