A Darkness More Than Night is the tenth novel by American crime author Michael Connelly; it is the seventh featuring the Los Angeles detective Hieronymus "Harry" Bosch, and the second featuring FBI profiler Terry McCaleb, with reporter Jack McEvoy (The Poet) also making an appearance in a supporting role.
Nevertheless, sheriff's deputy Jaye Winston asks McCaleb for help in investigating the ritualistic murder of a suspect named Edward Gunn.
This prompts Rudy Tafero, Gunn's actual killer and an ex-cop who handled security for Storey, to target McCaleb.
Less significantly, David Storey's name is changed to Andrew Holland, while prosecutor Janis Langweiser becomes Deputy District Attorney Anita Benitez, whom Bosch is dating.
Edgar realizes the truth about Bosch having witnessed Gunn's murder after Bosch mentions during his interrogation of Rudy the specific model of car that the Taferos drove to the scene of the murder before Rudy mentioned it, and it is not visible within the spy-camera's viewing area.
