A Chilling Cold Case Whodunit Packed with Twists, Red Herrings, and Shocking Revelations

"I'm working on the greatest mystery ever."

Those were the haunting final words from legendary mystery novelist Mercedes Livingston—before she vanished without a trace from the fog-shrouded halls of Hill House Hotel. Spoken to a wide-eyed seven-year-old Chris Matheson, they ignited an unsolved disappearance that baffled detectives for decades, spawning endless theories, false leads, and a legacy of pulse-pounding suspense.

Now, a retired detective, grown-up Chris Matheson is jolted back into the fray by a cryptic autographed novel and a mysterious letter—forensic clues that point straight to a cunning killer lurking in the shadows. Teaming up with an elite squad of fellow retired law enforcement specialists working under the cover of a book club, Chris reignites this infamous cold case, peeling back layers of deception in a suspenseful investigation riddled with twists and red herrings.

But as they unearth buried secrets from that fateful night at Hill House Hotel, the stakes skyrocket. Was Mercedes's "greatest mystery" a fictional masterpiece...or a real-life setup to commit the perfect murder? One wrong move, and Chris could become the killer's next victim.

Watch out—the clues are scorching hot, and the truth is deadlier than fiction!
