David M. Kiely's long career as a freelance writer has included biographies, short stories, crime novels, mysteries, and several works of nonfiction. When his spouse and co-author, Christina McKenna, was eleven, a paranormal "visitor" tormented her home for six weeks. Only through the intervention of an exorcist could the spirit be expelled. Christina would later recall this episode in a memoir, My Mother Wore a Yellow Dress, published in 2004 in Ireland to great acclaim.
Authors David M. Kiely & Christina McKenna spoke about their new book The Dark Sacrament, which documents ten contemporary cases of possession and exorcism, and the work of two elderly exorcists Canon William Lendrum, and Father Ignatius McCarthy.
