Doyle and Houdini
Sir Arthur Conan Doyle was a huge supporter of Psychical Research and Spiritualism. He was convinced that in the future, everyone would accept mediums and psychic as part of the world.
He was knighted for his action in the Boer War.
Prior to WWI, Doyle foresaw war and studied German military tactics. When war broke out he tried to enlist, and when refused (he *was* 55) he began organizing civilian brigades.
Harry Houdini had faked being a Medium early in his career. When WWI broke out he tried to enlist and when refused (he *was* 43 years old), he instead entertained troops. Rumors persist he had briefly been a spy. Later in life, he spent time debunking psychics and mediums.
Doyle and Houdini were friends.
So WHY hasn’t anyone written a story or created a game setting about the Ghost Brigade, the Great War Psychic Corps of Britain and England run jointly by the Father of Detectives and the Master Escapist?!
