The Only One Left by Riley Sager: Did She Really Do It? A Spoiler-Free Review

A massive, decaying Victorian mansion perched on a cliff overlooking a stormy ocean.

At seventeen, Lenora Hope
Hung her sister with a rope
Stabbed her father with a knife
Took her mother’s happy life
“It wasn’t me,” Lenora said
But she’s the only one not dead.

If that rhyme doesn’t give you the absolute chills, I don’t know what will! Honestly, I’m still shaking off the goosebumps. Imagine being trapped in a house with the most famous suspected mass murderer in your state, a woman who has been silent for fifty years. That is the exact nightmare fuel Riley Sager hands us in his latest masterpiece, The Only One Left.

I picked this book up as a total goof on a rainy Tuesday, thinking I’d just read a chapter or two before bed. Jokes on me, because I was still turning pages at 3:00 AM with every single light in my house turned on. If you are looking for the perfect, most suspenseful read of the year, stop what you’re doing and get this on your shelf right now.

Stumbling into Hope’s End

The story kicks off with Kit McDeere, a home-health aide who is, let’s just say, having the worst year ever. She’s been suspended from her job following a tragic incident with a previous patient, and she’s desperate for work. When she’s offered a gig at “Hope’s End,” she knows it’s her last chance. But there’s a catch: the patient is Lenora Hope.

Yes, that Lenora Hope.

The house is a crumbling, gothic monstrosity perched on a cliff in Maine, literally sliding into the ocean. It’s the kind of place where you just know the walls are sweating secrets. Kit is terrified, and frankly, I was terrified for her! Would you take a job caring for a woman everyone thinks killed her entire family with an ax? I’m not sure I’m that brave, but Kit’s desperation makes her the perfect lead for this atmospheric journey.

The Silent Witness

Lenora Hope is now in her seventies, paralyzed by a series of strokes and unable to speak. She can only communicate by tapping her left hand: one tap for yes, two for no. But then, things get really interesting. Lenora starts using an old typewriter to tell Kit her side of the story.

“I want to tell you everything,” she types.

My jaw literally hit the floor. This is where the dual timelines start to weave together. We get glimpses of 1929, the night of the massacre, and the tension of 1983 as Kit tries to figure out if she’s helping a victim or a monster. Is Lenora a misunderstood girl who lost everything, or a cold-blooded killer finally looking for one last bit of fame? Riley Sager is the absolute best at keeping you guessing. Every time I thought I had the “whodunnit” figured out, he pulled the rug out from under me.

Why You’ll Be Obsessed With the Gothic Vibes

If you love a book review that focuses on atmosphere, this is the one for you. The house, Hope’s End, is a character all on its own. It’s tilting! One side of the house is significantly lower than the other because the cliff is eroding. Can you imagine the feeling of walking through a mansion where everything is slightly slanted? It creates this constant, nagging sense of vertigo and unease that matches the plot perfectly.

The “Lizzie Borden” vibes are thick here. Sager plays with the idea of public perception and how a catchy rhyme can ruin a person’s life more than a trial ever could. It makes you wonder: if the whole world decided you were a killer, would you eventually start to believe it too?

Kit McDeere: A Relatable (if Troubled) Heroine

Kit is so easy to root for because she’s flawed. She’s escaping her own past while trying to survive Lenora’s. She isn’t some perfect, untouchable detective; she’s a woman trying to keep her head above water. Her initial thoughts about Lenora are just as conflicted as ours. One minute she’s feeling deep empathy for this frail woman, and the next, she’s noticing how sharp Lenora’s eyes are: eyes that have seen things no one should ever see.

I loved the way Sager handled the pacing. It starts as a slow-burn gothic mystery and then suddenly shifts into a high-speed thriller that doesn’t let up. The transitions are seamless, and the simple, direct writing style makes it so easy to devour. You won’t find any academic jargon here; it’s just pure, unadulterated storytelling.

Is It Worth the Hype?

Short answer: YES.
Long answer: This is probably my happiest discovery in the thriller genre this year. It has everything I look for:

A creepy, isolated setting.
A mystery that spans decades.
Characters you can’t quite trust.
A plot that keeps you stumbling from one revelation to the next.

For those of you who follow my blog at Brooke’s Shelf, you know I don’t give out “must-read” labels lightly. But The Only One Left earned it. It’s the happiest I’ve been with a thriller ending in a long time: even if it left me feeling a little bit breathless.

Final Thoughts: Should You Buy or Borrow?

Buy it. You’re going to want to highlight the clues and then go back and read it again once you know the ending. It’s one of those rare books where the “re-read” value is just as high as the first time through.

If you’re a fan of Alice Feeney or if you’ve been following my recent deep dives into book recommendations, you are going to fall head-over-heels for this one. It’s got that same bite and that same “just one more chapter” energy.

Have you read it yet? Did you guess the ending? (Don’t worry, I won’t tell!). Drop a comment or contact me to let me know what you thought. I’m dying to talk about those twists with someone!

Stay spooky, fellow readers!
