FAQ
Frequently Asked Questions
No, it is an informal, playful term coined from non-standard English 'who done it?'. For formal writing, use 'murder mystery' or 'detective novel'.
Both are correct and commonly used. 'Whodunit' is slightly more common in American English, 'whodunnit' in British English, but the distinction is not strict.
Its core meaning is a murder mystery. Informally, it can be extended to any situation where the key question is 'who did it?' (e.g., 'The cake is gone—it's a real whodunit!'), but this is figurative usage.
A whodunit is a specific type of mystery where the puzzle of the murderer's identity is central. A thriller is a broader genre focused on suspense, excitement, and tension, which may or may not involve a mystery about the perpetrator.
