I wondered if I might not be in the grip of demons, if they were not making me suffer for their own purposes, or simply for their enjoyment.

I put the copy of 'A Christmas Carol' that my grandfather had first read to me 60 years ago on my desk, and I began to write. The result, for better or for worse, is the 'Christmas Spirits.' I plan to read it to my grandson.

In them was not the savage blankness of the reptile species. Instead there was something far worse - burning, unquenchable rage mixed with the self-mocking irony of great intelligence.

I've always been interested in definitions, because in the Bible, the Ten Commandments are there but there's no real clear definition of what sin is, in a fundamental sense - how we can use the words to evaluate our lives as we go along: Am I doing something that is ethically good? Am I being worthwhile in my life at this moment?

I became entirely given over to extreme dread. The fear was so powerful that it seemed to make my personality completely evaporate... 'Whitley' ceased to exist. What was left was a body and a state of raw fear so great that it swept about me like a thick, suffocating curtain, turning paralysis into a condition that seemed close to death...I died and a wild animal appeared in my place.

Increasingly I felt as if I were entering a struggle that might even be more than life and death. It might be a struggle for my soul, my essence, or whatever part of me might have reference to the eternal. There are worse things than death, I suspected... so far the word demon had never been spoken among the scientists and doctors who were working with me...Alone at night I worried about the legendary cunning of demons ...At the very least I was going stark, raving mad.
