Probably the most famous work in the original series. Holmes pits his wits against a demon dog, a hellhound which has haunted the Baskervilles and is once again coming to reap misery on the family. Of course, Holmes is intrigued. This is the first story published after his supposed death in The Final Problem, coming 8 years after the famous battle at the falls, but it is actually set two years prior to his passing. Another story would bring Holmes back to life.
