The Only One Left by Riley Sager Summary: Unraveling the Gothic Mystery
A Twisted Gothic Mystery That Defies Every Expectation
Something is wrong with Hope’s End.
The Gilded Age mansion doesn’t just loom over the Maine coastline — it tilts toward the ocean, sinking inch by inch into the Atlantic, pulling decades of dark secrets with it.
Inside, a woman who has not spoken in fifty-four years is about to type the truth.
One keystroke at a time.
Riley Sager’s The Only One Left drops readers into 1983, where caregiver Kit McDeere arrives at this decaying cliffside estate.
Her patient is Lenora Hope — the sole survivor of a 1929 family massacre that left her parents and sister dead. Everyone knows the nursery rhyme: “Lenora Hope / Hung her sister with a rope.”
Riley Sager is the pseudonym of Todd Ritter, a former journalist and editor who pivoted to fiction with his breakout debut Final Girls in 2017.
He has since published seven consecutive New York Times bestselling thrillers, earning a reputation for twist-laden plots, atmospheric settings, and protagonists haunted by their pasts.

The Only One Left Summary: A Full Deep Dive (SPOILERS)
Warning: Complete plot spoilers follow. This section recounts the story from beginning to end.
Kit McDeere arrives at Hope’s End in 1983 carrying her own burden. Six months earlier, she was cleared of wrongdoing in her mother’s death, but the suspicion never lifted. Her father, Patrick, barely looks at her.
The mansion is a character unto itself.
Three stories tall, perched on an eroding cliff fifty feet above the Atlantic, it tilts visibly toward the ocean. The carpets still bear bloodstains from 1929. The service stairs are narrow and hidden. The rhythmic crash of waves is constant.
Kit’s patient is seventy-one-year-old Lenora Hope.
A series of strokes has left her mute and paralyzed — except for her left hand. The household includes the stern housekeeper Mrs. Baker, the longtime cook Archie, a maid named Jessie, and a groundskeeper named Carter.
On Kit’s first night, Lenora gestures toward a typewriter.
She wants to tell her story.
One keystroke at a time, a parallel narrative emerges from 1929. It follows seventeen-year-old Lenora on the night of her birthday. Her father Winston is a tyrant.
Her mother Evangeline self-medicates with laudanum. Her younger sister Virginia is seventeen months her junior — beautiful, impulsive, and their father’s favorite.
Into this volatile household comes Ricky, the new groundskeeper. He is handsome and working-class — forbidden fruit in the rigid social order of the Cliffs.
A romance blossoms, but not with Lenora.
Meanwhile, Kit’s present-day investigation intensifies. She hears strange noises at night. She finds belongings left behind by Mary Milton, the previous nurse who supposedly quit. Then she discovers Mary’s body buried in the sand at the base of the cliff.
Detective Vick rules it a suicide. Kit knows better.
The typed narrative reveals that Virginia — not Lenora — was Ricky’s lover. Virginia became pregnant. On the night of October 28, 1929, everything shattered. The massacre was not a calculated killing but a chaotic eruption of violence. Winston attacked first.
Evangeline died in the struggle. Ricky was there. When it was over, three people lay dead, and Virginia’s baby was taken from her.
Kit pieces together the truth through investigation and confrontation.
The paralyzed patient is Virginia. The real Lenora — the one the world believes died six months after the murders — is alive and has been posing as Mrs. Baker, the housekeeper.
Lenora forced Virginia to swap identities so she could escape the public’s hatred and inherit the family fortune while Virginia bore the punishment.
Then comes the most devastating revelation. Kit learns that “Ricky” — the groundskeeper from 1929, Virginia’s lover, the father of her child — is actually Patrick McDeere. Her own father.
He was a teenager working at Hope’s End under a false name. Mary Milton discovered this truth and approached him for a blood test. He killed her to protect his secret.
Patrick returns to Hope’s End one final time. He intends to kill Virginia, the last living witness. A violent confrontation erupts.
The unstable cliff, eroded by decades of relentless waves, finally gives way. Patrick and the real Lenora choose to stay inside. The mansion slides into the Atlantic, taking them and its bloodstained history with it.
Kit and Virginia escape. Two months later, Virginia leaves a note. She has been faking the full extent of her paralysis for more than five decades.
She has reunited with her granddaughter — Jessie, the maid, who was undercover all along. The two have fled to Paris.
An epilogue reveals that Virginia lived to age 101.
She traveled the world and became a media sensation after publishing a memoir about what the press called “the greatest hoax of the century.”
