Young Letitia Hopkins, orphaned and ungratefully living with her great-great-aunt, is told to never even think about going through the little green door at the back of the house—a door that doesn’t seem to lead anywhere because there no egress on the outside where the door should come out. So, of course (this being a proper morality tale), Letitia goes through the door first chance she gets, and finds herself among Injuns and her own ancestors.

I’ve seen many references to the 1910 release of The Green Door in a slim volume (Illus. in color. Moffat Yard. 75 cents net.), but a 1911 review in the New York Times indicates that the story was first published “in a periodical some eighteen years ago.” I haven’t tracked down what that periodical was, so for now I’ll just list the story as being from 1893. I see that the story also appeared a few years later in the Times itself (13 Apr 1896). The wilkinsfreeman.org site lists the 1896 publication as the first, but that contradicts the later Times review.
