The Little Demon - Fyodor Sologub - Bog

Mad, lascivious, sadistic and ridiculous, the provincial school teacher Peredonov torments his students and has hallucinatory fantasies about acts of savagery and degradation, yet to everyone else he is an upstanding member of society. As he pursues the idea of marrying to gain promotion, he descends into paranoia, arson, torture and murder.
