"I was in my forties and teaching magazine writing for the Journalism Department at the University of New Mexico. I was hired on a fluke. The professor who was scheduled to teach the course became ill, so the chair of the department, my personal friend Tony Hillerman, asked me to fill in for a semester. Tony knew I’d never been to college and didn’t care; he just knew I’d written successfully for magazines for years. The original professor never returned, and someone else replaced Tony as Chair and automatically kept me on. I discovered I loved teaching writing and started to get worried that my deep dark secret, might be discovered, so I began taking courses under my married name, Lois Arquette, hoping I could get a degree before someone “outed” me. In the course of that endeavor, I took a juvenile literature class where they were studying “Lois Duncan books.” My fellow students were excitedly writing A-plus papers about how many of my books were based on Greek myths. I had never even read those myths!"

“The subject matter of today's youth novels has no boundaries. The only taboo seems to be sex discrimination... I can only guess about where we're going, but I think we have come about as far as we can in the direction of 'let-it-all-hang-out' realism. My reader-mail indicates that kids are beginning to feel bogged down with so much depressing slice-of-life. My own most successful books have been those that were high in entertainment value, especially those touching on the supernatural.”

“Killing Mr. Griffin doesn't encourage violence in schools any more than the story of Cain and Able encourages children to kill their younger brothers.”

“The books I loved most as a child were those that contained elements of magic—the whole series of Oz books, Mary Poppins, The Princess and the Goblin—I could name them indefinitely.”

“A movie loosely based upon my novel, I Know What You Did Last Summer, opened in theaters around the country. I was ecstatic until I settled into a theater seat with my box of popcorn and discovered that Hollywood had turned my teenage suspense story into a slasher film. The setting had been changed from the mountains of New Mexico to a fishing village on the East Coast, so an insane fisherman, who wasn't in my book, could decapitate my characters with an ice hook. The first thing I did after leaving the theater was phone our daughter Kerry and warn her not to let the grandchildren see it.”

“I cannot remember a time when I did not consider myself a writer.”

“It came naturally. I came from a family of strong women.”
