I had much higher hopes for this and I honestly feel like I could've rated this a lot higher if Charlotte had ever fucking actually apologized to Sylvie. She barged her way back into her life as though she had some right to it, as though Sylvie had somehow wronged her by getting away from their shitty living situation by falling in love (or even, as Charlotte theorizes, not falling in love and just finding a man to get her out) when that is absolutely something Charlotte should be happy Sylvie has managed to do, no matter the reality of that. And instead acts as though she's been betrayed (um, no?) and then ruins her sister's life and then nEVER APOLOGIZES FOR IT. I always root for the gays, always, except for this time when I was like: fuck you and the horse you rode in on for lying to your sister, gaslighting her with a spirit, destroying her marriage, and then acting like you are somehow the victim in this scenario??? Charlotte could've just asked her sister for help, she could've told Sylvie the same story Florence told her and, especially if she had come to her before anything happened between them (because Sylvie has every reason to doubt Charlotte's perception of things once she's romantically involved), she might've helped without the lie. Hard to say, she had a lot to lose but she also clearly cares for her sister and isn't without empathy, but we'll never know what she would've done because Charlotte didn't have enough respect for her sister to give her the opportunity to be her best self.
Sibling relationships are generally more forgiving than others - you can get away with a lot of shit when it comes to family that you cannot with friends, but not without admitting you're in the wrong and Charlotte never did that and so I know I, as the reader, didn't forgive her. Sure, she tried to make it right(ish - because she had nothing really to lose, she definitely wasn't coming back to France regardless so not being able to is no real loss lbr) at the very, very, very end but she still never said or acted like she did anything wrong. Which she definitely fucking did and it made me hate her tbqh. All the guilt she felt (and that she definitely SHOULD feel), she brushed off and then tried to turn back around on Sylvie for not being supportive of her and Florence. Which.... OF COURSE SHE ISN'T, you just did this exact same thing on the last case she worked with you, which is why it was the last case she worked with you because it all blew up in your face and you almost went to jail. Like..... what the fuck is wrong with Charlotte that she somehow cannot understand any of this? Oh boy, I did not like her. And I didn't like Florence because she got in the middle of shit and then tried to blackmail Sylvie, immediately, rather than apologize and explain things when they were caught lying to her. Like, what absolute pieces of shit trying to tell me this woman (Sylvie) is selfish when they used her as a pawn, threatened her when she figured out their ruse, and then somehow she takes the fall for them when Charlotte and Florence murder a dude. And I'm supposed to be happy about that???????
Sure, their cause was morally right and good but Charlotte's really gonna call Sylvie selfish when she did not think about that woman for one goddamned moment, did not care about the consequences of involving her, and then let her take the fall for her crimes. Wow. Wooooooow.
