Annasmom, thank you very much. Given the date on the postcard (1978), and the dates on these earlier communications, I imagine there is a fair chance she didn't know his surname, otherwise she would probably have used in on the postcard. It seems they may have made up after the drama of 1977, at least enough for her to send him a postcard from her holidays. The more I look at these communications, the more twisted it all appears. I need some time to think this over. Thank you again.
