Bower, Barbara "Miss Ranskil Comes Home".

Part 1 of this Saturday Evening Post serial details prim Miss Ranskill’s unceremonious arrival on a deserted tropical island after having fallen overboard from a luxury liner on a world cruise in 1938. She is rescued by a ship’s carpenter, another castaway, and they live together for four years until his death, which occurs right after he had finished construction of a small sailing boat. Miss Ranskill takes the boat to sea and is ultimately rescued by a British navy vessel, sailing in convoy back to England. The succeeding serial installments record the immense changes that England had undergone because of the Second World War, all seen through the eyes of the newly-returned Miss Ranskill. Later published (see next entry) as a novel.
