Lock Every Door by Riley Sager

Jules Larsen has just lost her job, her boyfriend and her apartment.  With no family and no money she finds herself sleeping on her best friend’s couch.  While searching the want ads she stumbles upon a job opportunity as an apartment sitter at THE most exclusive apartment building in New York City, the Bartholomew.

The job would consist of staying at one of the gorgeous, luxury apartments directly across the street from Central Park, for three months with a stipend of four thousand dollars per month.  Who could possibly pass up this offer?

But Jules soon learns there are some very strange rules attached to the commitment.  No visitors, no nights spent away from the apartment and never bother the other residents. Odd she thinks, but the money would be able to put her back on her feet.

After moving in she discovers a resident is Greta Manville, who wrote a book years ago called Heart of a Dreamer which Jules and her now missing sister would read together. There first introduction does not go as well as she would have imagined. She also discovers she is not the only apartment sitter.

Although being warned the Bartholomew had an eerie, sad history with possible hauntings, Jules spends her first few days becoming acquainted with the complex. She befriends another sitter named Ingrid whose personal problems mimic her own.  When Ingrid does not show up at a planned meeting and Jules finds out she left the Bartholomew without notice during the middle of the night, she becomes alarmed.

While searching for Ingrid, Jules is then plunged into the frightening reality of living in the Bartholomew.  It certainly is not what it seems to be.  She is determined to find out what has happened to her friend and in doing so opens up a Pandora’s Box of greed, privilege and murder, proving the saying, if it’s too good to be true, it probably is. Now Jules must find her way out of the Bartholomew before she too becomes a part of the mysterious Bartholomew’s legacy.

With each turn of the page the anxiety builds and the story begins to unfold into a very sordid and quite unexpected ending.  Very much worth the read!
