Two of the most entertaining Adventure Books I've played was werewolf centered. Secret of Monarakh by Garry Hamilton and Catch the Beast by Jim Caldwell. Both of them feature a plot to uncover some mystery murders, done by beasts. At first, the blame goes onto undeads, while in the other book it's straight up a werewolf...and then they feature 2 werewolf, one wolfwere, a werebear, a True Werewolf, and some more suspects...to sort out and hunt down the true murderer or murderers is up to you, but be prepared for an epic twist in each of those books! One of the best story pacing and also subtle hint dropping on who the real threat is in both books.

The neat element was in one of those book, is to choose your weapon: You either used a silver weapon, or a magical one, but in the end, you were in need o more down-to-earth means of dealing with the twist-bosses! Liked the part where the monster-expert asked you what metal to use against werewolves. If you answered "Gold" the monster-expert only said: "Gold is effective, but against humans, not as a weapon but in the form of coins." What a great line!

Haha sounds pretty awesome. It isn't often you get a well written module like that coming along.
