In this fifth and final (I swear ) audiobook in my saga of secrets, a class trip to the local natural history museum turns dangerous, or perhaps deadly-and I don't mean in the bored-to-death way-when Cass accidentally breaks a finger off a priceless mummy. Forced to atone for this crime of vandalism, Cass and her friends Max-Ernest and Yo-Yoji go to work for the mummy exhibit's curator, only to be blamed when the mummy disappears. To clear their names-and, they hope, to discover the secret-the trio must solve the case of the missing mummy themselves. In the midst of it all, there's still a secret lurking. Will it finally be revealed? Why should I tell you that? No matter what I do, no amount of warning seems to stick. You're still out there, listening and talking about the secret, and now my life-and chocolate supply-is in the greatest danger yet So please, with a cherry on top, I'm begging you You have to stop this.
