Query: Consistency

John Grisham does a remarkable job in keeping his stories consistently believable and interesting. I've yet to read one of his books where I didn't have trouble putting it down. The Brethren takes you through the minds and schemes of people in jail looking to get back something they lost. Each has his personal agenda but must work with another convict to get what he wants. Trust is a necessary factor in a place full of untrustworthy characters. It's a whodunit that keeps you second guessing yourself right up until the end.
