Below are links to some mystery games, many quizzes, some of them trivia. The quality of these can vary. Sometimes the answers require an unfair exactness or mind-reading, e.g., Sherlock Holmes sidekick: Dr. John H. Watson. (Not John Watson or Doctor Watson. Other times the trivia quiz creator was more generous in allowing alternate answers. I've tried to present the best up front and for those desperate for more, they can follow the links to further games. (Note: the term mystery gets used for a number of purposes in these quizzes, such as Who is this mystery actor? when his identity is a mystery, not that he had a career in mysteries.)
