The story opens with all-out action when Vincent Smiley, a cop-hater, decides to wreak his vengeance on the various law enforcement agencies by shooting a sheriff’s deputy who tried to serve him with a warrant. The agency actually responsible for the origin of the warrant was the ATF. What the ATF failed to warn the sheriff’s department about was that Smiley was suspected of hoarding a huge stockpile of weapons and explosives in his house.

Sheriff’s deputies, tactical response teams and the ATF descend on Smiley’s house where he is firing indiscriminately from every window, daring the police to attack him. They finally do attack with the result seeing the house with Smiley inside, burning to the ground.

In the aftermath of the incident blame is passed between the elite forces of the sheriff’s department and the ATF over the handling of the incident with neither group convinced that the other is telling the truth as to their knowledge about how dangerous Smiley was. What follows would be the police force’s worst nightmare when the bad feeling between the two agencies escalates to the brink of outright war when first, a member of the ATF’s SRT (Situation Response Team) is shot by a sniper then a member of the sheriff’s department’s SEB (Special Enforcement Bureau) is shot and killed in exactly the same way.

Shane Scully, as a homicide detective with the LAPD and consequently independent of the two agencies involved, is asked to investigate the original shooting and subsequent fire. The fact is that he is asked to investigate by his boss, who also happens to be his wife, Alexa because she can trust him over all other detectives to get the job done.

Of course, how can he refuse, but what he is not prepared for is the assignation of a partner from the sheriff’s department, an IAD officer no less, named Jo Brickhouse. This partnership quickly becomes the classic hate-hate relationship that is to gradually thaw out to respect, admiration and trust. Although it’s been done many times before, I thought it was a particularly strong part of the book and helps define Scully both as a police officer and as a family man.

The pressure that Scully comes under in this case is like no other he has experienced before. Firstly, Alexa continually questions his investigation techniques and second guesses him because results don’t come quickly enough for her. Secondly, Brickhouse refuses to concede anything to him, particularly not that he might be carrying out a thorough investigation. All of this added pressure creates an atmosphere of desperation that had me hoping just a little harder than usual that Scully would make the right decisions. (Silly me).

I must admit, I saw where this story was going from pretty early on and so, by the time Scully had uncovered the clues and made the earth-shattering revelation, my reaction was merely one of satisfaction that my own sleuthing was vindicated. However, I will pardon Scully for not getting there as quickly as I did, considering the personal pressure he was working under at the time.

This is a highly charged thriller combining an interesting mystery to be solved with strong character interactions. It takes the usual antagonisms between different law enforcement agencies to a new level, turning heroes into villains, at times unjustly. The resolution of Scully’s case provides a strong finale followed by a bittersweet ending suggesting the series won’t end here.
