Publisher's Synopsis
I do not think a book of this sort requires a very lengthy foreword, but one or two things I feel it necessary to say concerning it. In the first place, I have to thank Mr. Hamilton Edwards for many valuable suggestions concerning it, suggestions which, undoubtedly, helped me very much in the writing. The story is an attempt to impress upon readers the fact that we are, without doubt, surrounded on our way through life by unseen presences, unseen intelligences, which guard or attack that real portion of us which is ourselves-the soul. Superficially, but only superficially, this is a very material age. We are surrounded by so many material wonders that the unthinking person is inclined to believe, at any rate to state, that the material is everything. Yet there is nothing more unsatisfying than the purely material aspect of life, after all.
