The Ghosts of Thorwald Place

Trust No One. Especially your neighbors.
Rachel Drake is on the run from the man who killed her husband. She never leaves her safe haven in an anonymous doorman building, until one night a phone call sends her running. On her way to the garage, she is murdered in the elevator. But her story doesn't end there.
She finds herself in the afterlife, tethered to her death spot, her reach tied to the adjacent apartments. As she rides the elevator up and down, the lives of the residents intertwine. Every one of them has a dark secret. An aging trophy wife whose husband strays. A surgeon guarding a locked room. A TV medium who may be a fraud. An ordinary man with a mysterious hobby.
Compelled to spend eternity observing her neighbors, she realizes that any one of them could be her killer.
And then, her best friend shows up to investigate her murder.
