The Templeton twins make a scene / Weiner, Ellis

Abigail and John Templeton find themselves at TAPAS (the Thespian Academy of the Performing Arts and Sciences) where their father, the illustrious Professor Templeton, has been hired to invent a groundbreaking theatrical device. Once again, there is drama (of course!), silliness, and suspense, as the twins must thwart the dastardly Dean brothers in order to save the invention as well as their father.

Professor Templeton has been hired by the Thespian Academy of the Performing Arts and Sciences to invent something, anything, important (and profitable) but the thirteen-year-old twins, Abigail and John, are suspicious and determined to investigate.
