Shuttling in the Golden Age of Mystery, Wadsworth Camp's thrilling mystery centers on the revival of a Broadway play that is plagued by a mysterious curse that kills its cast members. First published in 1916, the novel is fresh and fast paced and displays the high-standard story-telling qualities that would become the hallmark of the golden age. The novel was later developed into a successful play and silent movie. THE LAST WARNING, based on the book and the play, was the final film of the great silent film director Paul Leni.
