Adult/High School-Harry Bosch, the worn, pragmatic Los Angeles police detective, protagonist of a number of Connelly's earlier books, is joined by Terry McCaleb, former FBI crime-scene profiler, introduced in Blood Work (Little, Brown, 1998). Harry is immersed in testifying at the murder trial of a Hollywood film director, Jack Storey. When McCaleb, retired and living a quiet life with a new wife and two young children, is asked by a former colleague to look at the investigation materials of a recent gruesome homicide, he realizes just how much he misses his vocation. Terry alone has noticed some clues from the crime-scene video that point toward the influence of Renaissance painter Hieronymus Bosch. Despite pleas from his wife, Terry is drawn into the investigation and finds, to his dismay, that pointers lead straight to acquaintance Harry Bosch, whose real name is Hieronymus. Certain details in Harry's life fit in well with the profile Terry is developing of a ritualistic killer. The clues stemming from Bosch's paintings may lead readers straight to the Internet to view some of Bosch's well-known works to see the clues for themselves. The plot is intricate, and the twists and turns keep coming...
