Twins in mysteries have become cliche, along with the various possibilities of one twin impersonating another, whether that twin is a victim or a criminal. Still, even given that and a few more possibilities that I considered, I did not expect this resolution to the story.
I enjoyed reading more of these characters - Monk, Hester, Rathbone. Some of the plot felt a little long, but it kept me interested.
I know some readers might get frustrated with that society's views on women, but to me, it's more like we know a secret that society didn't: women can be highly intelligent contributors. And they manage to contribute despite the society around them. Books like that don't bother me because, in part, it was the historical era, and in part, because the women do well, even despite the social handicap. It's like watching someone win a race after having to start a pace or two behind everyone else. It only goes to show their racing excellence in that the worse start did not really stop them.
One reviewer didn't like the false allegation in this book, thinking that it cast doubt on all the real allegations out there. Statistically speaking, the allegations are not likely to be false and should be treated seriously. Still, false allegations have existed in reality, which is why each case has to be considered in light of evidence. People are not just guilty or innocent because we want them to be. While I would hope that any daughters of mine would be listened to in reporting such harassment, I would also hope that any one accusing them of anything would not be entertained without evidence.
I have reservations about the author herself, Anne Perry, who actually did commit murder as a young teen. I hate for her to capitalize on the experience in her books, but sometimes her themes are more of mercy, pity, reconciliation, etc. Usually, I limit my reading of her books to just library books, where there is less royalties, because less copies have been bought. Or, I limit it to second-hand shops.
