He really has lost the plot since the 90s. Some of the latter books are even more crazier.
It was always thought that he had not actually written the books for ten years but you could imagine him supplying the plot outlines. It will be interesting to see if it gets less right wing now he has died and I wonder if they will still put stuff out with just his name or they will add the ghostwriter too - like they did with Frank Herbert and Robert Jordan.
