The town of Silverfox Mill was a quiet place for many years, but this peaceful town has begun to unravel. The arrival of the Usury Guild drained the populace of their livelihood, forcing many into poverty, alcoholism, and prostitution. Complicating this trying time the town has recently lost its most beloved citizen, the wizard Osric Skanderbag. With his absence it seems the long-dead witch Anna has been raised to murder and poison, but this may be a front for more contemporary threats.
A vicious murder happens in a town that the party happens to pop in at. Under heavy suspicion as they are strangers, the party is forced to discover the perpetrator or have their reputations blackened, especially as more and more murders occur in the town, and mysteriously stop and restart when the party leaves to go kill off that evil necromancer who kidnapped the princess.
The only problem is that a demon, possessing one of the party, is the perpetrator. And the demon makes no signs that its living in the PC's head.
In fact, for all the party knows (except for the possessed person's), their companion is an evil murderer.
Do they try and execute their friend as he's a vicious murderer, and no evidence points to demonic posession? Or do they flee town with him, trusting him, and have their reputations destroyed?
