Hen and her husband Lloyd have settled into a quiet life in a suburban house outside of Boston. Hen is an illustrator and has set up shop in a nearby studio, where she can forget the world and focus on her craft. After a few exhausting years of trial and error she has found the right meds to control her bipolar disorder, finally she has some stability and peace to do what she loves- create. But when they meet the couple next-door that calm begins to erode when she spots a familiar object in the husband‘s office, it looks exactly like something connected to a killing that happened years ago, one of very few pieces of evidence in a disturbing and baffling case. Could her neighbor be connected to the killing? Hen recognizes it instantly because she’s had fascination with this unsolved murder and obsession. She doesn’t talk about anymore, but can’t fully shake either. The more Hen observes Matthew, the more she suspects he’s planning something truly terrifying.
