Measure For Measure by David Finch

Set in a morally strict Vienna, a ruler temporarily hands power to a zealous deputy who enforces harsh laws and condemns a young man to death for premarital sex; the condemned man’s sister, a novice nun, pleads for mercy and is met with a corrupt proposition that exposes the deputy’s hypocrisy, while the ruler—disguised as a friar—orchestrates a plan involving the deputy’s jilted former betrothed to reveal the truth, leading to the deputy’s public disgrace and punishment, the condemned man’s reprieve, and a bitterly ambiguous examination of justice, mercy, sexual politics, and the abuse of authority.
