What is the author's style in The Black Echo by Michael Connelly?

The Black Echo follows LAPD Detective Harry Bosch from the time he discovers that a dead body is that of a colleague in Vietnam through the surrender of his partner and lover, FBI Special Agent Eleanor Wish. The lion's share of the novel is devoted to following clues. Bosch is under suspension and visiting Mexico when a major bank robbery occurs. This provides an opportunity for Wish to fill him in on particulars. She goes into meticulous detail about the robbers' planning and execution, seeming to admire their handiwork. Only at the end of the novel does she reveal that she pulled the strings while letting her boss, whom she wants above all to bring down, to think he is in charge. The anonymous third person omniscient narrator seems closer to Bosch's perspective than to Wish's and does not betray the truth until Bosch stumbles over it. Several times, the value of hindsight in police work is mentioned.

There are numerous summaries - and some psychological flashbacks - to Bosch's institutional upbringing and service in Vietnam. How he attains the popular fame that saves his neck when he is accused of killing an unarmed suspect is brought out piecemeal in conversation between himself and Wish, who has read his files and psychological evaluations. She shares with him a sanitized version of her life's story, stopping short of admitting any guilt. Only when Bosch puts the last puzzle pieces into place and confronts Wish does she gratefully get the weight of years off her chest, confessing and justifying her actions, while specifying that none of the innocent bodies are her fault, and she has not lied to Bosch. She wants only to get back at those who used and murdered her brother 15 years earlier.
