Two brothers, John and William Rother, live together at Chalklands Farm in the beautiful Sussex Downs. Their peaceful rural life is shattered when John Rother disappears and his abandoned car is found. Has he been kidnapped? Or is his disappearance more sinister - connected, perhaps, to his growing rather too friendly with his brother's wife? Superintendent Meredith is called to investigate - and begins to suspect the worst when human bones are discovered on Chalklands farmland.
