When you keep having ghosts haunt the town, maybe there could be an exorcist? But when you pay the exorcist the town becomes a little sad? It would be a hard choice because it would cost you a lot of gold, but they wouldn't keep scaring the town's people. Also it would effect the witch's happiness because she didn't want the ghosts to leave. It would also make Monsieur Esprit sad because those were his friends?
