On the small island of Marabhal, all sorts of things suddenly disappear: a fishing net, stacks of wood, a pair of binoculars. Some of the children suspect Abdullah, a Syrian boy who arrived on the island just a month ago. Annie and Ruaraidh don't believe Abdullah is guilty and are determined to solve the mystery-and find their father's binoculars, too.
