Part One: Question Your Desires; Chapter One: Rachel, Saturday

In this sixth novel of the Terribly Acronymed Detective Club series, all the world's a stage, and Rachel, Al, Lauren, Joe and Sunny find themselves playing parts scripted for them deep in the past, forced into acting when all they want is a quiet, content summer after an eventful fall and winter that saw many of their number injured and out of commission. A new tragedy, the passing of Joe's father, has them reminiscing and looking at old pictures in Al's photo albums, and a series of pictures Al's never seen before has them on a new case, trying to find more information about Sadie T. Diamond, the author of a chalk message claiming to have committed the perfect murder.

What none of them know yet is that Sadie is closer than they think, and inordinately interested in them, why, they have to figure out, and quickly, because other revelations are coming at them fast and hard: Val, wife of Johnny, Joe's brother, has walked out on her husband after discovering he cheated on her, leaving her phone behind and going off the grid; Omar, Rachel's first boyfriend, walks back into her life when he hires Lauren's firm to investigate a colleague; and Rachel gets the shock of her life when she attends a play and discovers one of the actors shares a name with a boy she hasn't seen in over thirty years, a boy who's supposed to be dead.

With no time for an intermission, because a triple murder has them all on their guard, they must find out why these events are happening, and what their connection is, because, though they don't know it yet, they're all going to be on the stage for the final act that has them travelling to a place from which they might never return, to do a deed that will change things forever...
