Research is of considerable importance in certain fields, such as science and history.

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.

I finally decided one day, reading science fiction magazines of the time, I could do at least as well as some of these people are doing. So I finally made a serious effort.

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

I have some good stories yet to tell.

I started writing seriously about 1960, at the fairly advanced age of 30.
