Query: Good Murky Work!!

"Mississippi Mud" is a well-written, murky, dark, mysterious true crime novel. Two parents are murdered and the author leads us through a trail of suspects, motives and some dead ends. The Mississippi Gulf Coast is an appropriately evil place. I don't wish to give the ending away, so I'll keep the review brief. If there is word to describe the ending, it's "muddy". This story is a safe choice for devotees of crime tales. My only question is: "Where is the Movie"? The cover mentions a forthcoming "major motion picture". Where is it?
