Ellroy reveals behind the American decor of the period 1958 until the assassination of JFK in 1963. Through some iconic characters, it addresses the critical issues of the time: anticommunist obsession grip of mafia, corruption on all floors, plot to the JFK assassination. In this backwater putrid, you see more or less rotten cops and ultraviolents, crooked politicians, racketeers and cynical of pundits crime. In the background a neurotic society, racist, homophobic, creepy. The myth of the American dream embodied in a JFK ultrabright smile shatters. Everything is against-handling and manipulation. The writing is clear and concise, no frills. Each sentence is information. It is a dense story, streaky secret reports which increase the pressure and violence scenes ever more unsustainable. Very soon, the plot explodes and becomes a complex and dense imbroglio well aware of the extreme intertwining of political power and occult forces (which, admittedly, is difficult to see). The fictional works full-power tube; the story quickly took off the documentary stage to stage an obscure and psychological America, but the classic detective story lovers will be rerouted.
