I enjoy mysteries and Georgette Heyer's Regency romances, so I thought I'd give one of her mysteries a try. Although I enjoyed reading it (and didn't guess "who done it"), it was not as good as her romance novels. Because of her romance novels, I expected more romance in this mystery. There wasn't much and the relationship developed very quickly. It didn't seem plausible. The Unfinished Clue pales in comparison both to Heyer's romances and to works by the great Agatha Christie.
