THE STRANGER IN PRIMROSE LANE

Six London children of three different families, in a German spy chase -- necessarily clandestine since they do not want to implicate a soldier-father in revealing troop movements. Having decided that the stranger, for all his believable story, is a spy, they plot to keep him under surveillance, destroy any chance he may have to communicate with confederates, and to give him no opportunity to pick up any other information. They also have to evade two other strangers, who may or may not be spies or British Secret Service...and through their combined talents, intelligences, plans, they hang to their man, even in a chase to the East Sussex downs, and capture him for the government. Believable -- very real children, with faults as well as virtues, with squabbles subdued to the common good.
