No visitors. No nights spent away from the apartment. No disturbing the other residents, all of whom are rich or famous or both. These are the only rules for Jules Larsen's new job as an apartment sitter at the Bartholomew, one of Manhattan's most high-profile and mysterious buildings. Recently heartbroken and just plain broke, Jules is taken in by the splendor of her surroundings and accepts the terms, ready to leave her past life behind.

As she gets to know the residents and staff of the Bartholomew, Jules finds herself drawn to fellow apartment sitter Ingrid, who comfortingly, disturbingly reminds her of the sister she lost eight years ago. When Ingrid confides that the Bartholomew is not what it seems and the dark history hidden beneath its gleaming facade is starting to frighten her, Jules brushes it off as a harmless ghost story ... until the next day, when Ingrid disappears.

Searching for the truth about Ingrid's disappearance, Jules digs deeper into the Bartholomew's dark past and into the secrets kept within its walls. Her discovery that Ingrid is not the first apartment sitter to go missing at the Bartholomew pits Jules against the clock as she races to unmask a killer, expose the building's hidden past, and escape the Bartholomew before her temporary status becomes permanent.

Lock Every Door


Light slices the darkness, jerking me awake.

My right eye—someone’s prying it open. Latex-gloved fingers part the lids, yanking on them like they’re stubborn window shades.

There’s more light now. Harsh. Painfully bright. A penlight, aimed at my pupil.

The same is done to my left eye. Pry. Part. Light.

The fingers release my lids, and I’m plunged back into darkness.

Someone speaks. A man with a gentle voice. “Can you hear me?”

I open my mouth, and hot pain circles my jaw. Stray bolts of it jab my neck and cheek.


My voice is a rasp. My throat is parched. So are my lips, save for a single slick spot of wet warmth with a metallic taste.

“Am I bleeding?”

“You are,” says the same voice as before. “Just a little. Could have been worse.”

“A lot worse,” another voice says.

“Where am I?”

The first voice answers. “A hospital, honey. We’re taking you for some tests. We need to see how banged up you really are.”

“It dawns on me that I’m in motion. I can hear the hum of wheels on tile and feel the slight wobble of a gurney I just now realize I’m flat-backed upon. Until now, I had thought I was floating. I try to move but can’t. My arms and legs are strapped down. Something is pythoned around my neck, holding my head in place.

Others are with me. Three that I know of. The two voices, and someone else pushing the gurney. Warm huffs of breath brush my earlobe.

Why I love it

Let’s twist again, like we did last summer: Riley Sager is back with a dark, suspenseful novel about a house-sitting job from hell! It’s the must-read summer thriller that will have your little gray cells twerking up a storm!

Jules Larsen is having bad luck. Suddenly jobless and homeless, she’s over the moon when she’s hired to be an apartment sitter at the Bartholomew, a famously mysterious and prestigious NYC apartment building. One thousand dollars a week to live in a huge, fancy apartment? It sounds too good to be true! Spoiler: That’s because it is. Shortly after her arrival, she hears strange noises, and learns some upsetting stories about the building’s past. Ruh-roh, Shaggy! And just when Jules discovers that the last woman to stay in the apartment disappeared under mysterious circumstances, another sitter goes missing, leaving Jules to wonder if she’ll make it out of the Bartholomew alive.

Look, I’ve read enough mysteries to know that there are always twists, and that you can’t trust any of the characters. What was fun was trying to figure out just who was telling the truth. Sager does an excellent job of bringing the creep to an old-school scary mystery that will keep you turning pages—and checking your locks.

    Another twisty Sager novel you can’t not enjoy! Absolutely loved where the book takes you, was a little surprised by the outcome, but overall good plot. A little slow going till about halfway ⭐️⭐️⭐️⭐️

    So loved this book. Not surprising, as I love every one I’ve read by Riley. When I’m staying up until 2a after a long day simply to finish, it must be good! Twists, turns, switchbacks…🔀🌟🌟🌟🌟🌟
