Graham Masterton was born in Edinburgh, Scotland, in 1946. He worked as a newspaper reporter before taking over joint editorship of the British editions of Penthouse and Penthouse Forum magazines. His debut novel, The Manitou, was published in 1976 and sold over one million copies in its first six months. It was adapted into the 1978 film starring Tony Curtis, Susan Strasberg, Stella Stevens, Michael Ansara, and Burgess Meredith. Since then, Masterton has written over seventy-five horror novels, thrillers, and historical sagas, as well as published four collections of short stories and edited Scare Care, an anthology of horror stories for the benefit of abused children. He and his wife, Wiescka, have three sons. They live in Cork, Ireland, where Masterton continues to write.
