Catching a killer is dangerous--especially if he lives next door From the hugely talented author of The Kind Worth Killing comes an exquisitely chilling tale of a young suburban wife with a history of psychological instability whose fears about her new neighbor could lead them both to murder . . . Hen and her husband Lloyd have settled into a quiet life in a new house outside of Boston, Massachusetts. Hen (short for Henrietta) is an illustrator and works out of a studio nearby, and has found the right meds to control her bipolar disorder. Finally, she´s found some stability and peace. But when they meet the neighbors next door, that calm begins to erode as she spots a familiar object displayed on the husband´s office shelf. The sports trophy looks exactly like one that went missing from the home of a young man who was killed two years ago. Hen knows because she´s long had a fascination with this unsolved murder--an obsession she doesn´t talk about anymore, but can´t fully shake either. Could her neighbor, Matthew, be a killer? Or is this the beginning of another psychotic episode like the one she suffered back in college, when she became so consumed with proving a fellow student guilty that she ended up hurting a classmate? The more Hen observes Matthew, the more she suspects he´s planning something truly terrifying. Yet no one will believe her. Then one night, when she comes face to face with Matthew in a dark parking lot, she realizes that he knows she´s been watching him, that she´s really on to him. And that this is the beginning of a horrifying nightmare she may not live to escape. . .
