What are some good "first-time Keeper" scenarios for Call of Cthulhu? Especially ones that aren't The Haunting?
A friend of mine in my Horror on the Orient Express game wants to try being Keeper for a one-shot. Unfortunately, I have already run most of my group through The Haunting myself to make that a viable option. This will also be his first time GMing any kind of game, so something much more on the simple end would be great.
