Query: Bosch at his best

Michael Connelly consistently delivers exciting hard-boiled police procedurals with Harry Bosch in control. In Black Ice Bosch is cut out of an investigation of an apparent suicide of narcotics officer Calexico Moore by the bigwigs of the department. They want to do what is pc and Bosch is definitely not that. At the same time Bosch's supervisor Pound feels compelled to increase the percentages of his homicides solved so Bosch is elected to solve some cases of an out on stress leave detective, Porter. Harry realizes that Porter's case, his own and Moore's "suicide" are all tied together. As usual Bosch cuts corners and goes out on his own to make the pieces fit.An excellent read for any fan of mystery and suspense. Connelly is always exciting and hard to put down. I am ready for a new one. For anyone unfamiliar with Connelly and Harry Bosch, read them in order and not spread out over years as I have done.
