"Colonel Grant's activities - his very existence, for he is living under an assumed name in the heart of the country - are revealed by chance and become the centre of a plot among certain of the convicts in Dartmoor Prison, wherein the early chapters rise to the high drama of a mutiny. The stage is then set for civil war in Britain; engineered by agents of a foreign country, synchronizing with the outbreak of international hostilities. The tale leaps from one adventure to another, swift, blood-curdling, forceful, while the country, despite the precautions of the Government, is given over to an orgy of revolution. From the chaos of starvation and sabotage, Duncan Grant ... emerges triumphant as the herald of a new order."
