So I just decided to run a short mystery scenario on New Year's Eve for my wife and daughter. I'd like to do a 1920s-ish, non-supernatural mystery they can investigate and solve. Preferably not a murder. The point is to introduce them to BRP, and get them interested in a supernatural investigation next, and finally lead them into Call of Cthulhu adventures. Now I've got some Cthulhu stuff that I haven't looked at in years, but I don't think there's anything suitable. Can anyone point me to something, maybe online, that I could grab in time? Thanks!
