Honore de Balzac 
Exiles [PDF ebook] 

Though Honore de Balzac is now lauded as a master of the literary genre of social realism, a sizable number of his stories and novels also contain supernatural and mystical elements. The story "The Exiles" is set in the medieval period, and revolves around a couple who run a small boarding house — and gradually begin to suspect that some of their boarders may be harboring dark secrets.
