I Play Board Games

I often play board games with my kid (just to get her away from youtube for a while) and she has just asked me a question I realise I can't answer about Cluedo:

If it is indeed about you being a detective gradually working out a murder, why would you also need to spend the entire game working out the 'where'? In reality the 'where' would surely be established when you arrive in order for the body to be examined (and thus answering the questions of who and how)?

Maybe she is just looking too deeply into a game that is generally just used as a form of entertainment, on the other hand it is meant to be thought provoking.

If anyone knows how I can answer this increasingly inquisitive child I would be grateful 😊
