1 New York Times Bestseller Soon to be a major motion picture in October 2019 starring Amy Adams, Julianne Moore, and Gary Oldman "Astounding. Thrilling. Lovely and amazing.... Finn has created a noir for the new millennium, packed with mesmerizing characters, stunning twists, beautiful writing and a narrator with whom I'd love to split a bottle of pinot. Maybe two bottles--I've got a lot of questions for her."-- Gillian Flynn, #1 New York Times bestselling author For readers of Gillian Flynn and Tana French comes one of the decade's most anticipated debuts, published in forty-one languages around the world: a twisty, powerful Hitchcockian thriller about an agoraphobic woman who believes she witnessed a crime in a neighboring house. Anna Fox lives alone--a recluse in her New York City home, unable to venture outside. She spends her days drinking wine (maybe too much), watching old movies, recalling happier times . . . and spying on her neighbors. Then the Russells move into the house across the way: a father, a mother, their teenage son. The perfect family. But when Anna, gazing out her window one night, sees something she shouldn't, her world begins to crumble--and its shocking secrets are laid bare. What is real? What is imagined? Who is in danger? Who is in control? No one - and nothing - is what it seems in this riveting thriller that gripped the world.
