Miss Scarlet on Masterpiece

When her father dies, Eliza Scarlet finds herself facing a difficult choice. As an unmarried woman, she faces poverty without a husband to provide for her -- unless she takes on the challenge of running her late father's detective agency, which would be unthinkable for a respectable Victorian lady. Fortunately, she finds an unlikely partner in the unconventional Detective Inspector William Wellington of Scotland Yard, known as "The Duke," and the pair begin to tackle the crimes and mysteries of Victorian London together.
