The Journeying Boy

Humphrey Paxton, the son of one of Britain's leading atomic boffins, has taken to carrying a shotgun to 'shoot plotter and blackmailers and spies'. His new tutor, Mr. Thewless, suggests the Humphrey might be overdoing it somewhat. But when a man is found shot dead at a cinema, Mr. Thewless is plunged into a nightmare world of lies, kidnapping and murder- and grave matters of national security.
