Dick Hannay, under forty and already a successful Brigadier-General with good prospects of advancement, is called out of uniform by his old comrade, spymaster Sir Walter Bullivant, and sent to Fosse Manor in the Cotswolds to receive further instructions. He must pose as a South African, an objector to the war, and once more takes on the name Cornelius Brand (an Anglicisation of the name he had used on his adventures in Germany in Greenmantle). He is upset by the idea of such a pose, but comforted by thoughts of his friend Peter Pienaar, briefly a successful airman and now a prisoner in Germany, and by the beauty of the Cotswold countryside.
