Since 1985 I've published 18 novels, including 16 Delaware books, translated into a couple dozen languages. I'm not frustrated by writing a series. Alex Delaware is a terrific vehicle for telling a certain type of story, one that explores the unpredictability of human nature. A series imposes limits, and I do my best to test them. Delaware and Sturgis go through life changes, including the aging process, though their maturation occurs in mercifully slow time.
