Of course it’s speculation. This is all speculation. I simply asked a question about something that doesn’t make sense to me. Leaving aside the very big issue of taking an international flight of many hours duration while very pregnant. In 1961. That also makes no sense to me.
Stanley was basically his plaything side mistress. Why would he take her to his village, when she didn’t know about the real wife and the real wife most likely didn’t know about her??! Hello! And maybe he felt the risk of being seen in Nairobi with her was too great, having too many contacts there. “Hi real wife, guess who we saw in the Capitol today with a young, cute, pregnant white girl? Yes, that’s right, your husband.”
Maybe she flew into Mombasa instead of Nairobi. It’s speculation. And a strawman. You know very well there can be no definitive answers.
Nothing Ann did in 1961, or afterwards, makes any sense.
