Cluedo is one of the most popular games with a detective theme. In this game you try to find the murderer throughout clues you get. This fits perfectly in this theme because it is a mind game. Detectives/ crime solvers do the same. Even though it is a game, it could be nice to be the detective some time.

I do like this game, although I miss some cards to solve the murder cases. After a couple of games you already know the clues and the plots. Then it will become a bit boring to play, luckily extension sets exist.
