The Terrible Castle of Baron Castaign (2009)

From the introduction:

The Barony of Shufflemoore Woods is being plagued by wolves - or perhaps only a single wolf. The creature or creatures have been responsible for all sorts of deviltry, including the disappearance of livestock and, most recently, of Mitchell and Susannah Miller's youngest daughter. Now, several residents of the Barony have retreated to Shufflemoore Manor, seeking the protection of Baron Castaign.

User summary:

Game is intended as a single-evening live-action event similar to, but more complex than, a traditional "murder mystery" party event.
