Miss Scarlet and the Duke plot
When Eliza's father dies, he leaves her penniless at a time when marriage is her only option for financial security. But the stubborn Eliza is determined to find another way. Fortunately, she has an asset up her sleeve - her father's company - a private detective agency. Eliza knows all the tricks of the trade, but as a dignified 19th-century lady, she was never allowed to put them into practice. To operate in this man's world, she needs a partner. She finds it in Scotland Yard Inspector William Wellington, who is also known as "The Duke".
