A young woman runs through the storm, gasping for breath. On her palm, carved into the flesh, are the words: “Pr has returned.” She doesn’t know what day of the week it is, or what month. She thinks her mother is alive, though her mother died by suicide long ago. Lucy Enébel, a police lieutenant, tries to figure out who this woman is, what the words carved into her skin mean, and where the marks of a rope are on her wrists. The key to unraveling the mystery must be sought in the heroine’s memory—but her memories vanish faster than traces in the sand beneath the surf…
Four minutes—that’s exactly how much time any memory is given. Then everything is erased.
