And she'd simply vanished away. And there were two or three times when I had to call the police and they went and search for her, the police advised me to stay at home. And in fact she always, on the first occasion I think she came back by herself rather remarkably. But later on either the police managed to find her or sometimes a friend who I warned that she could be walking around came, brought her back home.

But in fact she had an uncanny way of avoiding trouble. She seemed to be able still to cross a crowded street and to know which way to look and that sort of thing as if this was a reflex which was very deeply embedded in the consciousness. And even Alzheimer's with its disturbance of the communications in the brain hadn't been able to eradicate.
