A sleuthing garage sale maven suspects foul play when her friend dies in an old house with a cursed reputation. Even though police evidence - and even webcam footage of the death – point to natural causes – this mysterious death in a cursed” home poised for multi-million dollar sale seems too coincidental. Putting her keen instincts to work, she examines a few key suspects. As she digs into this deadly mystery, she uncovers clues that bring her closer to the truth, and even put her own life in danger.
Unfortunately the movie Garage Sale Mystery: The Deadly Room is not yet available on HBO Max.
