While taking a moonlight stroll at a house party, she stumbles upon a notorious rake spying on French traitors. Afterward, she offers her services to the Home Office to help catch an English turncoat, turning her dull life as a spinster into one of adventure with plenty of intrigues. What she doesn’t expect is to fall in love with the rake, Owen Sheffield, the Earl of Blackmore.
