Legend has it that when the Gabriel Hounds run howling over the crumbling palace of Dar Ibrahim, high in the Adonis Valley of Lebanon, death will follow on their heels. When rich, impetuous Christie Mansel and her cousin Charles arrive unannounced at the decaying palace to visit their eccentric Aunt Harriet, they arrive to the sound of howling dogs. The palace is riddled with hidden passages and the servants are unwilling to let anyone see Harriet during the day. It seems the estate hides an extraordinary secret, one that somebody is willing to kill to keep. In this 1967 tale, Stewart shows her sure hand at the gothic novel, while providing a highly unusual setting.
