The Slow Death Cap looks, to those who don't know what they are looking at, like an edible mushroom, but eating it is one of the most unwise things anybody could possibly do.
Ursula is a were-bear; she and Stewart, the bailiff of a rural feudal estate, are lovers, sharing all their secrets as lovers often do. Recently something has been taking livestock. *He* must deal with suspicions that a bear is involved (one has been seen nearby...): *she* must defend herself if it is revealed (perhaps by a jealous suitor, perhaps accidentally) that she is a lycanthrope. The adventurers might be called in to track the hungry beast(s) and discover her secret, but be able to reveal that the culprits are a small pack of wolves that has moved in to the area. The adventurers might earn the gratitude of both Ursula and Stewart, depending on what they reveal, and to whom.
