Death in the Dark Walk by Deryn Lake
The first in a series of murder mysteries set in 18th century London, also featuring John Fielding. Very similar in many ways to the Blind Justice series, also featuring a young assistant helping Sir John Fielding solve murders. In this case, Fielding is very much a secondary character, only appearing in a few scenes, so the devo factor us quite low. On the other hand, the quality of the writing is much better than in the other series. The historical details are vivid and lively, clearly well researched. The main characters seem a bit naive and prudish for living in such bawdy times. It bothers me when historical novels conflate the morality of the 19th and 18th centuries, which were quite different. But overall, it's an enjoyable read.
