Frank Zotter Jr. of the Ukiah Daily Journal has a very ineresting article about a lawsuit brought against King by a woman claiming he stole her story. Christina Starobin claimed Despration was a rip off of her book "Blood Eternal" which she gave to Penguin in 1996. The judge read both books, was unimpressed with both (what's wrong with him?!) but decided in King's favor.
Now imagine how this would happen. King hits major writers block. He has to beg publishers at Penguin to let him steal Starobin's work. Right! I do not think that's how King gets his ideas. No more than I think he gets them watching the Simpsons.
Read the story here, it is interesting:
