The Case of the Great Underwater Panther

From publisher blurb:

This is a playable Story for the Coyote & Crow roleplaying game. While it is a stand alone story and can likely be played in a single evening, it can be easily integrated into any larger Saga. You’ll need the Coyote & Crow Core Rulebook to use this story.

Synopsis:

Copper shipments are being hijacked on the river just outside of Cahokia, and the surviving crew members swear it's the work of the great underwater panther, Mishepeshu! Can the players get to the bottom of this mystery before an old schoolmate's grandfather loses everything?
