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

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.

Only towards the end of this process are any of the chapters in fully readable condition, a state of affairs that used to alarm my wife. But Joan's got used to it.

My gut feeling is that paper and ink are going to be with us for a long time yet, and in substantial quantities, though certainly books are now going to be available in other forms.

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

If people ask me for the ingredients of success, I say one is talent, two is stubbornness or determination, and third is sheer luck. You have to have two out of the three. Any two will probably do.
