Convergences: Maria de Zayas, Spain's 17th century exploitation filmmaker
In "Too Late Undeceived," Don Martin sleeps with an unknown lady, falls desperately in love, and later finds and marries her. But a female slave falsely informs him that his wife has had an affair with her cousin. Don Martin burns the cousin alive and locks his wife in a kennel, forcing her to drink from the dead man's skull and eat only scraps from his table. As a reward, the slave becomes Don Martin's mistress, but two years later, gravely ill, she admits that she lied. Don Martin stabs his mistress to death and rushes to free his wife, who has just died of a broken heart. The man goes mad. (75)
