Slow and overwrought, I struggled to get through this book. While I've enjoyed many other mysteries set in Georgian, Regency, Victorian, and other time periods, I kept putting this one down. It wasn't at all the fast paced page turner promised by the blurbs and reviews. The premise doesn't quite make sense. And despite the fact that it takes place in 1811, Sebastian, the protagonist, must have had a very speedy form of transport to zip him around London so quickly. Not recommended.
