"Autumn has arrived and the fourth graders at Arthimos Elementary couldn't be more excited for the Fall Festival! But when the tickets go missing, the pie eating contest is sabotoged, and a suspiciously humongous pumpkin shows up, will anyone be able to save the day and catch the culprit? The school's best (and only) investigators are on the case, The Prime Detectives--Abby 'the Abacus' Feldstein, Cameron 'Cam' McGill, and Gabriel 'Gabe' Kim. Using arithmetic, geometry, and logic, the Prime Detectives will stop at nothing to figure out who did what, when, and why!"--Amazon.

Azaleah's big sister, Nia, has been cast as Willa Wonka in the school musical, and the entire Lane family is looking forward to the show. Azaleah has even helped plan a surprise dinner party for Nia at Avec Amour, Mama's restaurant. But then the real drama starts. At the first rehearsal, all sorts of things go wrong: missing batteries, sets falling over, props misplaced . . . It's so many things, in fact, that Azaleah suspects "foul play." And when the special effects on Nia's costume don't work at dress rehearsal, Nia is a nervous wreck. To top it all off, the high school journalism class is covering the performance for the school blog, and the director doesn't have time to replace Nia's costume. Nia has to wear it without the special effects. Azaleah becomes determined to make sure the musical isn't ruined for Nia. Azaleah has to get to the bottom of the mysterious rehearsal troubles, and finish party preparations, before the curtain goes up.

Azaleah's older sister Nia is going to be the star of the school musical but things keep going wrong at the rehearsals (missing batteries, disappearing props, microphones that suddenly do not work); Mr. Guidi, the director, blames the ghost of Thespis, but Azaleah suspects that somebody is actually sabotaging the play--and she is determined to use her detective skills to uncover the culprit, and set things right so the play will be a complete success for her stressed-out sister.
