Mr Justice Grampion hates dangerous drivers and believes it is his duty to give very severe sentences to those who offend. He is well-known for his opinion on the matter, so, when Michael Barnes, MP, is to be tried for a very serious motoring charge, he is devastated to hear that Grampion will be the judge. To make Michael's problems worse he has no witness to support his story. Ranged against him are a host of independent witnesses whose testimonies are hilarious and often contradictory. While this is another highly amusing novel from Henry Cecil it also examines the serious nature of truth and reality as perceived by different witnesses.
