"A Blot in the 'Scutcheon" by Robert Browning is a tragedy in blank verse published and performed in 1843. When Earl Thorold Tresham learns of a secret lover climbing to his sister Mildred's chamber, his wounded family pride drives him toward vengeance. He cannot see that the mysterious intruder and Mildred's honorable suitor are the same man. This tale of passion, honor, and devastating misunderstanding moved Charles Dickens to tears and showcases Browning's power for tragedy, though its brief initial run was marred by backstage jealousy.
