The Key Was Under The Mat. Away From Home, #9

"The safest lock is the one your family installed."Sarah, a professional home stager, knows exactly how to make a house look like a home. She knows the friction of a real family's life, and she knows how to manufacture the illusion of it. But when her husband, Dean, surprises her and their seven-year-old daughter, Ruby, with a week-long getaway to a cedar-sided cottage on Lake Michigan, Sarah's professional eye uncovers a terrifying reality.
The brass key left under the mat doesn't fit their rental-it opens the identical cottage next door. Inside, she finds a chilling, perfect replica of her own life: her clothes hung in the closet, her preferred groceries in the fridge, and a meticulously repaired stuffed animal belonging to her daughter propped on the bed. Someone has been painstakingly staging her existence four hundred miles away from home.
As Sarah investigates the fake house, she unravels a year-long conspiracy orchestrated by the man she thought she knew. Dean hasn't just been renting the cottage; he's been draining their savings, hiding $87, 400 in accounts belonging to his mother, Constance-a woman Dean claimed had died of cancer seven years ago. With a forged goodbye letter written in her exact handwriting and a newly tripled $750, 000 life insurance policy, Sarah realizes this isn't a stalker's obsession.
It's an exit strategy. Her husband isn't planning a divorce; he's orchestrating her voluntary disappearance. Trapped in a remote lakeside town, Sarah must outwit a man who has anticipated her every move and manipulated the people around them. But Dean made one critical mistake: he underestimated their quiet, observant daughter, who swapped the keys and set the discovery in motion. Now, Sarah must beat her husband at his own game before his terrifying deadline arrives, staging the most important reveal of her life before she becomes the victim of his perfect narrative.
