Investigator Cal McGill uses his knowledge of tides, winds and currents to solve mysteries no-one else can.

Five years ago, fourteen-year-old Max Wheeler disappeared from a remote Scottish island. None of the six police and private investigations have been able to shed any light on what happened.

But unable to let go, Max's family call in Cal McGill - known as 'The Sea Detective' - hoping he'll force the sea to give up its secrets.

Yet Cal finds he is an outsider to a broken family, and an unwelcome stranger in a village which has endured years of suspicion.

Cal knows that a violent storm is approaching. But what he doesn't know is that when it cuts off the island, a killer will see their chance . . .
