A night drive across Dartmoor in a gale, beside a doctor who will not turn back, is only the beginning for Betty Carew: behind it stands a secret brotherhood, the Sons of Ragousa, which works with poison and patience and has men in places nobody would suspect. Bill Holbrook sets out to break its grip, and the chase runs from the moor to London and out to sea. Wallace at his most efficient: the plot moves, and nobody is safe. Fifty-eight plates of paintings from 1850 to 1922, among them Sickert's London streets and Brighton Pierrots, track the story's course from the moor to the city and out to sea.
