Shared Walls

What if the wall between you and your neighbor isn't a boundary, but a channel? Freelance sound engineer Drew Kerr needs a fresh start after a career-ending disaster. When she finds an affordable, beautifully renovated brownstone in Philadelphia, it feels like the perfect escape. The acoustics are flawless, and her new neighbor, Luka, is charming, quiet, and impeccably helpful. But Drew's highly trained ears pick up what others miss. It starts with a faint 60-hertz hum every night at 2 AM. Then, her ambient microphones capture a muffled voice dictating a chilling ledger of names and dollar amounts through the plaster—and her name is on the list. As Drew investigates the historic building, she uncovers a terrifying reality. The brownstone is riddled with hidden cameras, secret passages, and the stolen identities of women who lived there before her. Luka isn't just a friendly neighbor; he's the architect of a deadly insurance fraud operation that targets isolated women. And according to his meticulous timeline, Drew's life has an expiration date that is rapidly approaching. Trapped in a home engineered to watch her every move, Drew must use her audio expertise to outsmart a methodical predator. With the clock ticking down to the day her life insurance policy pays out, she must turn the building's surveillance against its creator before she becomes just another profitable casualty.
