Jersey 1987, and the storm clouds are gathering over Colin Bygate. Sitting on a headland stewing over the discovery that his wife used to date Rob de la Haye, a brash hotelier who is everything that Colin is not, he spots a pupil near the edge of the cliff. Worried that the boy may have intended to jump, he drives him home, hoping that his gloomy imagination was playing tricks. But when the boy fails to turn up to school the next day, Colin feels duty bound to track him down, pitting him against the Island establishment who would rather there was a little less noise around this particular absence.
A web of characters is spun around this mystery, each with their own secrets. For living on Jersey, where everyone knows everyone else's business, you must become your own island.
