mullingar, one thing which has been missing on this thread - though I can't swear to have read every post - is the connection between the title of the work in which the 4 Ladies appear and the meaning of that title and its associations and connections. This is absolutely central to the endgame. Think about it long and hard and if you don't come up with something, think some more.
I hope I haven't overstepped any boundaries but, if I have, please feel free to report it and take it down. I'm having surgery tomorrow so frankly,my dears, I don't give a damn!
