Query: No Con: This is a great book!

Joe Gores -- one of the few mystery writers to actually have been a private investigator at one time in his life -- has written many acclaimed books over the years. Somehow, though, he has managed to fly under our radar here at Mystery Ink. We suspect it's due more to our inattention to any flaw on Gores' part. Based on the quality of this book, he goes right to the head of the class.Interweaving three complicated plots, along with at least a dozen significant characters, would be beyond the abilities of many writers. For a seasoned veteran like Joe Gores, though, it's a piece of cake. (At least, he makes it seem like it is. I somehow doubt it was quite that easy.) "Cons, Scams & Grifts" is one of the best mysteries I've read this year.--David Montgomery, Mystery Ink
