Ever since her eighteen-year-old son, Erik, mysteriously vanished on a boat over thirty years ago keeping busy has helped her cope. One night she meets Marcellus, a giant Pacific octopus living at the aquarium who sees everything, but wouldn't dream of lifting one of his eight arms for his human captors – until he forms a remarkable friendship with Tova. Ever the detective, Marcellus deduces what happened the night Tova's son disappeared.
