Query: You'll be mad if you read this book

Caveat: I'm not a huge Grisham fan, so I'm sure some bias has slipped in here. But I think this book is just awful. While his other books are at least entertaining, this thing dies quickly after a semi-decent premise. The biggest problem is that there's only about 50 pages worth of story, and a writer with his minimal powers of description can't get away with hundreds of pages of fluff. Don't read this book--read Presumed Innocent instead.
