Anyone know of a "role playing game", and I use that lightly, that gives you the feeling of traditional D&D... but instead of D&D-like game play is more of a murder or other type of mystery? Can be fantasy, or not, but where you can buy like mystery stories and run a "campaign" where the players have to solve whatever mystery there is?
Maybe Gabriel Knight - a Sierra point and click. Old stuff. Maybe on GOG.
