A reading of author Helen Dunmore's atmospheric Cornish tale that will grip both adults and children, written specially to accompany 2009's Family Prom.
Inspired by the world Dunmore created in her celebrated Ingo series, the story is set on a remote Cornish island, where tales of King Arthur, ghostly lost souls and musical mer people have become part of the folklore.
Music, too, is a big part of the close-knit community, with the Cornish bodhran, harp and penny whistle at the heart of its unearthly sound.
One day, one of the villagers, a gifted young violinist, disappears.
He is usually to be found on the beach, where he seems to take inspiration from the sea itself.
When the villagers find him standing at the water's edge, his haunting violin is not the only instrument piercing the night sky - he seems to be being accompanied by the waves, or perhaps something in them.
