This was really well written; just enough frustration to sympathise with older and confused Maud and her daughter who is her primary carer, without getting too repetitive that it becomes annoying.
I’ve read other reviews that call this a psychological thriller in the vein of Gone Girl etc. but it really isn’t. That’s neither a good or bad thing; I like those kinds of thrillers and I also liked this, but they are completely different. I wouldn’t call this a thriller as such. It has mystery and intrigue which is why you keep reading, but honestly, it’s so nicely written that I would probably have read on regardless.
