Cymbeline

Cymbeline is one of Shakespeare's late romances, which (like The Tempest and The Winter's Tale) combines comedy and tragedy. Imogen, the daughter of King Cymbeline of Britain, angers her father when she marries Posthumus, a worthy but penniless gentleman. The King banishes Posthumus, who goes to Rome, where he falls prey to the machinations of Iachimo, who tries to convince him that Imogen will be unfaithful. Meanwhile, the Queen (Imogen's stepmother) plots against her stepdaughter by trying to plan a match between Imogen and her worthless son Cloten. (Summary by Elizabeth Klett)
