From the introduction: It's 8 PM on a December evening and it's pitch dark and soon the UFOs you've been chasing will be out and about again. But after 9 days of tracking and barely missing them, everyone needs a good meal and a good night's rest. "There, pull off up there. That place has to have some rooms." Fed up of the complaining and feeling tired and hungry, you pull off into the quiet Scottish town of Castleton.
