Robert McCammon hinted about this at the launch for Cardinal Black at the Alabama Booksmith on April 20, but stated that he couldn't say much because it hadn't been "papered" yet. (The contracts had not been signed.)

Speaks The Nightbird is one of my all-time favorite books and I hope that FX does it justice. It's not a horror novel as the article states, it's a historical fiction mystery novel. McCammon's work has been ripe for this sort of adaptation for years, let's hope that this is the start of something big.
