UPDATED:
Although I do not know where she is, Lizzie just responded to an email message that I had sent to her with a sinle-word reply: "Safe". Again, I thank you for the outpouring of concern, help and ideas, and will keep you all posted. By making this contact I am first of all, reassured that she is not presently in grave danger, and I am hopeful that she may be coming in from the cold. God bless you all! Stuart"
