Anna Fox, agoraphobic, lives alone in her New York apartment. She spends her days drinking too much, watching old movies and spying on her neighbours. When the Russells, mother, father and son move into the house next door, she sees something she shouldn't. From there, what is real, what is imagined? Who is in danger and who is in control? Nothing is what it seems. Twisty and powerful, ingenious and moving, this is a smart sophisticated novel of psychological suspense. At last, a fast-paced, taut story with not one bit of self-indulgent or superfluous language.
