Skinners

From the back of the adventure:

"The Skin's the Best Part!

At least that's what someone on-board the riverboat Marie Belle seems to think. What started out as a simply voyage up the Mississippi River gets a lot more complicated for Ronan Lynch when bodies start turning up minus their birthday suits! If Ronan can't figure out who-or what-is behind the gruesome slayings, the Marie Belle's trip from New Orleans to St. Louis could be its very last."
