September 18, 1922 not 1923.
Are you sure of that? My impression from your book (specifically, page 35; don't you just love it when people pick your work apart?) was that you were not. I like the 1922 date, though; it gives her an extra year of life.
Incidentally, I had a lovely time reading the book yesterday. My plan for the day had been to come home from my 12-hour shift, which ended at 7am, and sleep all day. Instead, I stopped off at the post office and picked up The Book, and read it in one happy gulp. Gosh, what an interesting person she was!
