Following the strange events of the previous day, Alison and Gwyn explore the local legend of Blodeuwedd. She was a beautiful mythical woman created out of flowers - but later turned into an owl as punishment for being unfaithful. Could there be a connection between this and the plates? Roger also becomes fixated with the mysterious standing Stone of Gronw - named after the lover of Blodeuwedd in the story. Later that evening the mystery deepens further as Gwyn and Roger's father witness a strange revelation in the billiards room.
