Mysteries I read for fun, so I will probably never write one, for fear of spoiling the fun.

And what we know, or think we know, about the universe of space and time is changing very quickly.

I don't know why a computer game can't be an art form just as a puppet show or an opera is. I'm still interested in computer games as something I would like to work on someday.

I wouldn't like to just do one story or one type of stories all the time.

I suspect that writer's block afflicts mainly people who have some stable and ample source of income outside of writing. So far it hasn't been a problem.

Probably all the books I've ever written have been efforts to define the boundaries of humanity.

The comments I most appreciate come from ordinary readers who've happened on one of my books at some time of stress in their lives, and who actually credit the book with helping them through a bad time. It's happened a few times in forty years.
