Paradise is on Earth and when Adam and Eve were sacked from it they only had to cross the narrow strip of desert to Africa. Then things started going pear-shaped (Africa did) and masses of land separated, isolating the Paradise from the rest. Until we found it again.
The heroine and heroes from “Home and About” came along. They had a whale of good time. Their story there will be told. They had never been to Paradise before and didn’t quite believe it existed so you can imagine their surpise!
