I have recently begun Behind Her Eyes, by Sarah Pinborough. This is a psychological suspense that has apparently come to Netflix, though I haven’t watched it. Pinborough weaves a complex web between three characters, David, his wife Adele, and his secretary Louise. There is definitely something wrong in David and Adele’s marriage, but Pinborough only hints at what is going on, and from the various reviews and descriptions of the plot, I can only get that what you think is going on is definitely not what’s really going on behind the scenes here.
