Emil Gluck was a scientific genius, who had just gone to the electric chair because of the terrible, terrible things he had done between the years 1933 and 1941.

'The enemy of all the world' is Jack London’s exciting short story of a mad scientist who invented something that he should never have invented. Jack London (1876–1916) was an American writer and social activist. He grew up in the working class, but became a worldwide celebrity and one of the highest paid authors of his time. He wrote several novels, which are considered classics today, among these 'Call of the Wild', 'Sea Wolf' and 'White Fang'.
