Some fancy sleuthing by the juniors, a luxuriance of loose threads, and a race against time with a slim margin for error, in this bustling mystery-thriller. When Mick and Caroline arrived at an old ""forgotten"" village on the Thames for an intense few weeks of cramming and exam-tutoring, they found themselves involved in a mystery concerning their solemn secretive housemate, David; the , a ship soon to be purchased by the village grocer; O'Leary, a slippery character; Joe, a British Fascist; and a beer delivery route. In league with the Prettyman Hard Chaps-four village children -- Mick and Caroline track down a smuggler and a plot to slip some explosives into the House of Commons.
