On a stormy night in March 1941, Maisie Rose Hawkins leaves her drunk husband, Stan, out in the rain-and he disappears. Detective Sergeant Bob Robbins and young PC Laurie Oliver are called out to investigate and discover that Stan's small fishing boat is gone, the rope sawn through. As Bob searches for answers, it becomes apparent that in this small Cornish village where everyone knows everything about everybody, nobody quite knows the truth. Beneath the surface of village life, a fierce battle is being waged against wartime deprivations. Shopkeepers quietly evade rationing restrictions. Food inspector Archibald Bantry, charged with enforcing those restrictions, dies in a suspicious car crash. Various leads connect a sea cave full of smuggled black-market goods to the missing Stan Hawkins. And what seems like the work of local malcontents becomes more complex and dangerous when Bob stumbles on the truth in a disused copper mine, where a much deadlier affair is underway.
