All I can do is agree with what others have written. The clunkiness of the dialogue, the patronising undertones (not really undertones - that would suggest subtlety), and the remarkably offensive racial and religious stereotyping are staggering. The characters are supposed to be the greatest investigative minds in the UK, yet they routinely spout banalities, rely on pure luck and coincidence for any advance in their investigation, and miss the most obvious clues on their route to dramatic 'success' (although is there any way they would allow a key London landmark to be blown up, just because the SAS had run out of one particular type of missile - "Oh well, can't be helped - still, we got most of 'em, eh?")
I'm often fed up with political correctness, but has anyone counted how many times a male colleague has to reassuringly pat or squeeze Paula's trembling shoulder? Or how often brown skin immediately identifies someone as a terrorist? Or likewise a turban?
The one amazing thing was that I still wanted to find out what happened at the end. I do agree with another reviewer that some of the action sequences were quite well handled, as long as they avoided any of the excruciating conferences held between the investigators.
Throughout this book, I kept saying to my family, "I can't believe how badly this has been written!" When I got to the end, I seriously expected a page at the end saying that the book was a spoof, and that the author was making deliberate mistakes to show how it shouldn't be done.
I think it's fair to say that I don't recommend this book, unless you're wanting to write a novel yourself and need some pointers as to what to avoid.
