Best remembered for penning the screenplay for the classic film âKing Kongâ, author Edgar Wallace was an astoundingly popular luminary in the action-adventure genre in the early twentieth century. âThe Big Fourâ is a story packed with intrigue, treachery, assassinations, and machinations, and it highlights Wallaceâs unmatched skill in setting a pulse-pounding pace. Wallace was an extremely prolific writer who wrote over 175 novels, plus numerous plays, essays and journalistic articles. During the peak of his success during the 1920âs, it was said that a quarter of all books read in England were written by him. Many of his novels were made into films and TV dramas.
