Who would go and use eight different aliases over a six-month period at hotels in the region?
The other odd thing...she visits the region in March/April....then disappears, and reappears in late October. So where was she for seven months? She comes right back to the region for what purpose?
My bet is that she was a Stassi (DDR) agent. She failed them in some way, and was terminated.
State sponsored sex worker.
Having the love child she had with she fell in love with the handsome double agent ?
I can sell this idea as a screen play ! Two lovers caught between ideology and love !
