When Ryli and Aunt Shirley learn not only are they being nominated as a duo for Private Investigator of the Year, but the nominees are being treated to a weekend of fun before the awards ceremony, they are ecstatic. Until Ryli learns the weekend of fun consists of a scavenger hunt...at a haunted house! Add to the mix Ryli is being blackmailed by Willa Trindle, her arch-nemesis, to attend the hunt, and Ryli yearns to beg off. When the three women arrive at the Gothic mansion, Graves Manor, things go from bad to worse when they are told they must all room together. Just when Ryli thinks she's at her breaking point...real terror begins! The clues that are supposed to be easy and fun have turned menacing and deadly! When people start getting hurt, and one person winds up dead, Ryli, Aunt Shirley, and Willa must race to find the killer before they are next in line! Not too hard for Ryli and Aunt Shirley...if only Willa would have left her catsuit and high-heeled boots at home! Can the dynamic duo--Ryli and Aunt Shirley--come through again? Or will this be the last case the girls solve together?
