From the award-winning Spanish writer Javier Marías comes an extraordinary new book that has been a literary sensation around the world: an immersive, provocative novel propelled by a seemingly random murder that we come to understand—or do we?—through one woman’s ever-unfurling imagination and infatuations. At the Madrid café where she stops for breakfast each day before work, María Dolz finds herself drawn to a couple who is also there every morning. Though she can hardly explain it, observing what she imagines to be their “unblemished” life lifts her out of the doldrums of her own existence. But what begins as mere observation turns into an increasingly complicated entanglement when the man is fatally stabbed in the street.
