Lock every door

Author's name: Riley Sager

"Looking for a gripping novel that will keep you up well past midnight? Look no further than Lock Every Door. It has everything you need. By Riley Sager." - Stephen King. No visitors. No overnight stays away from the apartment. No disturbing other residents. The inhabitants of Bartholomew are all rich or famous, or both. These are the only rules and laws of this job, and those that Jules Larson, the new apartment sitter at Bartholomew, one of Manhattan's most famous and mysterious buildings, must follow. Lately, Jules has been completely heartbroken and depressed, so she happily accepts her new surroundings and the terms, willing to leave her past life behind for this job. As Jules gets to know the residents and staff of Bartholomew, she finds herself drawn to her colleague Ingrid, the other apartment's caretaker, who comfortingly reminds her of the sister she lost eight years ago. When Ingrid admits that Bartholomew isn't what it seems and that the dark history hidden beneath its gleaming facade is starting to frighten her, Jules dismisses it as a harmless ghost story... until the next day, when Ingrid disappears. Searching for the truth about Ingrid's disappearance, Jules delves into Bartholomew's sordid past and the secrets kept within its walls. What she uncovers puts Jules against the clock as there's a frantic race to unmask a killer, uncover the building's hidden past, and escape Bartholomew before her temporary situation becomes permanent.
