Setting

The Only One Left by Riley Sager is set primarily in the 1980s, with flashbacks to the 1920s. The story unfolds in coastal Maine, a region known for its rugged shorelines and picturesque landscapes. This setting provides a stark contrast between the natural beauty of the area and the dark secrets hidden within Hope's End, the cliffside mansion at the center of the narrative.

Hope's End, a decaying mansion perched precariously on a cliff overlooking the sea, serves as the primary location for much of the novel. This Gothic-inspired setting creates an atmosphere of isolation and foreboding, perfectly complementing the mystery surrounding the decades-old Hope family murders. The mansion's deteriorating state mirrors the declining mental and physical condition of its sole inhabitant, Lenora Hope.

Beyond Hope's End, the story briefly touches on other locations, including Kit McDeere's hometown and her childhood home. These settings provide context for Kit's backstory and play a crucial role in the novel's climax. The contrast between the insular world of Hope's End and the wider coastal Maine community underscores the themes of secrets, isolation, and the long-reaching consequences of past actions.
