Crime and detection is one of a series of six Grandmaster Quizzes, in which you can pit your knowledge against a grandmaster of the subject. The writer's specialised skill and expert knowledge makes the quiz both challenging and exciting. Each program has thirty sections of ten questions - a massive 300 questions in all - and you can take the quiz alone, in competition with a friend, or in teams. You can choose a timed option too - and if you're getting too many of the answers right, your computer can reduce the time you have to answer!
