An assured touch for whimsical turns and a lively, amusing handling of historical romance for the story of Elinor, who arrives at the wrong house for a job. She is unavoidably married to a shocking fellow on his deathbed, and is led into involuntary participation in the ambition of the dead man's uncle, Lord Carlyon, to penetrate the treasonable activities of Bonaparte agents. All of a pucker, Elinor finds her enforced widowhood dominated by Carlyon, whose monstrous coceit and doubtful behaviour keep her enraged. She also finds that strange visitors to her new estate are murdered, that she is herself in danger, that Carlyon's brothers and sisters combine to placate her. She is at last persuaded that the day is saved for England and that Carlyon's conits are chivalrous and her widowhood will end in a real wedding. Mistakes done to a turn, in Georgette Heyer's skilled manner.
