That aside, I must confess that I find it a bit of a dubious proposition. People like to write along similar themes in their bodies of work, but that does not necessarily mean they are trying to convey a Sekrit Message. People have tried to cast almost every great work of literature since the world began into steganographic interpretations; witness the recent Biblical schlock movies based on that idea. I do think it makes a wonderful idea for a story, perhaps even a series of stories if well-written. But just as I cheerfully make up tales of alien abductions and weeping paintings and Elvis sightings and people cloning Hitler's body parts without believing a word of it, I really doubt there is any truth to this idea either.
Still, it will be interesting to see what you come up with. There is always the possibility that I may have to eat my words--though I rather doubt it.
(And I am still waiting on your responses to my previous posts, by the way.)
