A Lady's Guide to Mischief & Mayhem

 A Lady's Guide to Mischief & Mayhem (2020) by Manda Collins

England 1865: Lady Katherine Bascomb is a rather unconventional Victorian woman. She not only owns a newspaper, thanks to her husband's early demise, but she also (gasp!) writes columns. When a serial killer who has been dubbed the "Commandments Killer" by the press goes uncaptured by Scotland Yard after four murders, she and her newly found friend Caroline "Caro" Hardcastle decide to cowrite a column to investigate the latest murder. A column they plan to develop into practical advice for ladies about how to stay informed and protect themselves. They realize that not only has the killer been leaving cards with one of the Ten Commandments on the bodies, but it can be proved that each victim was "guilty" of breaking that particular commandment. Their investigation finds a young barmaid whom the Yard managed to miss interviewing and who may have seen the killer. The ladies write their article and the Yard immediately finds a man matching the description and arrests him....

Except Inspector Andrew Eversham, who was relieved of duty on the case because his superior was upset that mere reporters found what he couldn't, doesn't believe the right man is behind bars. And neither does Lady Bascombe, for that matter. When they meet (in the fracas that follows the new inspectors announcement to the press), he's understandable upset with her over what he regards as interference. She points out to him that it wouldn't have been necessary if he'd done his job. They part on less than friendly terms.

Lady Bascombe is invited to her friend Lord Valentine's country estate for house party--she plans on enlisting his aid to get the Yard to investigate the murders more thoroughly (knowing that the men in charge will listen to a titled man before listening to a woman's "fancies" about justice). She doesn't expect irrefutable proof that the wrong man has been jailed to appear on a country walk near the estate. But that's just what happens and Katherine is the one to find it. Another murder and another card with a commandement. And guess who the Yard sends to investigate? Inspector Eversham. Those two are sure to lock horns....unless they realize that they're on the same side and actually....the other person really isn't that annoying. In fact, they're kind of attractive....

First observation: If there really had been as many progressive/headstrong women determined to live outside the conventions in the 18th and 19th centuries as historical mystery writers have strewn about, then there would have been a social revolution much sooner with more far-reaching results. Especially, if there had also been as many men who were so willing to support these women. I mean, they would have been tripping over each other all the time. 

Now that I've gotten that out of the way....This is a fun, nicely plotted mystery. Did I spot the culprit? Yes (Qualified, yes, that is. Can't explain or that would be a spoiler.). Did I completely figure it out? No. And that's satisfying. I figured out just enough to be able to pat myself on the back and enough was left for the author to explain that I got a bit of surprise. I like Katherine and Andrew together and Caro and Lord Valentine are good supporting characters. It's hard to believe that a mystery featuring serial killings could be cozy and done with a light touch, but Collins achieves this. There are more in this series and I've already put the next one on hold at the library. ★★★ and 1/2

First line: If Sir Horace did not desist from his asinine talk about what constituted appropriate conversation for a lady, she would do one of them an injury, thought Lady Katherine Bascomb, hiding her scowl behind her fan.

Last line: Eversham was sure he was up to the challenge.
