THE main purpose of this story is to appeal to the reader's interest in a subject which has been the theme of some of the greatest writers, living and dead-but which has never been, and can never be, exhausted, because it is a subject eternally interesting to all mankind. Here is one more book that depicts the struggle of a human creature, under those opposing influences of Good and Evil, which we have all felt, which we have all known. It has been my aim to make the character of "Magdalen," which personifies this struggle, a pathetic character even in its perversity and its error; and I have tried hard to attain this result by the least obtrusive and the least artificial of all means-by a resolute adherence throughout to the truth as it is in Nature.
