Not much time has passed since the thrilling adventure surrounding the stolen treasure of Castle MacGorilla, but our three intrepid investigators-Teddy, Porculina, and Gorilla-are once again called upon to solve a baffling mystery. On this occasion, the action moves from the stark, cold highlands of Scotland to the lush and warmly sunlit Loire Valley in France, but the perils encountered by the trio are no less daunting and the puzzle is, if anything, all the more perplexing. Indeed, it is a puzzle that stretches into the remotest reaches of history, all the way back to ancient Egypt. There are chases, secret doors, samples of Eastern wisdom and French poetry, and biscuits. And then, too, there is the little matter of a recurrent ghostly apparition. Can a small teddy bear detective, however seasoned, aided only by an even smaller plush pig and an easily distracted toy ape-with the occasional assistance of a wise and longsuffering dog-discover the terrible truth before the all-important day of the Cider Festival?
