The research in my novels is pretty carefully delineated. I have to do it: the OB-GYN with Dr. Larch in The Cider House Rules, the orthopedic surgery in A Son of the Circus, the business of granite quarrying and being a body escort in A Prayer for Owen Meany, even the prostitutes in A Widow for One Year. I feel I have to be the dutiful journalist. I have to put myself in the hands of someone whose life that is and learn it. You just have to know that stuff or you shouldn't write about it.
