About This Murder Mystery Quiz

This murder mystery quiz is a celebration of the whodunit — the writers, detectives, books, films and board games that have kept readers guessing for nearly two centuries. Every question is multiple choice and drawn from the world of fictional mystery, from Sherlock Holmes and Hercule Poirot to Cluedo and the modern revival of the genre in Knives Out. There is no true crime here, just the pleasure of a good, solvable puzzle.

Choose a quick five-question round, a standard ten, or the full case of all twenty-eight questions. After each answer you will see a short, verified fact — a little extra colour on the character or case in question — so you finish knowing more than when you started. Correct answers light up green; a wrong pick shows red alongside the right one, so you always learn the answer. Your running score is tracked to the end, where you earn a detective rank and a result you can share to challenge a friend.

Prefer to deduce a case yourself rather than answer trivia? Try our companion Ravenwood Affair logic puzzle, a fair, fully solvable whodunit where no clue names the killer, or read the full murder mystery trivia guide for the story behind the genre.
