From The Perry Mason TV Show Book
Mauvis Meade, author of the bestseller Chop the Man Down, sends her secretary out to a mountain cabin to pick up a package. Gladys gets lost and her car is stuck in the mud. She walks to a cabin looking for help and meets a mysterious man who seems to know her. While Gladys freshens up, the man leaves and Gladys finds--a dead body.
Perry has to find the mystery man in the cabin in order to clear Gladys, but several things are working against him. First of all, the cabin was rented in Gladys's name. And second, it appears that Gladys was unknowingly working as a courier for the underworld.
Louise Fletcher, one of the stars of the award-winning film One Flew Over the Cuckoo's Nest, plays Gladys the secretary; Trekkies will also know her as the ethically challenged Kai Winn on Star Trek: Deep Space Nine. Also, watch for Norman Fell, who starred as the jerky landlord on "Three's Company," as Casper Pedley.
