I have done a good deal of thinking during the late hours of software testing, while I am rereading and reworking the text, and as you may be able to tell, those who are doing a close reading, there are many subtle edits in there which are giving further depth to what landed Colson in Tourmaline, and why he felt obligated to stay to help Pete and Ellery, and now that we have the end product as evidenced by the story being completed up to January 1985, it provides an anchor for a view of Tourmaline that is far more literary and less literal.
For those who have never seen one, I got a small tumbled tourmaline for meditation purposes, and will throw up a photo of that when I have a photo in the clear light.
A smaller view of the stone is here / the first is a crysanthomite *or something - it looked pretty*, the second down is a green jasper, the smallest one with the purplish tinge, is the tourmaline.
