From the back cover:
"First, you find yourselves in the Gnarley Wood, fending off minions of the evil leprechaun who dwells there. Coming through this episode with flying colors, you continue to the Free City of Dyvers, where there has been a rash of break-ins at several inns. Who is responsible for these crimes? Evidence leads you to believe that a full-sized person can't have committed the burglaries - the apparent entrance points are far too small, and the footprints aren't those of humans or even demi-humans.
It's up to you, adventurers, to solve this mystery and collect the reward (if you can).
This adventure is adapted from two RPGA network tournaments."
