So I HATE Christina Balantyne, which is fine, because she dies at the end of this one. She popped up in an earlier book when she was totally getting banged by the smug, oily, pretentious footman Max, and her mom Augusta had Max thrown out, and I'm 95% sure Christina was pretty sure she was pregnant (by Max) and so her mom made sure that Alan Ross (who had lost his beloved Helena, who actually sounds like a neat girl except her only appearance in the series was as a pregnant skeleton) married Christina. (There was no baby so either I'm misremembering or she miscarried or had an abortion.) But Alan's too good for that bitch. The other two members of the family are General Balantyne, who is nursing a HUGE crush on Charlotte and very nearly compromises himself in this one by telling her his feelings (she admits that she's married first, and it's all super awkward because General Balantyne really isn't a bad guy) and the son, Brandon, who married Jemima the governess and seems super happy with her. Also, Christina's a bitch?
Anyway, this book kicks off with the discovery of a stabbed and castrated corpse in a bad part of town. Max was also killed that way (hooray, 'cause he was an asshole) and it turns out he had started a "high class" brothel where bored society ladies could come get banged by society guys and hilarity, whatevs. Anyway, a doctor gets killed (he was botching abortions and thus making the women in question unable to have children and maybe making them look awful in the lady region as well? I just had that impression) and this other asshole, who was discovered on the steps of a "for men only and we mean it, only dicks allowed" brothel, owned a row of gin mills and was profiting from the poor, and a math teacher who was a pedophile (he was just clever enough not to molest the students he was tutoring). I think that was it. Anyway, Max died because Christina paid two female brothel owners to do it, and then to kill her lover because why not, and then they were like "Hell yeah let's kill that asshole doctor too, and that pedophile for good measure," and anyway Thomas gets stabbed and survives (he has to, his name is in the name of the series) and Charlotte wears fancy dresses (which I love) and at the end of it Christina gets shot, and good riddance! Go find someone awesome, Alan!
