The twins were born in war-torn Plymouth in 1944, two little girls whose parents - touring actors - didn't altogether want them. Their unorthodox childhood, first as evacuee babies in Cornwall, then at boarding school, then living with their Aunt Maggie, made them grow up uniquely self-sufficient. They didn't need anyone else. They had each other.
Miranda was the vibrant, flamboyant one, determined to be an actress, determined never to conform or be dull and conventional. Meg was quieter, more self-effacing. But it was Meg who always knew when anything bad was happening to Miranda.
As they grew up, the bond between them held - until Meg went back to Cornwall to buy a house, to paint, to fall in love. And for the first time events conspired to drive a rift through their special relationship. Their lives shifted - for Miranda found herself trapped into domesticity, and Meg - feeling herself betrayed - had to seek a new path that ultimately took her to unexpected success.
But the link was still there, in spite of all that was to happen, in spite of violence and tragedy, and finally it led to happiness that came when they had ceased to expect it.
