Miss Helma Zukas is reluctant to go hiking on the Cascade mountains, but her friend Ruth is insistent. When she agrees to go, Helma, ever the librarian, does her research, reading up on survival techniques, packing like a pro, and making up a list for her irresponsible friend. As usual, Ruth comes unprepared, having neglected to read Helma's list. But even Helma's careful preparation couldn't have anticipated the discovery of a dead body high in the rocky wilderness.
