Webb Carrick of the Scottish Fisheries Protection Service latest adventure takes him on a North Atlantic shark hunt in the waters of the storm-tossed Hebrides. Webb Carrick finds he has inadvertently strayed right into the middle of a smouldering feud between a renegade band of shark hunters and some vengeful local fishermen, angered by the drowning of a young girl - a feud which threatens to ignite when he boards a wrecked fishing boat and finds her skipper dead on deck. As furious charges and counter charges are hurled, murder and arson come to the islands with stealthy suddenness. But when the final stormtide breaks even Webb Carrick is staggered to discover how much is at stake in terms of life and death.
