For the fashionable and affluent Randolph Buntings, it was just another day at the beach - that was until Fred spotted a mysterious lady in a red dress and Phrygian bathing-cap getting into difficulties far out at sea.
Embarking on a brave and daring rescue attempt, Fred waded in and brought her safely to shore. The family applauded warmly - after all not every day had such excitement.
It was only later that they spotted that this lady wasn't quite "normal" - in fact, to be precise, she had a tail. For it seemed the Randolph Buntings had been visited by a mermaid.
