This book would have easily been a five star for me, but for one major flaw. The time period of this book was 1811, and Lady Althea, and her sister in law Jane, both widows go to London to visit with family. During this time frame no matter if you helped your deceased husband ,with the study of insects, this would not be normal conversation with a gentleman, especially a titled one. A blue stocking, as over educated readers were called ,would still find this beyond the pale, of polite society. Especially with the interest of a dead body, mostly covered by dirt , in the park with a gentleman at your side. Her anger, and critic remarks when he attempted to shield her, were uncalled for, and quite odd. She was trying to get her husband's scientific notes published, and even though she may be more gifted than he, in some ways, he had made a respected name for himself, and she hoped to present additional papers under his name. It was even amazing that a bow street runner, which was considered the police at that time, would give credit that insects could determine time of death, and she a genteel lady would be asked ,to go undercover on a jewelry heist. I actually liked the story, and Jane, and the different men in her life. I liked John, and Charles, both family where she was staying. Norwich though titled, seemed to come to her rescue quite often, though at times she thought him condescending, and his younger brother, who I hope gets a story of his own. There were deaths, explained away as people leaving employment, and jewels missing, and snooping, and a touch of romance, by a surprise gentleman, and a touch of the ridiculous by a rector. What is it with country ministers, and their over zealous expectations.? The ending was near what I had thought, but a bit more ugly, and I was sure that someone else belonged to a type of notorious club, popular during that period. It kept me reading, and guessing until the end. I will be looking for book two in the series. I hope the author keeps her main character more restricted in her comments, because no scientific society would publish under a woman, in that time period, no matter how smart she is, so her educated comments, and abilities can not be on display ,for members, of the Ton, unless it is backhanded in nature.
