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 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.

Riley Sager is the award-winning pseudonym of a former journalist, editor and graphic designer who previously published mysteries under his real name.

Now a full-time author, Riley's first thriller, FINAL GIRLS, became a national and international bestseller and was called "the first great thriller of 2017" by Stephen King. Translation rights have been sold in more than two dozen countries.

Riley's second book, THE LAST TIME I LIED, was published in 2018 and became an instant New York Times bestseller. It was inspired by the classic novel and film "Picnic at Hanging Rock" and one horrible week Riley spent at summer camp when he was ten. A television adaptation is being developed by Amazon Studios.

His latest book, LOCK EVERY DOOR, was an instant New York Times, Publishers Weekly and USA Today bestseller. A television adaptation is being developed by Paramount TV and Anonymous Content.

A native of Pennsylvania, Riley now lives in Princeton, New Jersey. When he's not writing, he enjoys reading, cooking and going to the movies as much as possible. His favorite film is "Rear Window." Or maybe "Jaws." But probably, if he's being honest, "Mary Poppins."
