From Jane Fallon comes a sharp and addictive psychological drama about obsession, jealousy, and the secrets people keep behind closed doors.

Tamsin and her husband have the perfect life—successful careers, a beautiful home, and a relationship that seems unshakable.

Until Tamsin becomes convinced that he’s having an affair.

Determined to uncover the truth, she begins watching the woman she suspects—following her, learning her routines, and slowly inserting herself into her life. What starts as suspicion turns into a calculated plan, as Tamsin befriends the very woman she believes is destroying her marriage.

But the deeper she gets, the more complicated things become.

Because nothing is quite as it seems—and the truth may be far more shocking than Tamsin ever expected.

Clever, tense, and full of twists, this story explores trust, manipulation, and how far someone will go when pushed to the edge.
