The Inner Circle: A Mystery

The Inner Circle opens with an international group of young archeology students sweating on a dig on the island of Gotland, uncovering a Viking fortification dating back over a millennium. They are a fun-loving lot, partying together every night, but the good vibe turns to horror when one of them, twenty-one-year-old Martina Flochten, disappears. Her body is found a short while later, naked, bled out, and hanging from a tree. Her injuries indicate that she is the victim of a ritual killing.
