Publisher's Synopsis
Humphrey Paxton, the son of one of Britain's leading atomic boffins, has taken to carrying a shotgun to "shoot plotters and blackmailers and spies." His new tutor, the plodding Mr Thewless, suggests that 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.
