Only men are disappearing? Honestly there's so many possibilities I'm not sure what's happening! There's a chance the innkeeper might be involved, since there's a whole chapter about the family, but she doesn't seem "evil"! So blackmail or protecting someone? We seen someone leading those 3 werewolves, and they knew the one our MC defeated so they can not be newly transformed! But maybe he/they can "infect" others...like the children?
