For hundreds of years Grudge Mountain had lain in cloud-shrouded mystery. But when beautiful Klyda Graeme and her mysterious father came to live there, the quiet valley and ancient, brooding mountain came to life. A gold bullet was found embedded in rancher Guy Manell's front doorstep; his vineyards were destroyed in the night; people were seen on the mountain where they could not possibly be; and tons of boulders suddenly blocked the newly-discovered ascent. Manell was as brave as most, but what was happening frightened him -- until he finally got a clue to the puzzle, with a lot of help from his dog, Gray Dawn.
Albert Payson Terhune (1872 - 1942), a local author of some fame, wrote numerous adventures about Collies, most notably, "Lad, A Dog", "Sunnybank: Home of Lad", and "Further Adventures of Lad". Sunnybank, his home on the eastern shore of Pompton Lakes in northern New Jersey, was originally the home of Terhune's parents, Edward Payson Terhune and Mary Virginia Hawes Terhune. Later as his home with his wife, Anice Stockton Terhune, Sunnybank became famous as "The Place" in the many stories of Terhune. Much of the land once constituting the Sunnybank estate was lost to developers in the 1960's with the house being demolished in 1969. Fortunately though, the central 9.6 acres was preserved through the dedicated efforts of Terhune fans and dog fanciers, and is now Terhune Sunnybank Memorial Park, administered by the Wayne Township Parks Department.
