The Tiara on the Terrace

Just as fun as the first book The Wig in the Window. Grace and Sophie and their friend Trista are determined to solve the mystery of who killed Jim Steptoe. The police are saying it's an accident but they know it must be murder. Sophie and Grace are still friends bur of course there is jealousy when Sophie thinks Grace is starting to outgrow the fun they've always had together. So not only do they have to try and solve the mystery Sophie worries about her friendship with Grace. So there is that slight realistic fiction aspect of the possibility of your friend drifting away from you.
Fun book and fun mystery. While the mystery is a bit over the top for adults I think middle grade kids should like it. Even some adults who can appreciate middle grade fiction like I do should find it a fun read. I know I did.
