"Pondering that conundrum is what has kept the dearly departed General Inspectre tethered to Earth long after he should have moved onto the great super-spy base in the sky. Having a ghost haunting the halls of S.U.I.T. wouldn't be so bad...except he's possessed Monocle to serve as his Earthly form! Zeb--along with Cilantro, Bongo, Marsha, and cameos from everyone's favorite Gators--must decipher the series' biggest mystery EVER to free their pal and finish the Inspectre's unfinished business!"-- From publisher description.
