In some of my former novels the object proposed has been to trace the influence of circumstances upon character. In the present story I have reversed the process. The attempt made here is to trace the influence of character on circumstances. The conduct pursued, under a sudden emergency, by a young girl, supplies the foundation on which I have build this book.
The same object has been kept in view in the handling of the other characters which appear in these pages. Their course of thought and action under the circumstances which surround them is shown to be (what it would most probably have been in real life) sometimes right, and sometimes wrong. Right or wrong, their conduct, in either event, equally directs the course of those portions of the story in which they are concerned.
In the case of the physiological experiment which occupies a prominent place in the closing scenes of The Moonstone, the same principle has guided me once more. Having first ascertained, not only from books, but from living authorities as well, what the result of that experiment would really have been, I have declined to avail myself of the novelist's privilege of supposing something which might have happened, and have so shaped the story as to make it grow out of what actually would have happened—which, I beg to inform my readers, is also what actually does happen in these pages.
