And this pic in your post 220, looking at it again just now, I think we are seeing her left knee. The black bump. And her right foot, the one in the sock.
Yep, maybe left knee, right foot, either wearing shoe or sock. But where’s her head? If her head has slumped face down into the water, that brown/black bump is her hair. And the shiny black object, where is that now? It seems to have swam away...
I think I’ll have a coffee.
