Kennedy is a country doctor, and lives in Colebrook, on the shores of Eastbay. The high ground rising abruptly behind the red roofs of the little town crowds the quaint High Street against the wall which defends it from the sea. Beyond the sea-wall there curves for miles in a vast and regular sweep the barren beach of shingle, with the village of Brenzett standing out darkly across the water, a spire in a clump of trees; and still further out the perpendicular column of a lighthouse, looking in the distance no bigger than a lead pencil, marks the vanishing-point of the land.
