From the introduction:
Sometimes investigators need a break from the horror and madness of the Mythos to partake in the horror and madness of the mundane world. This adventure holds out the promise of rest and relaxation, only to rip it away. Otherwise, obviously enough, there would be no adventure.
The adventure is set in the current day and takes place in the imaginary town of Deerfarm in the imaginary state of New Hampshire. With some modifications, it can be set in a different time or place.
This is a revised version of The Scarecrow (6e).
