Georgette Heyer is best known for her numerous Georgian and Regency romance novels, but over the course of her career she also wrote 12 contemporary mystery novels in the style of Agatha Christie. So far I've read about half a dozen of Heyer's romance novels and The Unfinished Clue is my first mystery. This book is decent but nothing special. I can't think of very much I can say about it really. The mystery isn't particularly compelling and the reader isn't given enough information to solve the crime by themselves. There's also a romance subplot in this book which felt tacked-on and rushed. The Unfinished Clue worked better as a comedy-of-manners than it did as a mystery/detective novel. It was a quick, light read and it was quite funny in places. Lola and Francis get some very amusing one-liners. I'd still like to read some more of Heyer's mysteries but I'm not expecting them to match the quality of Heyer's best romance novels.
