Determined to help, Audrey Rose and Thomas begin their investigations, only to find themselves facing a serial killer unlike any they've encountered before. Identifying him is one thing, but capturing him

and getting dangerously lost in the infamous Murder Hotel he constructed as a terrifying torture device

is another.
Will Audrey Rose and Thomas see their last mystery to the end

together and in love

or will their fortunes finally run out when their most depraved adversary makes one final, devastating kill?
