Overview: In the village of Chelton, just outside Fulchester, an elderly man is knocked off his bicycle and killed by a speeding green Mercedes convertible. The car is traced to a local wealthy businessman who now needs to explain why the car in question was taken to a local garage for repairs within hours of the incident. The accused denies causing death by dangerous driving. His defense counsel are claiming that the policeman dealing with the case held a grudge against the accused ever since a previous attempt to prosecute him on another matter proved unsuccessful.
