The Ghost of Matter

1886. Two young boys disappear in the Sounds. Their mother grieves, all the music cut out of her heart; their father wanders the coast for a year, wanting and not wanting to find any part of them left behind. And their brother Ern, faced with a problem to which no solution can be found, returns to his laboratory - and to the smell of salt, soft voices in his ear, wet footprints welling seawater in the darkness.
