Oh my god, what is happening to this series?
The first book of this series was reasonably well plotted. This book is an absolute disaster in search of a plot. Notable highlights:
-Bess and Simon just randomly drive through England in search of one random dude, even though they have, at best, 1.5 clues about where that dude is, that, again at best, narrow it down to an entire county
-Bess and Simon just happen to stop for the night in the same barn where that random dude is hiding
-A completely unrelated OTHER random dude just happens to be in the same area, acting completely insane even though he isn't, apparently solely to confuse the issue (which he knows nothing about).
And so on. This is a string of improbable coincidences masquerading as a plot. The mystery itself is equally ridiculous, and Bess and Simon don't figure out the very obvious key issue until waaaaay too late.
Meanwhile, something terrible has happened to Bess's characterization. She's weirdly timid and newly terrible at detecting, which is weird for someone who is surrounded by murder all the time. At one point, she's walking with someone who has just made it clear that she does have an answer Bess needs, and when that woman indicates that she doesn't want to say anything, Bess is basically like, "WELP, cannot possibly ask a question now! Dang. Sure a pity. But what can one do?" At another point, Diana tells Bess a name, but Bess can barely hear her. Bess thinks it's Evering, and asks everyone she meets about Evering, with no result. Later she gets a letter from Simon, who has spoken to Diana, telling her it's Everard. And Bess ... still thinks it might be Evering, even though she has found no one by that name and couldn't hear what Diana said. She even asks Simon if he's SURE it was Everard. It's like she can't grasp that she heard wrong. (Also, as is typical of the Charles Todd plotting at this point, this entire sequence is completely irrelevant. It's not even a red herring.)
And, sadly, the writing quality of the series has declined dramatically, too. It may actually be an editing problem -- lots of repetitions, lots of mistakes (and I don't just mean the name change of a fairly major character), lots of inconsistencies, but all things a good editor would catch.
And the ongoing flaws of the series are still evident, of course. It continues to be entirely white and straight and colonialist. The authors genuinely seem to believe that people of color and queer people didn't exist before, oh, 1971. Or, more likely, they'd prefer to pretend they didn't. And they seem to want to stand up and cheer for colonialism.
Man. I am going to continue on, but at this point I am not sure my interest in the setting can make up for everything the series has become.
