Phyllis A. Whitney: Secret of the Stone Face

May 1978 is the Signet publication date for Secret of the Stone Face by Phyllis A. Whitney. Joanna Baird is wondering who carved the angry face in the rock wall of the hotel maze? She was worried that her mother's fiance, the hotel's manager, might be mixed up in this mystery.

Allan Kass shows our teens as they watch someone climb the rock wall. We see the hotel in the background and a beautiful view beyond. My copy, unfortunately, has a tear over the water but it doesn't take away from the beauty of Allan's work.
