Demille (born 1943) wrote this John Corey thriller at the age of 67, at the height of his fame, or maybe quite some time after it.
The background to the story is the 9/11 attack on the World Trade Center and its aftermath of almost paranoid US counter attacks. In one of those in Libya Asad Khalil lost his family and has come to the US to take his revenge on the Americans and, specially on former NYPD homicide detective John Corey.
Demille tells his gripping story with irony and sometimes blatant sarcasm, showing his countrymen how their lack of consequences is putting them at risk as far as terrorism goes. And like in a mirror Khalil´s strong Muslim beliefs make him despise their decadent ways of life.
All very well, but Demille is just overdoning it. Another attack on Ground Zero is imminent and the final shootout between Khalil and Corey.
