I always enjoy psychological books, where nothing is as it seems at the beginning and this didn’t disappoint. As Cat delves deeper into her husband’s life things are much worse than they appeared initially, the catalyst of their problems being the arrival of a previously unknown love-child. Who is the one orchestrating Cat’s decline? The child? Her husband? Or herself? The spectre of mental health overshadows the whole novel and is a really interesting look at how the stigma of it never really goes away. Powerfully written.
