In the The Woman in the Window, by A.J. Finn, Anna Fox is in desperate trouble, although she doesn’t seem to know it yet. Separated from her husband and child and mortally afraid to leave her house, she spends too much time drinking Merlot and mixing up her medications. She keeps close tabs on her neighbors, spying on their book club meetings and observing their infidelities. When a new family moves in with a teenage son, Anna takes a special interest, and when the boy visits her with a small gift, she is charmed by his kindness. Her illusion of safety is destroyed one night, however, when she sees what looks like a murder. Not surprisingly, the police don’t believe the disheveled, half-drunk Anna, and as her physical state deteriorates even more, she is not sure what she’s seen. The novel is an outstanding example of the unreliable- narrator thriller (others include The Girl on the Train, Gone Girl, and Shutter Island), filled with genuine frights and heartbreaking secrets.
