From the #1 New York Times bestselling author of Then She Was Gone Lisa Jewell, two women's lives converge in a house containing devastating secrets that refuse to stay buried in this "deliciously dark, devilishly addictive" (Alice Feeney, bestselling author of My Husband's Wife) novel.

Jane Trevally is walking her dogs on her country estate when a small white terrier appears, alone and with no sign of the teenaged girl he’d been staying with nearby. When the teenager is reported missing, Jane offers to return the dog to his registered owner, hours away in London. Arriving at a run-down house called Thornwood in the deepest backwaters of Hampstead, she is immediately on alert—because Jane has a dark history with this house.

The man who answers the door is not the man that Jane remembers from her past. He is cagey, and claims to know nothing about the missing teenage girl. Then, through the window of the house, Jane catches a glimpse of a haunted-looking woman.

Conjuring her memories from twenty-five years ago, Jane knows this unsettling house holds the key—to the missing teenager, to her own traumatic story, and to the dark secrets of the past.
