Being married to a Brit I'm fairly used to the slang and what we American's call poor grammar, but this book took the cake. There were so many grammatical errors, misused words, misspelled words, and British slang being used by LA detectives, it took the readability right out of it. I might recommend this book to some of my 'illiterate' friends only because I know they'll never read it. It got 2 stars because there is potential with the story-maybe a complete rewrite and relocate it to London. Police procedures-not even close. And when Patton finally takes on Caldwell, he fails miserably and his backup, while only mildly wounded, doesn't even get a shot off or see where the suspect disappears to? I could go on and on, but suffice it to say that I won't be reading any more by this author unless he learns to proof, edit, and research his material beforehand. Sorry Simon, but this is the type of work that gives self-publishing a bad reputation, and I don't say that lightly.
